* Review Dr. Ting's 727+ Q&A on RealSelf

What is DPCP? DiPhenylCyloPropenone (DPCP) is a chemical that acts like immune system booster to help your body fight off the wart virus. The DPCP creates a minor allergic reaction on the skin and may resemble a mosquito bite or small red rash. You will know DPCP is working when it becomes a red bump and may become itchy, this is normal reaction. Dr. William Ting has the experience to use DPCP to treat resistant warts, molluscum and alopecia areata.
DPCP is experimental chemical and is not approved by the FDA. DPCP has been shown not to be mutagenic and is widely used in Canada and Europe. Therefore, ONLY specially trained Medical Assistants or Dr. Ting will apply it. It is a clear liquid, which is swabbed on to the skin using a cotton swab.

DPCP has side effects, some or all of which you may experience. These include itching, blistering, and or skin lightening or darkening of the treated skin. Side effects will be dealt with on an individual basis as they arise.

Women of childbearing age must use reliable method of contraception, as the effects of DPCP on fetus are not known.

This is a monthly treatment you must commit to coming in to Dr. Ting’s office once a month. DPCP does not work for everyone. Depending on the duration and extent of your condition DPCP is effective for some patients.

DPCP is not the only way to treat your skin condition. Please speak with Dr. Ting about other treatment options and their associated risks.

On your first visit you will be sensitized to the DPCP. This means that small amount of DPCP will be applied to your inner arm with a small bandage in place. This will prepare your immune system to react with DPCP upon subsequent application. You will leave the bandage on for 4 hours. Then wash the area with mild soap and warm water. If the area becomes very itchy take off the bandage before the 4 hour period. Wash immediately with mild soap and warm water.

On your return visit, DPCP (at much lower concentration) will be applied directly to the affected area.
