NeoStrata Targeted Treatment Sheer Physical Protection SPF50, 50 ml

Product Information

This mineral sunscreen with iron oxide from Cotz is light-weight, silky, blends well, and leaves a sheer matte finish. It provides a subtle tint that blends in with all skin tones and is water resistant for up to an hour! It’s non-greasy and suitable for both oily skin types as well as sensitive skin. The coverage may not be enough to replace your foundation, but it would make an excellent primer. In addition, the tinted colour is light enough for fair skin. Sunscreen should be at least SPF30 – while there isn’t a huge amount of additional UVB protection offered by SPF50+ sunscreens (SPF30 protects against 97% of UVB rays, while SPF50 protects against 98% of UVB rays), there may be better UVA protection in higher SPFs. This is due to the PPD method that recommends a UVA:UVB ratio of 1:3. As for the disadvantages, Zinc Oxide is also not cosmetically elegant. It leaves a disturbing whitish tint on the skin , although , according to a 2000research paper by Dr. Pinnell, it's slightlyless white than TiO2. Still, it's white and disturbing enough to use Zinc Oxide nanoparticles more and more often. Most people will find no issues with sulfate, however if you find your skin doesn't like sulfates then free feel to avoid them by looking out for the sulfate-free icon on Skincarisma.

There are two main ways that research suggests we can protect our skin from visible light – iron oxide and antioxidants. Iron Oxide Castanedo-Cazares, J., Hernandez-Blanco, D., Carlos-Ortega, B., Fuentes-Ahumada, C. & Torres-Alvarez, B. (2013). ‘Near visible light and UV photoprotection in the treatment of melasma: a double-blind randomized trial’, Photodermatology, Photoimmunology & Photomedicine, 30(1), 35-42. Note: Due to iron oxides natural reddish hue, the majority (if not all) of sunscreens containing iron oxide will be tinted. Some research suggests that the addition of iron oxide to mineral sunscreens can reduce the amount of UVA and visible light transmitted to the skin to 20%. In particular, when iron oxide is combined with zinc oxide, it can reduce the amount of UVA radiation transmitted to the skin to 1.5% [3]. Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.A moisturizer, sunscreen, and foundation in one? This light-weight mineral sunscreen with iron oxide has the benefit of added antioxidants to protect against free radical damage, hyaluronic acid to improve skin hydration, and is available in three different shades. It’s suitable for all skin types and tones. However, it loses a few points for only offering SPF 20 protection. Gluconolactone: a Polyhydroxy Acid (PHA) that is found naturally in the skin and provides antiaging and gentle exfoliating benefits without sun sensitivity. It is a welcome choice for sensitive skin types as it strengthens the skin’s moisture barrier leaving it more resilient, while also providing potent antioxidant benefits. The disadvantage of Titanium Dioxide is that it's not cosmetically elegant, meaning it's a white, "unspreadable" mess. Sunscreens containing Titanium Dioxideare often hard to spread on the skin and they leave a disturbing whitishtint. The cosmetic industry is, of course, really trying to solve this problemand the best solution so far is using nanoparticles. The itsy-bitsy Nano-sized particles improveboth spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns. They help loosen up the dirt and grime from your skin and hair to allow for water to wash it away with ease.

Chemical free, oil free, paraben free, and fragrance-free, this mineral sunscreen with iron oxide is water resistant for up to 80 minutes. This sunscreen is excellent for skin that suffers from rosacea or melasma. It’s non-greasy formula also makes it a great option for oily skin types as well as dry and sensitive skin types. The tinted colour may be too dark for fairer skin types. NeoStrata® Sheer Physical Protection SPF 50 is an ultra-sheer, physical broad-spectrum sunscreen that provides protection from UV radiation and DNA damage. A sheer universal tint blends with the skin’s natural tone providing an ultra-sheer mattifying finish. Suitable for all skin types including sensitive skin. In general, mineral sunscreen ingredients zinc oxide and titanium dioxide are better at protecting the skin from visible light than chemical sunscreens due to the fact that they reflect and scatter light [4]. In one study, the addition of antioxidants to a sunscreen led to a 78% reduction in the number of free radicals produced after irradiation with visible light. Even more impressive, antioxidants alone reduced the amount of free radical damage in a similar way [6].However, they still do not offer sufficient visible light protection without the addition of iron oxide. UV radiation leads to the production of DNA-damaging free radicals in the skin, decreases collagen and elastin levels within the skin, and causes changes to skin pigmentation. While iron oxide is effective at absorbing all wavelengths of visible light [4], it is particularly effective at absorbing longer UVA radiation and blue light but its effects are less optimal as wavelengths increase [5]. UVA and Blue light (high energy visible – HEV – light) are particularly damaging for skin and adequate protection is not offered from conventional sunscreens [2]. However some sulfates are so good at their job, they can wash off your skin’s own natural oils that keep it moisturised and protected which can lead to dryness and irritation.

If not, don't worry about it - they do have had one of the longest safety records as preservatives! Lactobionic Acid: part of the Polyhydroxy Acid (PHA) family and is derived from natural sugars. It helps to reduce the appearance of lines and wrinkles, discoloration, enlarged pores and roughness through gentle exfoliation, while also attracting moisture for added hydration and comfort. While UV radiation is the most damaging form of solar radiation for the skin, it only accounts for a small percentage of total solar radiation.

So why are we not protecting our skin against visible light? And, more to the point, how can we protect our skin against visible light? How To Protect Skin Against Visible Light?

Antioxidants protect against visible light in the same way they help protect against UV radiation – by preventing or reducing the production of DNA-damaging free radicals in the skin.There's still a lot of support for avoiding parabens following the better safe than sorry route.
