This is the best product I have ever used on my skin and I tried a LOT of expansive brands. It helps with redness and overall skin tone. Please do not ever stop making this stuff... ...»

Really loving this product. I make the best Centella toner and most concentrated ever. 2 g of centella extract dissolved in 10g of alcohol(you have to stir a lot) plus 88 grams of water and you get a very concentrated toner. Creams, toners, ampoules... all have only 0,1% of triterpenes, this toner i make have 1,4%. I am loving it, will see the results. .. ...»

Just recently ordered this and LOVE! Green Tea EGCG truly is one of the most fantastic skincare actives out there. Very difficult to find good quality product (90%) and even harder to actually solubilize it! Love that it comes in pre-dissolved solution. I enjoy adding it at 1% (so 11% sol) to my serum formulations containing Niacinamide 5% + NAG 3%. Excellent for oily acne prone skin. *Only gripe... because the Pre-Dissolved Solution is SO heavy in propanediol (10 parts Propanediol for 1 part E.. ...»

The Pre-dissolved solution is excellent. Ferulic Acid is an amazing skincare ingredient (potent antioxidant, protects other sensitive antioxidants from light degradation, UV protection) but is absolutely ineffective if it isn't solubilized correctly. Makes adding to any Serum Base or w/o emulsion easy. Love using it (at 6%; so active 0.5%) with the Resveratrol Fluid (10%; active 1%) and Green Tea Extr for potent nighttime brightening treatment... ...»

I am following the moisturizing cream + Zinc dispersion recipe and I am extremely satisfied. I do allow for a little time for it to absorb in & then I dab off anything that I feel looks a little white - but that's because I initially use a fairly thick coating on myself. I use a bit of foundation at times on top and there are no issues as far as weird colors or texture issues. I am so grateful for this entire website as a one-stop-shop for such effective skin care products, and now we can.. ...»

This ingredient has done more for my skin than anything else I've ever used. I put it into a spray facial toner and use it morning and night. I noticed the effects immediately, they were that dramatic. I will use this forever, no question... ...»

Tinosorb M (Bisoctrizole)

Tinosorb M is the first UV filter to combine the two worlds of organic filters and micro fine inorganic pigments: it is a 50% aqueous dispersion of colorless microfine organic particles, which are less than 200nm in size and is dispersible in the water phase of an emulsion. Tinosorb M exhibits the widest UV absorption and delivers triple action: UV absorption due to the intrinsic photostable organic molecule, light scattering and reflection as a result of its microfine structure.

Key benefits of Tinsosorb M in skin care:

  • Can be incorporated in sunscreens, but also in day care products as well as
  • Large coverage of the UV-13 and UV-A range
  • Photostable
  • Ease of formulation
  • Less UV absorber required
  • Excellent compatibility with cosmetic ingredients and other UV filters
  • Ability to photostabilize other UV filters
  • Synergistic effect with UV-13 filters (SPF booster)

About Tinosorb M Bisoctrizole in DIY Skin Care

Tinosorb M is an innovative UV filter with a hybrid technology that combines organic filters with inorganic micro-fine pigments. It a water soluble ingredient that is added to sunscreens to provide additional UV absorption. Tinosorb M is presented as a 50% aqueous dispersion of less than 200nm micro-particles which can be easily incorporated in a sunscreen in the water phase of an emulsion. It has numerous advantages: easy to use, can be cold processed, efficient at low concentrations and contains no preservatives.

Recent research showed that a microfine organic-inorganic technology ensures enhanced SPF and UVR coverage, because the two components have a synergic effects [1]. Tinosorb M is acts both as an organic UV filter by absorbing the UV radiation and as an inorganic filter (due to the microfine pigment particles) deflecting the ultraviolet radiation [2].

Tinosorb M is very stable [3] and highly efficient in protecting against both UVA and UVB radiation   due to its triple action: UV absorption by a photostable organic molecule, light scattering and light reflection by its microfine structure. This enables Tinosorb M can absorb both UVA and UVB rays, providing a complete protection against the whole ultraviolet spectrum.

The active ingredient in Tinosorb M, Bisoctrizole is a broad-spectrum sunscreen that absorbs UVR and due to its microfine structure, with particles smaller than 200nm also reflects and scatters. Thus, Tinosorb M is able to succeed where other organic UV filters do not, especially in the UVB area. Research shows that formulations with Tinosorb M have efficiency comparable with zinc oxide (ZnO) and titanium dioxide (TiO2) [4].

Studies assessing bisoctrizole’s safety showed that when formulated into a sunscreen, bisoctrizole has minimal skin penetration, which makes it completely suitable for cutaneous use [5]. Also, unlike other chemical (organic) sunscreens, Tinosorb M is very stable when it comes to UVR photodegradation. Furthermore, bisoctrizole acts as a stabilizing agent for less stable compounds such as avobenzone [3]. Regarding the concern that like other organic UV filters, BASF’s Tinosorb product range may disturb the estrogenic balance, by interacting with the estrogen receptors, laboratory research showed that tinosorb products are safe. No estrogenic activity was registered [6]. Concluding, it can be said that Tinosorb is not only one of the most efficient sunscreen ingredient but also that it is very safe for use.
 
Note that some studies (by the same authors) indicate that Tinosorb M, containing decyl glucoside, is a frequent cause of allergic contact dermatitis.

We suggest that you start out with using a small percentage of this UV filter, test it first on the inside of your elbow for a period of time and, if there are no problems, gradually increase the amount (up to 10%).
