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!

PLEASE REVIEW — FORMULA CHANGED!!!
I wish I would’ve posted a review PRIOR to the formula changing but just know that I LOVED this serum. I’ve struggled with hormonal acne (PCOS) and eczema for as long as I can remember. Finally, last summer my dermatologist put me on (3) different RX including Spironolactone and Accutane. I was so tired so I stopped everything except for CeraVe cleanser, retinol (Tretinoin) and CeraVe healing ointment. My made up skin routine was working until I used too much Tretinoin and burned my face. I had read great reviews about this product so I thought, I might as well try it — and IT WORKED! I’ve been using this product for almost a year and I loved it. However, 3 weeks ago when I ordered it, I noticed the bottle had a green tint. I could tell after one use that the feel of the serum was different, more watery, not as thick as it used to be. The smell was also different. Still, I kept using it for nearly 2 weeks and I experienced 2 breakouts! Sure enough, I stopped the product and within a few days, my skin was back to normal. I am very upset because as someone who has extremely sensitive skin, this worked but unfortunately, the new formula isn’t for me.
