These three Skinceuticals serums are all ideal for sensitive skin, include skin afflicted with chronic conditions such as eczema and rosacea. They function by way of a patented formula that combines ferulic and L-ascorbic acid incorporating newly developed AOX+ chemical technology. So just how does this new patented formulation work to benefit the skin?
Skinceuticals Serum Neutralizes Oxidants (Free Radicals)

Ascorbate even on its own in its free state is a powerful antioxidant that functions by being available for molecularly optimal oxidation. You see, a high percentage of oxidants contain an unpaired electron in their outer molecular shell. The result is that they are highly reactive and far more damaging to living tissues on a molecular level.
A Missing Electron Creates An Open Slot On the Oxidant Ion
The best way to visualize it, is that these highly reactive oxidants (free radicals) have a missing electron that creates an open slot on the outside of the atom or “ion”. This vacant slot makes it far more easy for the atom of oxidant to attach itself to another atom in living skin tissue. Rust or “iron oxide” is the result of steel being oxidized, so when your living skin cells are oxidized they in a way “rust.”
Like a Square Peg and a Square Hole

Now the ascorbate ion contained in L-ascorbic acid is also highly reactive. Only its reactive in such a way that it seeks out oxidants and most particularly highly reactive oxidants (free radicals). Like a square peg and a square hole, when they find each other the ascorbate ion plugs readily into the “electron slot” in the oxidant that made it so dangerous to living tissues. Once they combine they are instantly neutralized and converted to mostly water.
Skinceuticals Serum Stops Skin Cells From “Rusting”
Skinceuticals serum 10-15 and 20 AOX+ are all chemically engineered to penetrate the skin immediately up application and go directly to work below the skins epidermal layer attacking and neutralizing free radicals. Its important to remember that unless highly reactive free radicals are neutralized in this way chemically, they will eventually latch onto and oxidize or “rust” molecules contained in living skin tissues.
There are several active ingredients that are used in combination to create remarkable anti-aging skin care products. Countless different product brands claim that they use the best mixture of ingredients to make a powerful solution. Each product promises unmatched protection as well as noticeable results against damaged skin. However, a number of these products fall short of their marketing claims and leave numerous people disappointed with the results they once see. SkinCeuticals is a top skin care product brand that uses scientifically formulated products in order to give consumers desired results and protection. Among one of the leading products they offer is the SkinCeuticals Serum 20.
