Neck wrinkles: Alpha hydroxy acids such as glycolic acid

Use these in whatever form suits you best, whether that be an exfoliating cleanser, an acid toner, a serum or a mask. Beta-hydroxy acid or polyhydroxy acids would work as well. Chemical exfoliation in this way is great for making skin look fresher, better hydrated, and glycolic acid in particular also boosts the skin’s collagen levels, improving its firmness.
