Vitamin C

Vitamin C is a normal skin constituent that is found at high levels in both the dermis and epidermis. The vitamin C content of the epidermis is higher than the dermis, although the vitamin C concentrations in both layers are approximately equal to that of other water-soluble antioxidants, including uric acid and glutathione. Aging, however, causes a decline in vitamin C content in both the epidermis and dermis. Excessive exposures to UV light or pollutants (e.g., cigarette smoke and ozone) may also lower vitamin C content, primarily in the epidermis.

Revitalize Aging Skin with Topical Vitamin C
Overexposure to ultraviolet radiation and environmental pollutants can accelerate skin aging by degrading collagen and triggering oxidative stress in the skin. Fortunately, the anti-aging benefits of a time-honored remedy used by ancient civilizations to heal their skin can help overcome these undesirable effects.

Vitamin C is an essential component in the body’s production of collagen and a potent antioxidant that can help rejuvenate aged and photodamaged skin.

While vitamin C is an important nutrient for overall health, little reaches the skin when orally ingested. As levels of vitamin C in the skin decline with age, replenishing levels directly in the skin can help combat collagen degradation and oxidative stress. Results from clinical trials show that when applied topically, vitamin C promotes collagen formation and mitigates the effects of free radicals, helping to maintain firm and youthful skin.

What makes topical vitamin C preparations so important? Humans and a few other species lack the ability to produce the vitamin C that is so vital for beautiful, healthy skin. To make things even more challenging, vitamin C is water-soluble. Consequently, a great deal of the vitamin C we ingest gets excreted rapidly.

While oral supplementation with vitamin C is important for maintaining one’s overall health, it is not very effective at increasing skin concentrations of vitamin C because its absorption is limited by active transport mechanisms in the gut. The most effective method for replenishing vitamin C in the skin is therefore to go straight to the source, and apply it directly to the skin.

Topical antioxidants produce much higher concentrations in the skin than nutritional supplements. In fact, applying vitamin C to the skin is 20 times more effective than oral ingestion. Simply applying vitamin C daily for three days can achieve optimal levels in the skin. It is also known that once a topical antioxidant is absorbed into the skin, it cannot be washed or rubbed off. So, even after stopping application, significant amounts of vitamin C will remain in the skin for up to three days.

Rejuvenating the skin by constantly replenishing vitamin C stores can therefore help maintain healthy, younger-looking skin, especially as we get older.

When incorporated into your daily skincare lineup, well-formulated products containing vitamin C can provide a range of benefits that keep your skin younger-looking, longer! See what C can do:

Reduce the appearance of brown spots and other types of sun damage
Helps boost healthy collagen production (hello, firmer skin!)
Reduce inflammation and irritation, both of which cause a cascade of damage
Fade post-breakout red marks by improving skin’s natural healing response
Increase the effectiveness of your sunscreens and boosts your skins defense against UV exposure
