Cryo-Flash Cream-Mask.

"The Clarins Cryo-Flash Cream-Mask is a 10-minute icy cold gel cream face mask. Its highlighted ingredients include MGA, a menthol derivative, organic evening primrose extract, and horse chestnut essence. I find menthol a little bit irritating to my skin, so this probably wouldn't be one for me. It seems like a brightening mask, especially for circulation, but I think it would be a little bit too intense for people with sensitive skin."

"Whilst the mentholy cold thing might be a bit more of a gimmick, it may be down more to the actual ingredients within the mask that help with the lifting, the firming, whatever it is that they're claiming affects. Menthol, whilst it can be irritating in some ways, I believe the way it's formulated into this particular product is more just a cooling sensation and even anti-inflammatory. This is a nice luxury to have. I wouldn't say I will keep buying it to cool down my skin, seeing as I do know my moisturizers do just as good a job. Even like a cold mask in the fridge, even just a sheet mask straight out the pack also cools down my skin. This gives you that kind of placebo effect, because you feel it as well. You're like, oh my God, it's tingling, it's cooling, it must be working. And maybe over a period of time, this can have some really nice lifting and firming effects on your skin. I don't really enjoy the feeling of stingy menthol on my skin."
