Clothing provides up to 98% UV protection against harmful UV rays. Choose tightly-woven fabric over loosely-woven types for the best UV shield. Test the UV-protection level of the fabric by holding it up to the light. If you can see through the fabric, then the UV radiation can penetrate it easily to reach your skin layers. Taking antioxidants can help boost your sun protection from within. Coenzyme Q10 is an essential nutrient and potent antioxidant to fight UV-generated free radicals, and also safeguards your heart and enhances energy levels.
