Can I use Glycolic acid and tns serum at the same time at night?

Thanks for your query. Yes glycolic acid and tns serum can be used together at night. Glycolic acid acts as a skin lightening agent and tns serum mainly consists of Human Fibroblast Conditioned Media, Water (Aqua), Cetyl Ethylhexanoate, Olea Europaea (Olive) Fruit Unsaponifiables, Alpha-arbutin, Isoceteth-20, Arachidyl Alcohol, Glycerin, Ethoxydiglycol, Butyrospermum Parkii (Shea Butter), Palmitoyl Tripeptide-5, Ergothioneine, Dipalmitoyl Hydroxyproline, Hydrolyzed Silk etc which acts for skin rejuvenation so it canbe used together. Hope it helps. All The Best

Try not to overly dry out your skin. Between sessions of chemical peeling, you may want to use Melarase PM and Melapads to maintain results and reduce pigmentation. Best, Dr. KaramanoukianLos Angeles
