When considering the right time and age for a chemical peel, several factors will help answer the question, "How old do you have to be?".1. What is the problem to be addressed? Acne, sun damage, hyperpigmentation, wrinkles - each are addressed by different types of peels. Some can be used in teens, and others are reserved for 30s and beyond.2. What type of peel is being considered? Salicylic acid is best for people in their teens and 20s for acne, but can also be used in the 30s and 40s for hyperpigmentation. Other light peels are safe at any age. Medium depth peels, such as Jessner's and TCA combination, should really be reserved for patients over 30-40 who want improvement in chronic sun damage, pre-cancerous lesions, and fine wrinkling.3. Who is doing the peel? Be sure you're seeing a responsible physician for medical grade peels. Be careful of aestheticians who may try to oversell particular peels for problems that can't be corrected with peels. And don't ever order a medical grade peel over the internet for home use. You'll never be old enough do this.I'm guessing by your username that you were born in 77, which makes you 32 or 33 years old. You're pretty safe for any properly applied peel at this point if that's the case.
