Most of what we wrote about Titanium Dioxide is also true for Zinc Oxide so we will focus here on the differences. A silicone-based, chemical sunscreen agent that protects the skin in the UVB range (290-320 nm) with a peak absorbance at 312 nm. A bit of a sloppy ingredient name as it covers not one but three pigments: red, yellow and black iron oxide. The itsy-bitsy Nano-sized particles improve both spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns. Third, THDA seems to have all three magic abilities of pure vitamin C: it gives antioxidant protection from both UVB and UVA rays, it increases collagen synthesis (even more than AA) and it has a skin brightening effect by reducing melanogenesis by more than 80% in human melanoma cell cultures.
As for skincare, it makes the skin silky smooth, creates a subtle gloss and forms a protective barrier (aka occlusive). Guided by her vision, UV Skinz has grown to represent a life full of freedom, peace of mind and sun-filled adventure. Whether it’s our Mineral Crème SPF 50 or our Quick Dry Body Spray SPF 40, we make sunscreen that leaves your skin soft and smooth. It is a polymer (created from repeating subunits) molecule and has different molecular weight and thus different viscosity versions from water-light to thick liquid. Regular sized Titanium Dioxide also has a great safety profile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters).In addition, vitamin C's three magic properties (antioxidant, collagen booster, skin brightener) are all properly proven in-vivo (on real people), but for the derivatives, it's mostly in-vitro studies or in the case of THDA, it's in-vitro and done by an ingredient supplier. MDSolarSciencesTM is a collection of Dermatologist- Developed clean, natural and sustainable SPF Skin Care formulas that people love to wear every day. The coating helps to stabilize pigments in the formulas and also helps them to spread easily and evenly on the skin. A high-molecular-weight silicone elastomer (rubber-like elastic material) that is usually blended with a base silicone fluid (such as dimethicone or cyclopentasiloxane) to give the formula a silky smooth feel and to act as a thickening agent. Friedman, the products are top-rated by the Environmental Working Group (EWG), completely non-toxic, cruelty-free and reef-safe.
It’s a nice ingredient that just feels good on the skin, is super well tolerated by every skin type and easy to formulate with. You need not worry about UVA-UVB light, the added Titanium dioxide and Zinc Oxide minerals are what shields your skin against these harmful lights! So in theory if you’re wearing SPF 30 that means it would take 30 times longer to burn than if you were not using sunscreen.It can solubilize some commonly used UV-filters like Oxybenzone or Avobenzone and it can also help to increase the SPF rating of sunscreens. Oh, and according to Wikipedia, it even helps to stabilize famously unstable UVA-filter, Avobenzone. Depending on your hair type, it can be a bit difficult to wash out and might cause some build-up (btw, this is not true to all silicones, only the non-volatile types). We never use oxybenzone or octinoxate - two ingredients known to irritate skin and impact marine life.
But the really impressive thing about it is the lack of chalky white finish that we’re accustomed to with mineral sunscreens (it only left a faint cast on our tester who identified as Fitzpatrick skin scale type VI). And, if you’d like a dash a color for an outdoor dinner date or day outing, try our Hydrating Sheer Lip Balms with SPF 30, available in 3 universal shades. After applying, we rated each product for the following criteria: ease of application, feel, finish and scent on a scale of 1 (poor) to 5 (excellent). Naturally derived and safer Eco-cert zinc oxide help reduce the risk of photo aging and skin cancer, while Vitamin C and natural antioxidants (like Green Tea, Cranberry Fruit and Pomegranate Extracts) fight sun damage and free radicals.For more information about our SPF formulas and how they fit in a skincare routine, check out this blog. The MDSolarSciences Mineral Moisture Defense SPF 50 sunscreen nabbed the best overall spot for its . The main concern with nanoparticles is that they are so tiny that they are absorbed into the skin more than we want them (ideally sunscreen should remain on the surface of the skin). In addition to our Mineral-based crèmes and lotions with varying SPF levels, with comfortable textures, our Quick Dry Body Spray SPF 40 is a popular favorite. Like the other MDSolarSciences sunscreens, Mineral Moisture Defense provides stellar and very water resistant sun protection, thanks to a combination of zinc oxide and titanium dioxide.
