Do chemical peels build collagen?
You’re so welcome! The answer is yes, but not much. The very superficial peels just refresh the outer layer, the epidermis. Medium to deeper peels will generally build a little collagen in the superficial dermis where the collagen, living cells, etc. are. More on peels.
Deeper peels, in my opinion, aren’t safe unless done by experts because you start to risk permanent pigment problems and sometimes scars as side effects. Lasers and radiofrequency/ultrasound, done well and by experts, are safer and more effective at building deep collagen. The same thing is true of the filler Sculptra.
Hope this helps, Dr. I
