This works!
I’ve got Rosacea and not only does this really calm down the redness it works well with my makeup. Doesn’t pill at all. Absorbs really well, no scent or at least I do not detect it. Does not irritate my skin.

The only option for reactive skin
I have EXTREMELY sensitive skin that breaks out in either a rash or acne with anything i try to put on it. This is the only lotion i can use. My sister is the same. Anytime i switch to something cheeper, i eventually come back to this!

FAKE! Caused burning stinging and pain. AVOID
Counterfeit product-avoid! Don’t buy it from here, get the actual product from Bioderma directly. I used this and it made my face sting, itch and turn a bright red. Then came the BURNING! After avoiding it for a week my face is finally healing. I didn’t notice the horrible packaging until it was too late—compare the photo of the product I got to the actual product from Bioderma and you’ll see the difference.
It is extremely unethical for a seller to send FAKE products that cause PAIN and redness all to make a dollar. Not cool.
