Vitamin C and the biochemical part it plays in the synthesis of collagen makes it a indispensable part of skin health. Many years of scientific study of dietary and topical vitamin C serum clearly shows how skin cells benefit. Despite all the research, the picture of vitamin C and its many roles with skin is not completely clear.
2 Vitamin C Skin Content Killers Impossible to Avoid
Vitamin C is a known to be a chemical building block of skin, and therefore a part of the different types of skin layers. This vitamin exists in abundance in the dermis and epidermis skin layers; although it is found in greater amount in the epidermis which is the outer skin layer. Furthermore, vitamin C is a water-soluble antioxidant and the its concentration is roughly the same as other antioxidants found in the skin.
The age-old problem: The problem is the concentration of vitamin C declines with age. And this decrease occurs in both the dermis and epidermis. But things get worse and there's no escape from it.
Environmental factors, and there's a laundry list of them, also contribute to further decrease in vitamin C in the skin. Too much UV exposure and all the various types of pollutants are the culprits. And it's the vitamin C in the epidermis that suffers the most. That makes perfect sense, though, since the outer skin layer is the first line of defense against environmental pollution.
Topical Vitamin C Skin Serum Picks-up Where Dietary Stops
The normal method of vitamin C delivery to the skin is via the bloodstream. Ascorbic acid, a form of vitamin C, is carried by transport proteins that are specific for that type of vitamin C. These special proteins exist in all skin cells in every skin layer. Here's something interesting and peculiar about the epidermis.
The outer skin layer, the epidermis, is not as rich in blood transport ability as deeper skin layers. In other words, the vascular density is lower – fewer blood vessels and capillaries, or much smaller blood vessels.
There are important implications here for the ability of epidermal skin cells to get vital vitamin C they need. And that's why topical vitamin C skin serum compensates so well. Keep in mind that vitamin C levels are constantly under attack from external pollutants; then there's the age factor.
But what about taking vitamin C supplements; do they help?
Of course orally ingested supplements can help along with dietary vitamin C sources. But they are limited and here's why.
Oral supplements of vitamin C do increase the amount of vitamin C in skin cells. The issue is that bloodstream levels of vitamin C eventually become saturated. That means the bloodstream can only hold so much vitamin C. When this saturation level is reached, the amount of vitamin C in the skin cells and skin layers cannot increase.
The result is there is a finite degree of anti-aging benefits when the only source of vitamin C for the skin is via oral ingestion. Once again, ascorbic acid serum applied topically mitigates the problem of saturated serum vitamin C.
One has to ask and consider that many people very likely do not have saturated levels of bloodstream vitamin C. The only way for that to occur is through the diet, vitamin C supplementation or a combination of the two.
It's a game of pluses and minuses because external pollutants and age-related factors are constantly fighting to reduce vitamin C in skin cells.
