Dr. Sherber uses a concentrated form of TCA to spot treat concerns such as sunken scars (termed the TCA CROSS method) or enlarged oil glands.
- Dr. Sherber first cleans the area to be treated with an acetone solution to remove any oils from the skin. The TCA treatment is then applied precisely until a white frost forms over the spot to be treated and a thin rim of surrounding skin.
- Several treatments may be needed depending on the skin concern being treated.
TCA (trichloracetic acid) is a relative of vinegar (acetic acid) and is safe for topical use on all skin types, but caution must be used with deeper skin tones or on tanned skin. Dr. Sherber often elects to perform a test spot with TCA to ensure that the treated areas will heal without any pigmentation problems.
Preparing for Treatment
- Retinoids should be discontinued for a week prior to having this treatment.
- Sun protection is very important in the days following a peel, and mineral sunscreens are the gentlest approach for sensitive skin types.
- If you have a history of herpes simplex cold sores, we may prescribe an antiviral to take as an adjunct to treatment to prevent an outbreak.
What to Expect
- The peel creates a mild and temporary stinging feeling, but is not painful.
