Is a 40% TCA peel strong?

Hi renee730. TCA peels do come in a variety of strengths depending upon why they are being used and where they are being applied. A 40% is a strong dose. Skin that is thin and delicate may use 15% (like under eyes), while thicker or more damaged skin (like on a décolleté) requires 35%. Certain skin types should never have a TCA peel due to the risks, such as of post-inflammatory hyper pigmentation. Be sure to have a proper skin analysis before embarking upon any kind of chemical peel. Consultation with a board certified Plastic surgeon will help you prepare before the peel, and give you guidelines to ensure a safe course afterwards. good luck!

TCA peels at 40% concentration is rather strong and can be problematic if applied by yourself. In our office, we use a lesser concentration with multiple passes. Best, Dr. Karamanoukian Los Angeles
