Ingredients higher up in an ingredient list are typically present in a larger amount. Helianthus Annuus Seed Wax is created from the common sunflower. Sunflower seed wax is made up of long chain non-glyceride esters, a small amount of fatty alcohols, and fatty acids. This ingredient is often used to enhance the texture of products. The fatty acid properties also help hydrate the skin. Tocopherol is a fat-soluble antioxidant known as Vitamin E. You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells. Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes. It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks. This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage. This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there. In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading. Concentrations usually range from 0.1-1% in most leave-on products.
