Why Tinosorb M And Tinosorb S Are Effective
Historically, sunscreens have been used to prevent sunburns. These sunscreens were formulated primarily to protect the skin from UVB rays which cause burns. We’re aware now, that UVA rays, in addition to UVB rays are problematic. UVA rays can cause cellular damage under the dermis. This damage can lead to wrinkles, skin sagging, age spots and some types of skin cancers.
Sunscreens formulated with Tinosorb provide substantial broad spectrum protection from both UVA and UVB rays. Available as Tinosorb M and Tinosorb S, these ingredients work to absorb, scatter and reflect the sun’s UV rays. Below, you’ll learn why sunscreens that contain these 2 active ingredients are so effective in protecting your skin from the sun.
Tinosorb S Is Photostable
Tinosorb S (also called Bemotrizinol) is an oil soluble ingredient that is capable of absorbing UVA and UVB rays, resulting in broad UV spectrum protection for the skin. One of the benefits of Tinosorb S is that it is a photostable compound. When combined with other sunscreen ingredients, it helps to avert molecule degradation caused by the photons present in the sun’s UV rays. This photostability enhances the sunscreen’s effectiveness in protecting the skin.
Tinosorb M Provides Stabilization
Tinosorb M (also called Bisoctrizole) is a water soluble ingredient that is added to sunscreens to provide additional UV absorption. Like Tinosorb S, this ingredient can absorb both UVA and UVB rays. It also stabilizes other sunscreen compounds that absorb UV rays. This organic ingredient uses a unique blend of particulates to offer 3 powerful actions. By absorbing, reflecting and scattering the sun’s UV rays, Tinosorb M provides high-level broad spectrum coverage of UVA and UVB rays. It is also naturally stable and not susceptible to significant photodegradation (degradation upon exposure to sunlight).
Complementary UV Absorption And Reflection
When used together, Tinosorb S and Tinosorb M provide coverage across a wide spectrum of UV radiation. Sunscreens that include both active ingredients can protect the skin by acting as a filtering agent for UVA and UVB rays. The ability of Tinosorb S to absorb UV rays while preventing the photodegradation of other ingredients complements the triple-action qualities of Tinosorb M (absorbing, scattering and reflecting UVA and UVB rays).
Effective Tinosorb Sunscreens
The high efficiency and complementary qualities of Tinosorb S and Tinosorb M provide concentrated protection from broadband UV radiation. For those who have ultra-sensitive skin that is sun-intolerant, the following Tinosorb sunscreens should be considered:
- Bioderma Photoderm Max SPF 50+ Lait for Face and Body – contains both Tinosorb S and Tinosorb M. Can be used on pale skin and provides maximum protection from the sun’s intense UV rays. It’s especially useful in extreme conditions such as the mountains or tropics.
- Bioderma Photoderm Max Fluide SPF 50+ for Face – a lighter textured formulation than the lait which contains both Tinosorb S and Tinosorb M. It’s formulated to be used on skin that is particularly sensitive to sun exposure.
- Avene Creme SPF 50+ – with Tinosorb M and Tinosorb S to deliver high UVA and UVB protection for sensitive dry to very dry skin types.
Tinosorb sunscreens will shield skin that is naturally intolerant to the sun’s intensity (including pale and freckled skin). If your skin is sensitive, try the sunscreens recommended above for maximum protection.
