You often come across polyglutamic acid where moisture is involved. Behind the long name is a chain of many glutamic acid building blocks that can bind water. On the ingredients list it is called Polyglutamic Acid. It can appear in a formula together with hyaluronic acid. However, it is not possible to tell from the two names alone which serum will care for your skin more pleasantly. What else is in the bottle also counts.

An example is the Anua Niacinamide 10% + TXA 4% Serum : It combines polyglutamic acid with several forms of hyaluronic acid. The focus here is on niacinamide and tranexamic acid for the care of uneven skin tone. If you’re simply looking for a little more moisture, you don’t have to use this combination of active ingredients. Our brief knowledge of glycerin explains how a familiar moisture binder works in a cream.

If the Anua serum suits your routine needs, first distribute a few drops before the cream and increase the application carefully. Anua also recommends sun protection from SPF 30 during the day. By the way, the percentages in the product name refer to niacinamide and TXA. The proportion of polyglutamic acid is not stated.
