Vitamin A derived skin care products can be found in many anti-aging beauty formulas. The antioxidant effect of vitamin A helps rejuvenate the skin from deep down within the collagen fibres working hard to reverse damages caused by free radicals from sun damage, smoking and other environmental factors.
Keep in mind that excessive vitamin A is not excreted like vitamin C or B. Vitamin A Is a fat soluble vitamin meaning that it is stored in the body. Eating a couple of carrots is not going to hurt. Natural sources of beta carotine is not converted to vitamin A until until your body converts it when necessary. Synthetic man-made vitamin A such as Tretinoin is a different story. Large doses can become toxic and in some cases lethal.
