Cosmetics Formulation Development

Lactic Acid (AHA) Neutralized Use 5% in products to nourish the body, focus on white, reduce marks. 1 Can I use it during the day or should I avoid the sun? 2 Can I put it in the serum? Do I have to use an acid-tolerant body building agent? Please give me some advice.

Hello. The neutralize type has less exfoliation efficiency than the acid type. It can be used during the day as usual. The formula has to be electrolyte and acid resistant. Try adding it first. If the cream is less liquid, adjust the recipe and use a helper such as ThixoGel™ , Xanthan Gum
