In this research1 from the Journal of Scientific and Aesthetic Dermatology, board-certified dermatologist Babar Rao, M.D., FAAD, a professor of dermatology and pathology at Robert Wooden Johnson Medical Faculty, and fellow researchers randomly assigned 60 contributors with zits scars and deeper pores and skin tones to 2 teams.
They in contrast two totally different therapies, one being a chemical peel with 35% glycolic acid and the opposite a microneedling session—each administered each two weeks for 12 weeks.
In case you are unfamiliar, microneedling entails tiny sterilized needles that pierce the pores and skin and stimulate collagen manufacturing, thus encouraging the pores and skin to heal—in flip, the tactic helps cut back the looks and depth of zits scars.
Chemical peels, however, do precisely what you’d count on—chemical exfoliants are used to take away the highest layer of the pores and skin. The pores and skin that grows again as a substitute is probably going smoother and free from discoloration. This helps to reduce the looks of zits scars, too.
So what did the researchers discover? Microneedling offered higher therapy outcomes in comparison with 35% glycolic acid peels in sufferers with darker pores and skin tones.
This research marks a serious stride on the planet of zits scar therapies: Whereas chemical peels should still be an excellent possibility for some (if it really works for you, it really works!), microneedling might display even higher outcomes for zits scars, particularly for these with melanin-rich pores and skin. As at all times, attempt to chat with a dermatologist earlier than reserving any of those therapies.
