  • Daily exfoliating ingredient in a hydrating face serum

    Posted by Nadeem on March 31, 2023 at 9:13 am

    Hello.

    I am looking for a mild, non-irritating, common and affordable exfoliating ingredient to be used in a hydrating face serum projected to have a pH of 5.0.

    Would 2% Glycolic Acid be suitable?

    In my view exfoliation is always kinda irritation, no?

    Glycolic acid will not do much under high pH. What about enzymes (papain, bromelain)? They are usually used for sensitive skin or in summer products.

    @Nadeem

    Your best ingredients for this would be Polyhydroxy Acids: Gluconolactone, Mandelic Acid, Lactobionic Acid

    @MarkBroussard

    Do these acids cause the skin to be sensitive to sun light?

    Thanks @MarkBroussard
