Works quickly to calm itch
Size: 6.76 Ounce (Pack of 1)
I had an itchy outbreak on the back of my hand the day this product arrived. Perfect timing. Applied Avene and within a short time the itch calmed almost 100%. Slept through the night and this morning, the red rash is about 95% healed. So glad I bought this. Just another old age issue to deal with.

Excellent for my sensitive skin and rosacea
Another excellent product from this brand. I have type 1 rosacea on my cheeks, even when I avoid triggers (like red wine, warm weather, etc.), and very sensitive skin overall. I've been using the cicalfate serum from this brand for the sensitivity, but it didn't help the redness. After two weeks of using this twice daily, I noticed a significant difference. After a month, I had no redness unless I encountered a trigger. Even then, the intensity of the redness seemed less. I tried going without this product for a month when the first bottle ran out, and sadly, the redness started coming back within a cycle of weeks. I've got this on auto-delivery now, along with the cicalfate serum. I never want to be without it!

Best moisturizer for sensitive skin
I have very sensitive skin and have tried many products over the years. This is by far the best daily moisturizer. I don’t wear makeup other than under eye concealer. This keeps my skin looking and feeling great. Not greasy. One bottle lasts about a month. I have probably bought this 10 times in the past year.

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.
