In persistent or especially bad rashes, an antifungal cream often has to be used. In cases that the rash is more of an irritation, a "mild" topical corticosteroid preparation, e.g. hydrocortisone cream, is used. As it is often difficult to tell a fungal infection apart from a mere skin irritation, many physicians prefer an corticosteroid-and-antifungal combination cream such as hydrocortisone/miconazole.

Various moisture-absorbing powders, such as talcum or starch, reduce moisture but may introduce other complications. Airborne powders of any sort can irritate lung tissue, and powders made from starchy plants (corn, arrowroot) provide food for fungi and are not recommended by the American Academy of Dermatology.

There are many topical antifungal drugs useful in the treatment of athlete's foot including: miconazole nitrate, clotrimazole, tolnaftate (a synthetic thiocarbamate), terbinafine hydrochloride, butenafine hydrochloride and undecylenic acid. The fungal infection may be treated with topical antifungal agents, which can take the form of a spray, powder, cream, or gel. Topical application of an antifungal cream such as terbinafine once daily for one week or butenafine once daily for two weeks is effective in most cases of athlete's foot and is more effective than application of miconazole or clotrimazole. Plantar-type athlete's foot is more resistant to topical treatments due to the presence of thickened hyperkeratotic skin on the sole of the foot. Keratolytic and humectant medications such as urea, salicyclic acid (Whitfield's ointment), and lactic acid are useful adjunct medications and improve penetration of antifungal agents into the thickened skin. Topical glucocorticoids are sometimes prescribed to alleviate inflammation and itching associated with the infection.

A solution of 1% potassium permanganate dissolved in hot water is an alternative to antifungal drugs. Potassium permanganate is a salt and a strong oxidizing agent.

For severe or refractory cases of athlete's foot oral terbinafine is more effective than griseofulvin. Fluconazole or itraconazole may also be taken orally for severe athlete's foot infections. The most commonly reported adverse effect from these medications is gastrointestinal upset.

Most cases are treated by application of topical antifungal creams to the skin, but in extensive or difficult to treat cases systemic treatment with oral medication may be required. The over-the-counter options include tolnaftate.

Among the available prescription drugs, the evidence is best for terbinafine and naftifine, but other agents may also work.

Topical antifungals are applied to the lesion twice a day for at least 3 weeks. The lesion usually resolves within 2 weeks, but therapy should be continued for another week to ensure the fungus is completely eradicated. If there are several ringworm lesions, the lesions are extensive, complications such as secondary infection exist, or the patient is immunocompromised, oral antifungal medications can be used. Oral medications are taken once a day for 7 days and result in higher clinical cure rates. The antifungal medications most commonly used are itraconazole and terbinafine.

The benefits of the use of topical steroids in addition to an antifungal is unclear. There might be a greater cure rate but no guidelines currently recommend its addition. The effect of Whitfield's ointment is also unclear.

Intertrigo is treated by addressing associated infections, by removing moisture from the site, and by using substances at the site to help maintain skin integrity. If the individual is overweight, losing weight may also help. Relapses of intertrigo are common.

Keeping the area of the intertrigo dry and exposed to the air can help prevent recurrences, as can removing moisture from the area using absorbent fabrics or body powders, including plain cornstarch and judiciously used antiperspirants.

Greases, oils, and barrier ointments, may help by protecting skin from moisture and from friction. Antifungal powders, most commonly clotrimazole 1%, may also be used in conjunction with a barrier ointment. Diaper rash ointment can also help.

Fungal infections associated with intertrigo may be treated with prescription antifungals applied directly to the skin (in most cases) or systemic antifungals, including fluconazole, nystatin, and griseofulvin.

Intertrigo is also a known symptom of vitamin B6 deficiency.

Sunscreen and protective clothing should also be used during the hottest part of the day to avoid blisters from sunburn. Avoiding sunlight during midday is the best way to avoid blisters from sunburn. Protective gloves should be worn when handling detergents, cleaning products, solvents and other chemicals.

Friction blisters, caused by rubbing against the skin, can be prevented by reducing the friction to a level where blisters will not form. This can be accomplished in a variety of ways.

Blisters on the feet can be prevented by wearing comfortable, well-fitting shoes and clean socks. Inherently ill-fitting or stiffer shoes, such as high heels and dress shoes, present a larger risk of blistering. Blisters are more likely to develop on skin that is moist, so socks that manage moisture or frequent sock changes will aid those with particularly sweaty feet. While exercising or playing sports, special sports socks can help keep feet drier and reduce the chance of blisters. Before going for a long walk, it is also important to ensure that shoes or hiking boots have been properly broken in.

