Antibiotic creams are the preferred treatment for mild cases of impetigo, despite their limited systemic absorption. Such prescribed ointments include neosporin, fusidic acid, chloramphenicol and mupirocin. More severe cases of impetigo however (especially bullous impetigo) will likely require oral agents with better systemic bioavailability, such as cephalexin. Cases that do not resolve with initial antibiotic therapy or require hospitalization may also be indicative an MRSA infection, which would require the use of agents specifically able to treat it, such as clindamycin.

Antibiotic treatment typically last 7–10 days, and although highly effective some cases of methicillin resistant S. aureus (MRSA) may require longer therapy depending on the severity of infection and how much it has spread.

Since the common pathogens involved with impetigo are bacteria naturally found on the skin, most prevention (especially in children), is targeted towards appropriate hygiene, wound cleaning, and minimizing scratching (i.e. by keeping nails trimmed and short). Avoiding close contact and sharing of items such as towels with potentially infected individuals is also recommended.

For generations, the disease was treated with an application of the antiseptic gentian violet. Today, topical or oral antibiotics are usually prescribed. Mild cases may be treated with bactericidal ointment, such as mupirocin. In 95% of cases, a single antibiotic course results in resolution in children. It has been advocated that topical disinfectants are not nearly as efficient as antibiotics, and therefore should be avoided.

More severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin, or erythromycin. Alternatively, amoxicillin combined with clavulanate potassium, cephalosporins (first-generation) and many others may also be used as an antibiotic treatment. Alternatives for people who are seriously allergic to penicillin or infections with MRSA include doxycycline, clindamycin, and SMX-TMP. When streptococci alone are the cause, penicillin is the drug of choice.

When the condition presents with ulcers, valacyclovir, an antiviral, may be given in case a viral infection is causing the ulcer.

The mainstay of treatment for SSSS is supportive care along with eradication of the primary infection. Conservative measures include rehydration, antipyretics (e.g., ibuprofen, aspirin, and paracetamol), management of thermal burns, and stabilization. Parenteral antibiotics to cover "S. aureus" should be administered. Most strains of "S. aureus" implicated in SSSS have penicillinases, and are therefore penicillin resistant. Therefore, treatment with Nafcillin, oxacillin, or vancomycin is typically indicated. Clindamycin is sometimes also used because of its inhibition of exotoxins.

There is not enough evidence to recommend alternative medicine such as tea tree oil or honey.

A boil may clear up on its own without bursting, but more often it will need to be opened and drained. This will usually happen spontaneously within two weeks. Regular application of a warm moist compress, both before and after a boil opens, can help speed healing. The area must be kept clean, hands washed after touching it, and any dressings disposed of carefully, in order to avoid spreading the bacteria. A doctor may cut open or "lance" a boil to allow it to drain, but squeezing or cutting should not be attempted at home, as this may further spread the infection. Antibiotic therapy may be recommended for large or recurrent boils or those that occur in sensitive areas (such as the groin, breasts, armpits, around or in the nostrils, or in the ear). Antibiotics should not be used for longer than one month, with at least two months (preferably longer) between uses, otherwise it will lose its effectiveness. If the patient has chronic (more than two years) boils, removal by plastic surgery may be indicated.

Furuncles at risk of leading to serious complications should be incised and drained if antibiotics or steroid injections are not effective. These include furuncles that are unusually large, last longer than two weeks, or occur in the middle of the face or near the spine. Fever and chills are signs of sepsis and indicate immediate treatment is needed.

Staphylococcus aureus has the ability to acquire antimicrobial resistance easily, making treatment difficult. Knowledge of the antimicrobial resistance of "S. aureus" is important in the selection of antimicrobials for treatment.

The prognosis of SSSS in children is excellent, with complete resolution within 10 days of treatment, and without significant scarring. However, SSSS must be differentiated carefully from toxic epidermal necrolysis, which carries a poor prognosis. The prognosis in adults is generally much worse, and depends upon various factors such as time to treatment, host immunity, and comorbidities.

Corticosteroids and other immunosuppressive medications have historically been employed to reduce pemphigus symptoms, yet steroids are associated with serious and long-lasting side effects and their use should be limited as much as possible. Intravenous immunoglobulin, mycophenolate mofetil, methotrexate, azathioprine, and cyclophosphamide have also been used with varying degrees of success.

