In addition to the white cast of mineral sunscreens, they often do not play well when layered with makeup on top. They can be used alone or combined with chemical filters to create a very high SPF that is lighter and less occlusive than a pure mineral sunscreen. Mineral sunscreens are growing in popularity and are preferred by those seeking to avoid a long list of chemicals, some of them on our list of skin care nasties to watch out for. Often referred to as Transparent Zinc, the particles are micronised into nano-particles, which is what makes them transparent, but these too are not totally without their share of scrutiny and concern. The best formulations use a new generation form that is less thick and less sticky on the skin. Zinc Oxide is less whitening than Titanium Dioxide and offers excellent UVB and UVA protection. Despite some concerns, there is little evidence that Titanium Dioxide or Zinc Oxide can penetrate the skin to enter our bodies. Given the dreaded ‘white cast’ that most people so dislike, sunscreen makers are increasingly opting for nanoparticle versions, and the US Environmental Working Group (EWG) has urged manufacturers to use “forms of minerals that are coated with inert chemicals to reduce photoactivity”. The most commonly used mineral filters are Titanium Dioxide and Zinc Oxide, which come from rocks that are ground into very fine particles. They use mineral filters that sit on the surface of the skin and block and scatter UV rays. Mineral sunscreens work in a different way to chemical sunscreens. Read on to find out about what you need to know about sunscreen ingredients and which sunscreen ingredients it may be best to avoid. Visit our pages on Skin Care Ingredients, Fragrance in Skin Care, Essential Oils in Skin Care to find out more. Also watch out for other potentially harmful and irritating ingredients, such as Retinyl Palmitate, Fragrance and Essential Oils. Carefully check all sunscreen ingredients used in the formulation, including the active ingredients and the non-active ingredients. When choosing a sunscreen, most people will ensure offers UVB and UVA protection, but do not look any further. By incorporating antioxidants into your skin care routine, you can enhance the effectiveness of your sunscreen and better fight the damaging effects of the UV rays that do get through. It is also important to be aware that the maximum protection an SPF30 can give you against UVB rays is 97%. The SPF on a product is the level of protection the product provides against UVB rays it does not indicate what protection you are getting against UVA rays. Prevention is still the best anti-ageing skin product there is. This makes sunscreen a key part of any skin care routine.Įveryone, no matter what their skin condition or skin care goals, needs a great sunscreen that offers full UVB and UVA protection. UVA rays also penetrate glass, so being indoors may not be protective. This leads to direct damage to DNA and a loss of Retinoic Acid (Vitamin A) in our skin. While UVB rays burn the skin, UVA rays penetrate more deeply and play a significant role in accelerating skin ageing by doing damage to basal skin cells and melanocytes. Most of us are exposed to some level of UVB and UVA rays each day, and even small amounts of daily exposure can prove damaging to our skin over the long term. Sunscreens are one of the most important products we can apply to our skin, so it is worth taking the time to get to know your sunscreen ingredients, how they protect your skin and how to choose the right filters, whether mineral or chemical. We assume that all sunscreen ingredients are equally safe and so do not consider whether some are best avoided. Yet many of us like to skimp on how much we spend on sunscreen while happily going overboard on other skin care products. There is a reason why you keep hearing about the need for sun protection every day: it matters! The sun is the leading cause of skin damage, including premature skin ageing, irreversible damage to the skin’s DNA and a higher risk of skin cancer.
