Generally speaking, which peel is stronger and more effective for acne pigmentation? TCA peel or PCA peel?

Hi. I heard that TCA and PCA peels are medium depth peels to treat acne pigmentations. What is the difference between these two and which one is more effective? Thanks!

Thanks for your query. TCA peel comprises of tri chloroacetic acid and works better for acne as its depth can be modified according to its concentration and it works better for pigmentation as well as the scars. PCA peel is a combination peel with hydroquinone as its major ingredient. Hydroquinone works only on pigmentation and is not strong enough to cater very deep pigmentation. Hope it helps.
