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.

My skin loves this.
This might be the best face wash I’ve ever used, and I do NOT say that lightly. I have it on subscription because I panic a little at the thought of running out.
For context: my skin has gone from oily, acne-prone chaos to “surprise! now you’re dry and post-menopausal” and somehow this cleanser handles ALL of it beautifully.
It cleans deeply without stripping my skin, leaves my face feeling soft instead of tight, and somehow manages to make my skin look calmer, smoother, and less angry overall. My pores even look better.
Also… the texture? Weirdly satisfying!! It has this rich, creamy feel that feels luxurious without being heavy.
Now for my one complaint:
The cap sucks and we are in an ongoing toxic relationship.
The cleanser itself is elegant Korean skincare perfection. 5 stars!
