Vitamin C from food boosts collagen levels in skin

A new study has found that collagen production and skin renewal directly respond to the amount of vitamin C we eat. The study shows that skin vitamin C levels are closely tied to levels of the vitamin in the blood (plasma) and can be boosted by increasing fruit intake. Carried out on two dozen healthy adults, the study shows that boosting plasma levels by consuming two vitamin C-rich kiwifruit per day increases the amount of the vitamin in the skin, improving skin thickness (collagen production) and stimulating renewal and regeneration of the outer skin layer. Professor Vissers says, "We are...
