UV Phototherapy

Dermatologists typically encourage you to practice sun smart behaviors and limit your exposure to ultraviolet (UV) light. This is because UV light causes mutations in the skin that may lead to skin cancer AND lowers your immunity/inflammation in the skin. Some people however suffer from too much inflammation in their skin. These conditions include but are not limited to atopic dermatitis/eczema, psoriasis, pruritus/itching, and vitiligo.

Phototherapy is the use of light to treat skin disorders. In order to limit the side effects of phototherapy, we exclusively offer narrowband UVB. Narrowband UVB emits only wavelengths of 311-312 nm providing maximal effectiveness of decreased inflammation in the skin and shorter more effective treatments.

By eliminating wavelengths below 300 nm, the risk for severe burning and the increased risk of skin cancer are diminished.


Patch Testing

Some people suffer with rashes that may be caused from an allergy to something they come in contact with in the environment. This type of rash is called contact dermatitis. Poison ivy is a classic example. Patch testing is a type of skin allergy testing where allergens/ingredients/products are placed in contact with your skin for 48 hours to help determine to what you are allergic. There are no needles or injections involved. We offer extended allergen patch testing at Johnson Dermatology.

After we determine which allergens to which you are allergic, we encourage you to meet with our skin care experts to discuss your reactions and make a plan to improvement of your symptoms at no extra charge. If you think you have contact dermatitis or a contact allergy, contact us to schedule an appointment.
