Not as good as the antirougeurs cream
I used to use the Antirougeurs cream and loved it but since they no longer make it, I had to switch. I have been using the redness expert cream for a week and it makes my face even redder. I also started to break out. The texture is good but I don’t think it works like the other cream.

Really helps with the redness
Years ago, my dermatologist recommended this line whenever I had a problem with redness. The redness occurs when I spend time outside, even with sunscreen & a hat. When I perspire it irritates my skin & poof, redness. I started using this, once I found it on Amazon, & this really helps to relieve the pain, discomfort & burning sensation. It has a cooling affect on your skin. Until I found this brand I simply suffered until the irritated skin healed. I apply this at night, especially after being outside & sweating & the redness is gone in the morning. I plan to use this until I no longer need it.

Runny
Doesn't flare up my rosacea but does not reduce redness either. Less moisturizing and runnier than Antirougeurs FORT, which appears to be discontinued. Also dislike the bulky packaging. The squeeze tube took up less space in my travel bag.

Soothing and excellent
It's very mild and very soothing to the skin. For years I had red areas on my face and it all went away with this moisturizer. Love it

Not worth it
Doesn’t really help with redness. Has an oat smell that isn’t very pleasant. Nice moisturizer that isn’t sticky. Not worth the price.