Even before a "hot" or irritated area on the foot is felt, taping a protective layer of padding or a friction-reducing interface between the affected area and the footwear can prevent the formation of a blister. Bandages, moleskin and tapes generally must be applied to the foot daily, and most have a very high coefficient of friction (COF), but a friction-management patch applied to the shoe will remain in place much longer, throughout many changes of socks and insoles. This type of intervention may be used with footwear that is worn daily, with specialty shoes and boots like hockey skates, ice skates, inline skates, ski boots and cleats, or even with orthotic braces and splints. For periods of sustained use such as hiking and trail running, especially where water ingress or moisture build up in the shoe or boot can occur, moisture wicking liner socks can provide the required friction protection.

To avoid friction blisters on the hands, gloves should be worn when using tools such as a shovel or pickaxe, doing manual work such as gardening, or using sports equipment like golf clubs or baseball bats. Oars used for competitive rowing are known for causing frequent blisters on the hands of oarsmen. Weightlifters are also prone to blisters as are gymnasts from the friction developed by the rubbing against the bars. To further reduce the occurrence one can tape the hands, and there are also a number of products on the market that claim to reduce the occurrence of blisters. These are all intended to be worn as a liner underneath a glove. The majority of these offerings simply add padding and create a layer that reduces the coefficient of friction between the skin and the glove.

A lubricant, typically talcum powder, can be used to reduce friction between skin and apparel in the short term. People put talcum powder inside gloves or shoes for this purpose, although this type of lubricant will increase the friction in the long term, as it absorbs moisture. Increased friction makes blisters more likely.

Treatments for tinea versicolor include:

- Topical antifungal medications containing selenium sulfide are often recommended. Ketoconazole (Nizoral ointment and shampoo) is another treatment. It is normally applied to dry skin and washed off after 10 minutes, repeated daily for two weeks. Ciclopirox (Ciclopirox olamine) is an alternative treatment to ketoconazole, as it suppresses growth of the yeast "Malassezia furfur". Initial results show similar efficacy to ketoconazole with a relative increase in subjective symptom relief due to its inherent anti-inflammatory properties. Other topical antifungal agents such as clotrimazole, miconazole, terbinafine, or zinc pyrithione can lessen symptoms in some patients. Additionally, hydrogen peroxide has been known to lessen symptoms and, on certain occasions, remove the problem, although permanent scarring has occurred with this treatment in some sufferers. Clotrimazole is also used combined with selenium sulfide.

- Oral antifungals including ketoconazole or fluconazole in a single dose, or ketoconazole for seven days, or itraconazole can be used. The single-dose regimens, or pulse therapy regimens, can be made more effective by having the patient exercise 1–2 hours after the dose, to induce sweating. The sweat is allowed to evaporate, and showering is delayed for a day, leaving a film of the medication on the skin.

Keratosis pilaris is medically harmless, but many individuals may seek treatment as the condition can cause emotional distress. Topical creams and lotions are currently the most commonly used treatment for keratosis pilaris, specifically those consisting of moisturizing or keratolytic treatments, including urea, lactic acid, glycolic acid, salicylic acid, vitamin D, or topical retinoids such as tretinoin. Corticosteroid creams can also be used as a treatment for KP. Improvement of the skin often takes months and the bumps are likely to return. Limiting time in the shower and using gentle exfoliation to unplug pores can help. Many products are available that apply exfoliation and alpha or beta hydroxy acids.

Some cases of keratosis pilaris have been successfully treated with laser therapy, which involves passing intense bursts of light into targeted areas of the skin. Depending on the body's response to the treatment, multiple sessions over the course of a few months may be necessary.

Salicylic acid — The treatment of warts by keratolysis involves the peeling away of dead surface skin cells with keratolytic chemicals such as salicylic acid or trichloroacetic acid. These are available in over-the-counter products or, in higher concentrations, may need to be prescribed by a physician. A 12-week daily treatment with salicylic acid has been shown to lead to a complete clearance of warts in 10–15% of the cases.

Formic acid — Topical formic acid is a common treatment for plantar warts, which works by being applied over a period of time causing the body to reject the wart.

Immunotherapy — Intralesional injection of antigens (mumps, "candida" or trichophytin antigens USP) is a new wart treatment which may trigger a host immune response to the wart virus, resulting in wart resolution. It is now recommended as a second-line therapy.

