Erythema multiforme is frequently self-limiting and requires no treatment. The appropriateness of glucocorticoid therapy can be uncertain, because it is difficult to determine if the course will be a resolving one.

Recent research has focused on changing the mixture of keratins produced in the skin. There are 54 known keratin genes—of which 28 belong to the type I intermediate filament genes and 26 to type II—which work as heterodimers. Many of these genes share substantial structural and functional similarity, but they are specialized to cell type and/or conditions under which they are normally produced. If the balance of production could be shifted away from the mutated, dysfunctional keratin gene toward an intact keratin gene, symptoms could be reduced. For example, sulforaphane, a compound found in broccoli, was found to reduce blistering in a mouse model to the point where affected pups could not be identified visually, when injected into pregnant mice (5 µmol/day = 0.9 mg) and applied topically to newborns (1 µmol/day = 0.2 mg in jojoba oil).

As of 2008 clinical research at the University of Minnesota has included a bone marrow transplant to a 2-year-old child who is one of 2 brothers with EB. The procedure was successful, strongly suggesting that a cure may have been found. A second transplant has also been performed on the child's older brother, and a third transplant is scheduled for a California baby. The clinical trial will ultimately include transplants to 30 subjects. However, the severe immunosuppression that bone marrow transplantation requires causes a significant risk of serious infections in patients with large scale blisters and skin erosions. Indeed, at least four patients have died in the course of either preparation for or institution of bone marrow transplantation for epidermolysis bullosa, out of only a small group of patients treated so far.

A pilot study performed in 2015 suggests that systemic granulocyte-colony stimulating factor (G-CSF) may promote increased wound healing in patients with dystrophic epidermolysis bullosa. In this study seven patients with dystrophic epidermolysis bullosa were treated daily with subcutaneous G-CSF for six days and then re-evaluated on the seventh day. After six days of treatment with G-CSF, the size of the open lesions were reduced by a median of 75.5% and the number of blisters and erosions on the patients were reduced by a median of 36.6%.

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.

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

The Epidermolysis Bullosa Activity and Scarring index (EBDASI) is a scoring system that objectively quantifies the severity of epidermolysis bullosa. The EBDASI is a tool for clinicians and patients to monitor the severity of the disease. It has also been designed to evaluate the response to new therapies for the treatment of EB. The EBDASI was developed and validated by Professor Dedee Murrell and her team of students and fellows at the St George Hospital, University of New South Wales, in Sydney, Australia. It was presented at the International Investigative Dermatology congress in Edinburgh in 2013 and a paper-based version was published in the "Journal of the American Academy of Dermatology" in 2014.

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.

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

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.

Usually, a common form of treatment for the condition is a type of hand cream which moisturises the hard skin. However, currently the condition is incurable.

No treatment is needed. If a stork bite lasts longer than 3 years, it may be removed using laser surgery.

Treatment is cause-related, but also symptomatic if the underlying cause is unknown or not correctable. It is also important to note that most ulcers will heal completely without any intervention. Treatment can range from simply smoothing or removing a local cause of trauma, to addressing underlying factors such as dry mouth or substituting a problem medication. Maintaining good oral hygiene and use of an antiseptic mouthwash or spray (e.g. chlorhexidine) can prevent secondary infection and therefore hasten healing. A topical analgesic (e.g. benzydamine mouthwash) may reduce pain. Topical (gels, creams or inhalers) or systemic steroids may be used to reduce inflammation. An antifungal drug may be used to prevent oral candidiasis developing in those who use prolonged steroids. People with mouth ulcers may prefer to avoid hot or spicy foods, which can increase the pain. Self-inflicted ulceration can be difficult to manage, and psychiatric input may be required in some people.

It can be treated with systemic antiviral drugs, such as aciclovir or valganciclovir. Foscarnet may also be used for immunocompromised host with Herpes simplex and acyclovir-resistant Herpes simplex.

The decision to observe or treat a nevus may depend on a number of factors, including cosmetic concerns, irritative symptoms (e.g., pruritus), ulceration, infection, and concern for potential malignancy.

Most stork bites on the face go away completely in about 18 months. Stork bites on the back of the neck usually do not go away.

Treatment includes fluid intake, good oral hygiene and gentle debridement of the mouth, as well as oral acyclovir. In healthy individuals the lesions heal spontaneously in 7–14 days without scarring.

In 2015, an Italian team of scientists, led by Michele De Luca at the University of Modena, successfully treated a seven-year-old Syrian boy who had lost 80% of his skin. The boy's family had fled Syria for Germany in 2013. Upon seeking treatment in Germany, he had lost the epidermis from almost his entire body, with only his head and a patch on his left leg remaining. The group of Italian scientists had previously pioneered a technique to regenerate healthy skin in the laboratory. They used this treatment on the boy by taking a sample from his remaining healthy skin and then genetically modifying the skin cells, using a virus to deliver a healthy version of the LAMB3 gene into the nuclei. The patient underwent two operations in autumn 2015, where the new epidermis was attached. The graft had integrated into the lower layers of skin within a month, curing the boy. The introduction of genetic changes could increase the chances of skin cancer in other patients, but if the treatment is deemed safe in the long term, scientists believe the approach could be used to treat other skin disorders.

