Works as created.
Have been using for a few weeks and have noticed 15% improvement in skin and issues. I did notice a difference in the first 24 hours as advertised. It is suggested need a full month I think to see the true results. At 50 I have pre menopausal skin issues- the redness & inflammation, acne, tightness and sensitivity. It is helping in addition to the other Avene skin products that come in the trial box for sensitive or SOS skin box trial size I think ot is called. This has made a difference. It is easy to apply. I use morning and night. It is different from the Cicalfate + Cream. I use that also as needed. I am happy and recommend it. The price is higher than what I spend. But I wanted to try it to see of i need more than just what was in the Avene sensitive skin trial size box they have. My skin is really red and irritated so the $40 for the bottle is was willing to try because it's painful on my face.

Okay serum, not as good as the cream though
I am obsessed with the cream version of this so I thought I’d give this a try. The dropper top allows for easy application. The formula is light and non greasy and absorbs easily. No harsh fragrances. I would use it when I had eczema flares on my face and feel like it didn’t work near as well in helping with skin irritation as the cream does. As of now I don’t use it as part of my regular skin care. Do I think it’s a bad product? No, but it didn’t really work wonders for me. Not sure I would purchase again.

Helps with redness and softens skin
I have sensitive, mild rosacea skin. Had a facial recently and the aesthetician suggested I get a serum to help with moisturizer as I am almost 40. I’ve tried a lot of serums and either they are sticky and not really hydrating or break my skin out in a rash. This serum is amazing. Helps calm the redness in my cheeks and my skin is moisturized and soft all day. It feels a little sticky at first but it goes away. I apply in this order OSEA sea mineral mist toner to prep the skin, this serum and top off with Chanel La Solution 10 for sensitive skin.

Sensitive skin
Such a good product. I use after micro needling when skin is sensitive. Also a great product to use as a barrier serum when starting tretinoin cream.

Saved my skin during an eczema flare up
This saved my skin! I had an eczema flare on my face, and my usual products weren’t working. A friend recommended the Avene brand and within 3 days of using this rescue barrier serum, my flare was almost completely gone! This saved my face!