Shampoos use a combination of special ingredients to control dandruff.

A number of treatments have been found to be effective. A 2012 review of different treatments for skin warts in otherwise healthy people concluded modest benefit from salicylic acid and cryotherapy appears similar to salicylic acid.

Antifungal treatments including ketoconazole, zinc pyrithione and selenium disulfide have been found to be effective. Ketoconazole appears to have a longer duration of effect.

Ketoconazole is a broad spectrum antimycotic agent that is active against "Candida" and "M. furfur". Of all the antifungals of the imidazole class, ketoconazole has become the leading contender among treatment options because of its effectiveness in treating seborrheic dermatitis as well.

Ciclopirox is widely used as an anti-dandruff agent in most preparations.

Corns and calluses are easier to prevent than to treat. When it is usually not desirable to form a callus, minimizing rubbing and pressure will prevent callus formation. Footwear should be properly fitted, gloves may be worn, and protective pads, rings or skin dressings may be used. People with poor circulation or sensation should check their skin often for signs of rubbing and irritation so they can minimize any damage.

Because fungi prefer warm, moist environments, preventing ringworm involves keeping skin dry and avoiding contact with infectious material. Basic prevention measures include:

- Washing hands after handling animals, soil, and plants.

- Avoiding touching characteristic lesions on other people.

- Wearing loose-fitting clothing.

- Practicing good hygiene when participating in sports that involve physical contact with other people.

Calluses and corns may go away by themselves eventually, once the irritation is consistently avoided. They may also be dissolved with keratolytic agents containing salicylic acid, sanded down with a pumice stone or silicon carbide sandpaper or filed down with a callus shaver, or pared down by a professional such as a podiatrist or a foot health practitioner.

Antifungal drugs are used to treat mycoses. Depending on the nature of the infection, a topical or systemic agent may be used.

Example of antifungals include: fluconazole which is the basis of many over-the-counter antifungal treatments. Another example is amphotericin B which is more potent and used in the treatment of the most severe fungal infections that show resistance to other forms of treatment and it is administered intravenously.

Drugs to treat skin infections are the azoles: ketoconazole, itraconazole, terbinafine among others.

Yeast infections in the vagina, caused by "Candida albicans", can be treated with medicated suppositories such as tioconazole and pessaries whereas skin yeast infections are treated with medicated ointments.

There are 4 aspects to the treatment of angular cheilitis. Firstly, potential reservoirs of infection inside the mouth are identified and treated. Oral candidiasis, especially denture-related stomatitis is often found to be present where there is angular cheilitis, and if it is not treated, the sores at the corners of the mouth may often recur. This involves having dentures properly fitted and disinfected. Commercial preparations are marketed for this purpose, although dentures may be left in dilute (1:10 concentration) household bleach overnight, but only if they are entirely plastic and do not contain any metal parts, and with rinsing under clean water before use. Improved denture hygiene is often required thereafter, including not wearing the denture during sleep and cleaning it daily. For more information, see Denture-related stomatitis.

Secondly, there may be a need to increase the vertical dimension of the lower face to prevent overclosure of the mouth and formation of deep skin folds. This may require the construction of a new denture with an adjusted bite. Rarely, in cases resistant to normal treatments, surgical procedures such as collagen injections (or other facial fillers such as autologous fat or crosslinked hyaluronic acid) are used in an attempt to restore the normal facial contour. Other measures which seek to reverse the local factors that may be contributing to the condition include improving oral hygiene, stopping smoking or other tobacco habits and use of a barrier cream (e.g. zinc oxide paste) at night.

Thirdly, treatment of the infection and inflammation of the lesions themselves is addressed. This is usually with topical antifungal medication, such as clotrimazole, amphotericin B, ketoconazole, or nystatin cream. Some antifungal creams are combined with corticosteroids such as hydrocortisone or triamcinolone to reduce inflammation, and certain antifungals such as miconazole also have some antibacterial action. Diiodohydroxyquinoline is another topical therapy for angular cheilitis. If "Staphylococcus aureus" infection is demonstrated by microbiological culture to be responsible (or suspected), the treatment may be changed to fusidic acid cream, an antibiotic which is effective against this type of bacteria. Aside from fusidic acid, neomycin, mupirocin, metronidazole, and chlorhexidine are alternative options in this scenario.

