Anhydrous Vitamin C Cream

Vitamin C is an essential nutrient not just for humans but for other living organisms as well. It is a popular antioxidant that protects the body against oxidative stress. Some physiological functions that benefit from vitamin C intake include collagen synthesis, carnitine production, microsome metabolism, tyrosine catabolism, and neurotransmitter synthesis. This facial cream recipe is especially formulated with this ubiquitous vitamin to protect your skin against the ravages of the sun and the damages of free radicals. Massage it on your face before going out and before going to bed for a healthy, ruddy glow!