The management of a nevus depends on the specific diagnosis, however, the options for treatment generally include the following modalities:

Epithelial keratitis is treated with topical antivirals, which are very effective with low incidence of resistance. Treatment of the disease with topical antivirals generally should be continued for 10–14 days. Aciclovir ophthalmic ointment and Trifluridine eye drops have similar effectiveness but are more effective than Idoxuridine and Vidarabine eye drops. Oral acyclovir is as effective as topical antivirals for treating epithelial keratitis, and it has the advantage of no eye surface toxicity. For this reason, oral therapy is preferred by some ophthalmologists.

Ganciclovir and brivudine treatments were found to be equally as effective as acyclovir in a systematic review.

Valacyclovir, a pro-drug of acyclovir likely to be just as effective for ocular disease, can cause thrombotic thrombocytopenic purpura/Hemolytic-uremic syndrome in severely immunocompromised patients such as those with AIDS; thus, it must be used with caution if the immune status is unknown.

Topical corticosteroids are contraindicated in the presence of active herpetic epithelial keratitis; patients with this disease who are using systemic corticosteroids for other indications should be treated aggressively with systemic antiviral therapy.

The effect of interferon with an antiviral agent or an antiviral agent with debridement needs further assessment.

Docosanol, a saturated fatty alcohol, is a safe and effective topical application that has been approved by the United States Food and Drug Administration for herpes labialis in adults with properly functioning immune systems. It is comparable in effectiveness to prescription topical antiviral agents. Due to its mechanism of action, there is little risk of drug resistance. The duration of symptoms can be shortened a bit if an antiviral, anesthetic, zinc oxide or zinc sulfate cream is applied soon after it starts.

Effective antiviral medications include acyclovir and penciclovir, which can speed healing by as much as 10%. Famciclovir or valacyclovir, taken in pill form, can be effective using a single day, high-dose application and is more cost effective and convenient than the traditional treatment of lower doses for 5–7 days.

Herpetic stromal keratitis is treated initially with prednisolone drops every 2 hours

accompanied by a prophylactic antiviral drug: either topical antiviral or an oral agent such as acyclovir or valacyclovir. The prednisolone drops are tapered every 1–2 weeks depending on the degree of clinical improvement. Topical antiviral medications are not absorbed by the cornea through an intact epithelium, but orally administered acyclovir penetrates an intact cornea and anterior chamber. In this context, oral acyclovir might benefit the deep corneal inflammation of disciform keratitis.

Epidermolysis bullosa simplex may be divided into multiple types:

Currently, there are no treatments available for JEB. However, the disorder can be prevented through good breeding management. Horses that are carriers of JEB should not be incorporated into breeding programs. Although, if breeders are insistent on breeding a carrier, precautions need to be taken to ensure that the other mate is not a carrier as well. Genetic testing for the disorder is highly recommended among breeding programs for the Draft horse and Saddlebred breeds to determine their carrier status.

Junctional epidermolysis bullosa is a skin condition characterized by blister formation within the lamina lucida of the basement membrane zone.

Epidermolysis bullosa simplex (EBS),is a disorder resulting from mutations in the genes encoding keratin 5 or keratin 14.

Blister formation of EBS occurs at the dermoepidermal junction. Sometimes EBS is called "epidermolytic".

Herpes outbreaks should be treated with antiviral medications like Acyclovir, Valacyclovir, or Famcyclovir, each of which is available in tablet form.

Oral antiviral medication is often used as a prophylactic to suppress or prevent outbreaks from occurring. The recommended dosage for suppression therapy for recurrent outbreaks is 1,000 mg of valacyclovir once a day or 400 mg Acyclovir taken twice a day. In addition to preventing outbreaks, these medications greatly reduce the chance of infecting someone while the patient is not having an outbreak.

Often, people have regular outbreaks of anywhere from 1 to 10 times per year, but stress (because the virus lies next to the nerve cells), or a weakened immune system due to a temporary or permanent illness can also spark outbreaks. Some people become infected but fail to ever have a single outbreak, although they remain carriers of the virus and can pass the disease on to an uninfected person through asymptomatic shedding (when the virus is active on the skin but rashes or blisters do not appear).

The use of antiviral medications has been shown to be effective in preventing acquisition of the herpes virus. Specific usage of these agents focus on wrestling camps where intense contact between individuals occur on a daily basis over several weeks. They have also been used for large outbreaks during seasonal competition, but further research needs to be performed to verify efficacy.
