Allies of Skin 20% Vitamin C Brighten + Firm Serum: 20% Ethylated L-Ascorbic Acid + Orange Extract Complex with Glutathione. Firms & Intensely Brightens. For Smooth, Elastic Skin 1 oz / 30 ml

Nice hydrating serum. Expensive but feels very moisturising

Lo compré por el precio ya que el producto es mucho más caro en su web, cierto que una vez aplicado no deja ningún residuo pero es muy denso y cuesta un poco aplicarlo. Por lo demás la calidad es de Allis of Skin, no defrauda.

I got this when it was $88 au. Steal! Love Amazon.

This Allies of Skin 20% Vitamin C Brighten + Firm Serum is is a milky white color. It has an oily/heavy and slightly sticky texture that takes some time to absorb, but if you can tolerate the texture and potency, it's very effective. It does not contain added added fragrance. The key active ingredient is 3-O-Ethyl Ascorbic Acid, which is a more stable derivative of pure vitamin C (ascorbic acid) that offers the same anti-aging benefits. Vitamin C is an antioxidant, and has brightening effects because it stimulates collagen production. There's also gluconolactone, an effective exfoliant, in the ingredients as well. It is packaged in an opaque tangerine orange bottle, which is good because Vitamin C deteriorates and becomes less effective with exposure to both light and air/oxygen. It's also dispensed with a pump dispenser, which is ideal, since reducing air exposure keeps the product fresh for longer. Allies of Skin is a prestige brand and its actives are potent, so use with care. Vitamin C is potential irritant for sensitive skin, so always patch test before using liberally on the face. It's made in the USA. The expiration date is years out and clearly marked on both the bottom of the bottle and the bottom of the outer box. The PAO is 12 months. The ingredients are: Propanediol, Glycerin, 3-O-Ethyl Ascorbic Acid, Benzimidazole Diamond Amidoethyl Urea Carbamoyl Propyl Polymethylsilsesquioxane, Dimethyl Isosorbide, Sunflower Seed Wax, Polyglyceryl-10 Tristearate, Ethoxydiglycol, Dicaprylyl Ether, Water, Caprylyl Glycol, Bitter Orange Culture Extract, Glutathione, Acetyl Cysteine, Dimethylmethoxy Chromanol, Ergothioneine, Tocopherol, Gluconolactone, Radish Root Ferment Filtrate, Xanthan Gum, Silica, Sodium Benzoate, Calcium Gluconate

This is a very nice piece of art. The result is immediate because its visous. In my opinion after 30 yrs in the beauty business, this is a gem

My favorite c vitamin serum! I think it’s genious that the vitamin c activates when mixed with a water based serum
