How Does It Work?

Vitamin C is a powerful ingredient that offers multiple skincare benefits, especially when applied directly to the source. As the human body is unable to produce this vitamin—and most people receive it primarily in a liquid form, which exits the body quickly—topical treatments are the most effective ways to absorb the ingredient.

Once applied to the face, this product will replenish the skin with vitamin C, which helps boost the synthesis of collagen. About 75% of the skin is made up of collagen protein; but as we age, our bodies naturally slow its production.

By equipping your skin with vitamin C, this ingredient can influence the enzymes responsible for collagen synthesis, to support healthier and younger looking skin.

In addition to collagen production, Obagi’s expert elixir is also able to reverse damages done by free radicals. Free radicals are essentially uncharged molecules with unpaired electrons that cause damage to your skin’s cells.

Free radicals are typically caused by environmental stressors, like pollution and cigarette smoke. These molecules result in damage to your skin when they steal an electron from your body’s collagen protein, causing your skin to look aged, discolored, and lose its form.

Obagi vitamin C serum can combat these oxidative damages, due to the high concentration of antioxidants, which are electron lenders.

Not only will this product help protect your skin’s collagen and boost its production, but their specialized formula will help your skin retain its moisture by hydrating and rejuvenating your face. The propylene glycol found in Obagi, allows the product to deeply penetrate the skin so that it can act to combat deep fine lines and damages from within.

Obagi’s highly hydrating formula promotes plump and soft skin while enhancing its health, firmness, and strength.

The benefits are certainly outstanding, just read up on Obagi C serum reviews and you’ll know what I’m talking about.

How Effective is it?
