The devil is in the details so the thing you should pay attention to is the concentration of vitamin C in a formula. REN Keep Young And Beautiful™ Firming And Smoothing Serum contains hexapeptide 11 from yeast fermentation to help improve skin firmness. When preserved in serum form, it should come as a clear liquid. It should be stored in a dark bottle to minimise light exposure. The opening should be airtight. You’ll often see this power ingredient infused in serums, moisturisers, cleansers and even in powder form. It’s adaptable enough to be worked into different formulas and concentrations. The most effective topical form of vitamin C, though, is called L-Ascorbic acid. Why should you use a vitamin C serum? Katisha D. Game changer in skincare! Great products.
