What it is
Mexoryl SX, also called Ecamsule or Terephthalylidine Dicamphor Sulfonic Acid, is an ingredient developed and patented by L’Oreal.
What it does
Mexoryl SX is a synthetic sunscreen agent that protects against UVA rays, which can cause wrinkles and may contribute to skin cancer. It works by transforming UV radiation into heat.
Mexoryl SX is more stable than avonbenzone, but still degrades when exposed to the sun.
Side effects
Just like any other sunscreen agent, Mexoryl SX degrades when exposed to sunlight, so it’s necessary to reapply your sunscreen regularly, especially if you’re spending time outdoors.
In addition, Ecamsule doesn’t block the entire UV range, so it should be used in conjunction with other sunscreen ingredients to provide broad-spectrum protection.
Mexoryl SX can cause skin irritation and dermatitis in some people.

Before L’Oreal brought their moisturizers with Mexoryl to the U.S, people used to sneak some bottles in their luggage when they came back from France. I’ve never tried it as my skin does not love chemical sunscreens very much.

I use La Roche Posay’s Anthelios XL Spf 50+ every day on my forehead (for that famous post-pregnancy pigentation problem) and I’m quite satisfied with it, it doesn’t irritate my skin at all though I do have little bumps under the skin constantly because of the chemical filters and they just won’t budge! I suppose one has to make choices! Anyways, I highly recommend the sunscreen, I think Mexoryl is one of the most effective ingredients in protecting skin from sun damage. xx

Dao: lol, I can see why they did that, I probably would have too. :9
Anna: I’m glad that sunscreen works for you, bt it’s too bad the chemical filters give you bumps
Mexoryl SX is one of the best UVA absorbing sunscreen agent on the market. I prefer physical sunscreens but if I use a chemical one I always make sure it contains Mexoryl so that my skin is protected against UVA rays as well.
