Latest discovery says that evidence is found to strengthen the potential role of certain vitamins to reverse aging caused by sun damage to skin. And Vitamin A, C, E and B3 are most important for that.
There are many products available in market containing those vitamins, which can be effecting to reverse the aging process and treat the sun damage, however up to which extent is not yet discovered.
Vitamins have antioxidant properties that contribute to prevention of anti-aging. Though it is proved that vitamins can play this role to reverse the sun damage, it is not yet proved whether skin-care products found in the market can be effective for the same.
To protect the skin from UV rays, vitamin A can play substantial role. There is widespread evidence that topical retinoids (made up of retinol) can successfully treat skin that has been marred by the aging process. Carotenoids, on the other hand, weren’t shown to be beneficial in treating sun-damaged skin but they may play a role in protecting the skin from the effects of aging.
Retinoids including tretinoin cream and tazarotene cream, are already approved by the U.S. Food and Drug Administration as appropriate remedies for fine wrinkles, roughness of the skin and spots caused by too much exposure to the sun and aging, according to Kim. Other retinoids have also proven effective in making small wrinkles disappear, she said.
Vitamin B3 was also looked at for its role in battling skin damage from aging and the sun. It was found to increase collagen production, reduce wrinkles, decrease dark spots and improve skin elasticity in clinical studies, according to Kim, but she said larger clinical trials were needed to confirm that B3 is a good treatment for aging caused by UV damage.
“Consumers should understand from our study that skin care products with vitamins may not provide clinically meaningful improvement,” she added. “What is known is that proper sun protection is key to the prevention of photoaging and should be top of mind at all times.”
