The Ordinary EUK 134 0.1% is a mimetic of superoxide dismutase & catalase, forming an exceptionally rare self-regenerating molecule that scavenges superoxide free radicals, eliminates hydrogen peroxide & converts reactive oxygen species into water & oxygen. While it has been around for many years, very few products on the market do use this truly superb antioxidant which can regenerate itself to offer round-the-clock antioxidant support. The only issue with EUK 134 is that it must not be used immediately with strong acids such as suspensions of Ascorbic Acid. Strong acids will completely destroy EUK 134 which is based on manganese. ...

With 7% Glycolic Acid, Amino Acids, Aloe Vera, Ginseng & Tasmanian Pepperberry. Glycolic Acid is an alpha hydroxyl acid that exfoliates the skin. This 7% toning solution offers mild exfoliation for enhanced skin radiance & visible clarity. The formula also improves the appearance of skin texture with continued use. This formula contains a studied Tasmanian Pepperberry derivative to help reduce irritation associated with acid use. This derivative is of plant origin & varies in colour seasonally & this colour variation may be apparent in the formula from time to time. The formula is further supported with inclusion of ginseng root & aloe vera for both visible radiance & soothing benefits. This p H of this formula is Approx. 3.6. Glycolic Acid has a p Ka of 3.6 & p Ka is the most important aspect to consider in formulating with acids. p Ka implies acid availability. When p Ka is close to p H, there is an ideal balance between salt & acidity, maximising effectiveness of the acid & reducing irritation. Higher p H numbers in such a case would increase salt which counter-intuitively would make the formula even more irritating than if the formula was more acidic. Alcohol-free, oil-free, silicone-free, nut-free, vegan, gluten-free, soy-free, cruelty-free. ...

The Ordinary Mandelic Acid 10% offers superficial dermal peeling that is gentler than other alpha hydroxy acids. The molecular weight of mandelic acid is 152.1 daltons which is larger than other alpha hydroxy acids (glycolic acid is 76.0 daltons, for example). This larger size allows mandelic acid to penetrate the skin more slowly which in turn makes it very gentle & suitable for all skin types including the most sensitive skin. You don't need a concentration of more than 10%, because then you would simply be achieving an indirect peeling strength that is more easily offered through lower percentages of glycolic acid. This formula is alcohol-free, oil-free, silicone-free, nut-free, gluten-free & vegan. The Ordinary is a cruelty-free brand; they do not test any of their products on animals. ...
