I can't reiterate enough the importance of wearing sunscreen on a daily basis. In May of 1999 the FDA published a monograph listing 16 approved sunscreen agents. Only 2 were inorganic (physical) ingredients and 14 were organic agents (chemical).
Inorganic agents physically reflect and scatter UV rays. They have a broader range of UV protection because they are physical UV blockers. In order to improve the aesthetics and use of these ingredients they have been micronized (nanotechnology) into a small molecules. Recent studies indicate the micronized zinc oxide is superior ingredient.
Organic sunscreen ingredients act like UV sponges to absorb the damaging rays. When an organic sunscreen ingredient absorbs UV rays it neutralizes UV damage preventing skin cancer and photo-aging. This depletes the amount of sunscreen available for protection and is the reason reapplication of your sunscreen is indicated. UVA organic filters include cinnamates, benzophenones, and others. Some organic sunscreen ingredients are more stable than others. This is the main reason why some sunscreens are better than others.
One of the best facial sunscreens for daily use is Rx Systems PF's New Facial Moisturize with SPF 35. It contains translucent, micronized zinc oxide, octyl methoxycinnamate, octocrylene, and oxybenzone. Combination sunscreen ingredients have been shown to be more effective than single agent sunscreens. In addition, antioxidants were added to the Facial Moisturizer SPF35. They include Vitamin E (tocopherol) and vanilla planifolia (vanilla bean). This enhances the sunscreen protection and provides additional photo-damage repair when sunscreens fail. This accommodates the need for a daily, all year round sunscreen that provides protection from UVB and UVA rays. Don’t reserve sun protection for only sunny days.