An established alternative to steroids are monoclonal antibodies such as rituximab, which are increasingly being used as first-line treatment. In numerous case series, many patients achieve remission after one cycle of rituximab. Treatment is more successful if initiated early on in the course of disease, perhaps even at diagnosis. Rituximab treatment combined with monthly IV immunoglobulin infusions has resulted in long-term remission with no recurrence of disease in 10 years after treatment was halted. This was a small trial study of 11 patients with 10 patients followed to completion.

Research into using genetically modified T-cells to treat pemphigus vulgaris in mice was reported in 2016. Rituximab indiscriminately attacks all B cells, which reduces the body's ability to control infections. In the experimental treatment, human T cells are genetically engineered to recognize only those B cells that produce antibodies to desmoglein 3.

Topical and intralesional (injected into the affected areas) corticosteroid drugs may be used, such as fluocinonide, clobetasol propionate or triamcinolone acetonide. Oral candidiasis may develop with long term topical steroid use, and sometimes antimycotics such as miconazole gel or chlorhexidine mouthwash are used to prevent this. Topical ciclosporin is sometimes used.

Dapsone is sometimes used as a steroid sparing agent. The dose is often increased very slowly in order to minimize side effects. Systemic steroids, such as prednisone or prednisolone may be needed in severe cases. Many other drugs have been used to treat mucous membrane pemphoid, including azathioprine, cyclophosphamide, methotrexate, thalidomide, mycophenolate mofetil, leflunomide, sulphasalazine, sulphapuridine, sulphamethoxypiridazine, tetracyclines (e.g. minocycline, doxycycline) and nicotinamide.

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.

Plasmapheresis appears to help some cases. Sometimes surgical procedures are required to repair scars, prevent complications such as blindness, upper airway stenosis or esophageal stricture.

First-line therapy for disseminated or localized instances of pyoderma gangrenosum is systemic treatment by corticosteroids and ciclosporin. Topical application of clobetasol, mupirocin, and gentamicin alternated with tacrolimus can be effective.

Pyoderma gangrenosum ulcers demonstrate pathergy, that is, a worsening in response to minor trauma or surgical debridement. Significant care should be taken with dressing changes to prevent potentially rapid wound growth. Many patients respond differently to different types of treatment, for example some benefit from a moist environment, so treatment should be carefully evaluated at each stage.

Papules that begin as small "spouts" can be treated with Dakins Solution to prevent infection and wound clusters also benefit from this disinfectant. Wet to dry applications of Dakins can defeat spread of interior infection. Heavy drainage can be offset with Coban dressings. Grafting is not recommended due to tissue necrosis.

If ineffective, alternative therapeutic procedures include systemic treatment with corticosteroids and mycophenolate mofetil; mycophenolate mofetil and ciclosporin; tacrolimus; thalidomide; infliximab; or plasmapheresis.

There is currently a phase III trial for the use of the IL-1B modulating agent gevokizumab in treating the ulcers of pyoderma gangrenosum.

If the cradle cap is not severe, it could simply be combed out gently after bathing. The softened scales can then be brushed away with a soft brush, comb or cloth, but if not done very gently, this could worsen the condition and bring about temporary hair loss. Applying petroleum jelly (e.g., Vaseline) liberally overnight is another popular treatment. The softened scales either fall off during the night, or can be brushed off in the morning. Making a paste from sodium bicarbonate (baking soda) and leaving it on the affected area for 10 minutes can also help lift the scales. There have been no studies done on these treatments.

There is broad disagreement regarding the role of shampoos. Some sources warn against frequent shampooing, others recommend it. Mild baby shampoo is often recommended, but the exact denotation of the label "mild" in this context is not quite clear. Baby shampoos often contain detergent surfactants, perfumes, quaternium-15 and other eczemagenic irritants. Again, no studies have been performed on non-prescription shampoos.

In stubborn cases some doctors may recommend keratolytic (dandruff) shampoos (e.g. with sulfur, selenium, zinc pyrithione, or salicylic acid) while others warn against the use of medicated shampoos in newborns due to systemic absorption. Dandruff shampoos often contain sodium dodecyl sulfate, a noted skin irritant.

Steroid and tar preparations have also been used but may have drawbacks. Immunomodulators (tacrolimus/Protopic, pimecrolimus/Elidel) have not been approved for babies under two years.

Ketoconazole shampoos and creams are currently shown to be the most effective medical treatment of moderate to serious cradle cap. Research indicates that this anti-fungal medication is not absorbed into the bloodstream.

