Is Tinosorb M The Perfect UV Filter?

Tinosorb M is a synthetic UV filter that comes in the form of nanoparticles (but, don’t worry, they don’t penetrate skin).


As of now, Tinosorb M is used in Europe, Asia, and Australia. But it’s still banned in the US (this has more to do with the FDA’s lengthy UV process approval than any real dangers with Tinosorb M).

It’s a shame because Tinosorb M has a better texture than mineral filters (like Zinc Oxide) and is gentler than traditional synthetic filters (like Oxybenzone).

 P. S. You won’t find Tinosorb M on the label. It hides under the names “Methylene Bis-Benzotriazolyl Tetramethylbutylphenol” or Bisoctrizole.


What Does Tinosorb M Do In Skincare Products?

Tinosorb M is a UV filter on steroids.Most UV filters only protect you from UVA or UVB rays. 

Tinosorb M does double duty: it provides broad spectrum protection, keeping you safe from UVA (both UVA-1 and UVA-2), UVB.


Like mineral filters Titanium Dioxide and Zinc Oxide, Tinosorb M works in two ways:


It absorbs UV rays and transforms them into a less damaging form of energy (heat)When UV rays hit your skin, it reflects and scatters them away from it, so they can’t damage it

There are not many UV filters that can give you this level of protection.


Is Tinosorb M Stable?

Some UV filters (I’m looking at you, Avobenzone) degrade and slowly stop working when exposed to sunlight. They literally get used up on the job.


Tinosorb M is stable even when exposed to sunlight. Plus, it helps other UV filters degrade more slowly.

Is Tinosorb M Safe?

As far as we know, yes. Here’s what I mean.


Tinosorb M is a pretty new UV filter, so we don’t have data on its long-term safety. It just hasn’t been around long enough for scientists to do this type of research. But, so far, we have no reason to believe it poses any dangers.


For starters, it doesn’t significantly absorb into your skin (contrary to popular opinion, very few substances make it through its protective barrier). If it can’t get in, the worst it can do is give you a bad rash. But this is rare.
