The beauty industry has promoted the use of Vitamin C and E for years. Both vitamin C and E stimulate collagen production and vitamin E fights free radicals. These ingredients are used in many high-quality skin care products. CBD is rich in both Vitamin C and vitamin E. Of course, the quality of all these ingredients is critical. Look for quality ingredients with labels that indicate no artificial chemicals have been used. It is also good to confirm the products were manufactured in the USA. Much of the CBD manufactured outside of the US is unregulated and may have contaminants.