Finally, if the condition appears resistant to treatment, investigations for underlying causes such as anemia or nutrient deficiencies or HIV infection. Identification of the underlying cause is essential for treating chronic cases. The lesions may resolve when the underlying disease is treated, e.g. with a course of oral iron or B vitamin supplements. Patch testing is recommended by some in cases which are resistant to treatment and where allergic contact dermatitis is suspected.

Skin ulcers may take a very long time to heal. Treatment is typically to avoid the ulcer getting infected, remove any excess discharge, maintain a moist wound environment, control the edema, and ease pain caused by nerve and tissue damage.

Topical antibiotics are normally used to prevent the ulcer getting infected, and the wound or ulcer is usually kept clear of dead tissue through surgical debridement.

Commonly, as a part of the treatment, patients are advised to change their lifestyle if possible and to change their diet. Improving the circulation is important in treating skin ulcers, and patients are consequently usually recommended to exercise, stop smoking, and lose weight.

In recent years, advances have been made in accelerating healing of chronic wounds and ulcers. Chronic wounds produce fewer growth hormones than necessary for healing tissue, and healing may be accelerated by replacing or stimulating growth factors while controlling the formation of other substances that work against them.

Leg ulcers can be prevented by using compression stockings to prevent blood pooling and back flow. It is likely that a person who has had a skin ulcer will have it again; use of compression stockings every day for at least 5 years after the skin ulcer has healed may help to prevent recurrence.

Keeping the skin clean and dry, as well as maintaining good hygiene, will help larger topical mycoses. Because fungal infections are contagious, it is important to wash after touching other people or animals. Sports clothing should also be washed after use.

Even though there is no way to cure the disease itself, there are ways to dampen the symptoms. These include medical help in form of pills, and using heavy lotions and oils.

To maintain the good health of the skin after the symptoms have dampened the person with the disease are advised to go on normally with their lives but to take precautions while showering. This is to take shorter, colder baths than usual to not stress the skin. It is also known to help to use bar-soap, instead of a liquid body wash.

There is no cure for Schamberg's disease; however, the itching can be controlled by a cortisone cream, and Colchicine treatment has been successfully used to prevent recurrence of the symptoms. This condition is not life-threatening or a major health concern. The only problem that patients will encounter is the itching and discoloration of the skin. It is recommended that patients take a vitamin C supplement to promote collagen production, which will help make the skin look and feel healthier. To prevent further irritation of the lesions, patients should avoid food with artificial colors and preservatives. Some people can be allergic to preservatives, which can cause the body to initiate an allergic reaction by further irritating those lesions. Several research studies have indicated that Schamberg's disease can be controlled and the number of lesions can be reduced with use a drug called aminaphtone. This drug helps improve capillary fragility and it prevents and controls the purpuric lesions.

A patient with Schamberg's disease can live a normal and healthy life. Since there is no proven cure for this condition, the patient will have to endure the lesions on his or her skin. With appropriate treatments, the condition may get better. Although the skin lesions are not life-threatening, it may cause a cosmetic concern for some individuals. Skin lesions may cause psychological discomfort, where patients may require reassurance to help with stress and anxiety. There are a few rare cases of T-cell lymphoma that has developed from Schamberg's disease.This is not a cause for concern, since the risk factors associated with Schamberg's disease are relatively low.

For every form of contagious infection, there is a readily available form of medication that can be purchased at any pharmacy. It is a commonly held belief among wrestlers, however, that these ointments do not treat symptoms Sometimes wrestlers who don’t want to report an infection to their coach will resort to unusual and unhealthy treatments. Included among these ‘home remedies’ are nail polish remover, bleach, salt, and vinegar solutions, which are used to either suffocate or burn the infection, often leaving extensive scars. The remedies, while sometimes successful, are not guaranteed to actually kill the infection, often only eliminating visible symptoms temporarily. Even though the infection may no longer be symptomatic, it can still be easily transmitted to other individuals. Because of this, it is recommended that wrestlers attempting to treat skin infections use conventional medicine, as prescribed by a physician.

Treatments involve antibiotics that cover for "Pseudomonas aeruginosa". Antipseudomonal penicillins, aminoglycosides, fluoroquinolones, third generation cephalosporins or aztreonam can be given. Usually, the antibiotics are changed according to the culture and sensitivity result. In patients with very low white blood cell counts, Granulocyte-macrophage colony-stimulating factor may be given. Depending on the causal agents, antivirals or antifungals can be added.

Surgery will be needed if there is extensive necrosis not responding to medical treatments.