Treatments include class I topical steroids (clobetasol, halobetasol, etc.) which in some studies have proven to be equally effective as systemic, or pill, therapy and somewhat safer. However, in difficult-to-manage or widespread cases, systemic prednisone and powerful steroid-free immunosuppressant medications, such as methotrexate, azathioprine or mycophenolate mofetil, may be appropriate. Antibiotics such as tetracycline or erythromycin may also control the disease, particularly in patients who cannot use corticosteroids. The anti-CD20 monoclonal antibody rituximab has been found to be effective in treating some otherwise refractory cases of bullous pemphigoid.

IgA-mediated pemphigoid can often be difficult to treat even with usually effective medications such as rituximab.

Typical medical advice is to use diluted baby shampoo on a cotton swab to cleanse the eyelid. There is no agreement on the dilution, which ranges from a few drops to a half cup warm water, to a 50/50 mix.

Many different treatments have been reported for cutaneous lichen planus, however there is a general lack of evidence of efficacy for any treatment. Treatments tend to be prolonged, partially effective and disappointing. The mainstay of localized skin lesions is topical steroids. Additional treatments include retinoids, such as acitretin, or sulfasalazine. Narrow band UVB phototherapy or systemic PUVA therapy are known treatment modalities for generalized disease.

Reassurance that the condition is benign, elimination of precipitating factors and improving oral hygiene are considered initial management for symptomatic OLP, and these measures are reported to be useful. Treatment usually involves topical corticosteroids (such as betamethasone, clobetasol, dexamethasone, and triamcinolone) and analgesics, or if these are ineffective and the condition is severe, the systemic corticosteroids may be used. Calcineurin inhibitors (such as pimecrolimus, tacrolimus or cyclosporin) are sometimes used.

Azathioprine is a steroid-sparing agent used in combination with Prednisone. It functions by inhibiting RNA and DNA synthesis.

Initial treatment involves addressing any existing infections that may have occurred due to the broken state of the skin. Existing wounds are treated with warm compresses, non-adherent (non-stick) dressing, and topical antibiotic ointment. Immunosuppressive agents are administered in attempt to decrease blistering; this is not often effective. The first medication given aiming to heal the wounds are high dose corticosteroids. This is followed by steroid sparing agents which may reduce steroid intake and therefore lessen the side effects. Skin lesions are more likely to respond to this line of treatment than mucosal lesions. However, a high level of caution is advised in patients with a confirmed malignancy, where immunosuppression is vital and dictates treatment options. If the initial therapy fails to control the symptoms of PNP, and the condition of the patient deteriorates, a more aggressive approach may be necessary.

Because the eruption is transient and self-limiting, no treatment is indicated.

Unlike most other manifestations of Tinea dermatophyte infections, Kerion is not sufficiently treated with topical antifungals and requires systemic therapy. Typical therapy consists of oral antifungals, such as griseofulvin or terbinafine, for a sustained duration of at least 6-8 weeks depending on severity. Successful treatment of kerion often requires empiric bacterial antibiotics given the high prevalence of secondary bacterial infection.

Oral retinoids have proven effective in treating this disorder. Depending on the side effects they may improve the quality of life. Examples are etretinate, acitretin, isotretinoin

Physicians often prescribe the antibiotic trimethoprim-sulfamethoxazole to prevent bacterial infections. This drug also has the benefit of sparing the normal bacteria of the digestive tract. Fungal infection is commonly prevented with itraconazole, although a newer drug of the same type called voriconazole may be more effective. The use of this drug for this purpose is still under scientific investigation.

There is no cure for IBS but in the future gene therapy may offer a cure.

Treatments for IBS generally attempt to improve the appearance of the skin and the comfort of the sufferer. This is done by exfoliating and increasing the moisture of the skin. Common treatments include:

- Emollients: moisturisers, petroleum jelly or other emolients are used, often several times a day, to increase the moisture of the skin.

- Baths: long baths (possibly including salt) several times a week are used to soften the skin and allow exfoliation.

- Exfoliating creams: creams containing keratolytics such as urea, salicylic acid and lactic acid may be useful.

- Antiseptic washes: antiseptics may be used to kill bacteria in the skin and prevent odour.

- Retenoids: very severe cases may use oral retinoids to control symptoms but these have many serious side effects including, in the case of IBS, increased blistering.
