Calming and lightweight
I really like how lightweight and soothing this serum feels on my skin. It absorbs quickly without feeling sticky or heavy, and it layers nicely with the rest of my skincare. My skin feels calmer and more comfortable after using it, and I like that it gives hydration without making me feel greasy.

I don’t necessarily struggle with redness but my skin barrier gets compromised sometimes because of tretinoin or over exfoliation and this has been crucial in helping my skin bounce back. The texture is really good too

Peels Off Instead of Absorbing
I was very disappointed with this serum. It didn’t absorb into my skin at all. Instead, it dried into a film and started peeling off in tiny pieces. Every time I applied sunscreen or another product on top, the serum rolled up and came off. I’ve never experienced this with any other serum.

Skin saver
I have suffered with acne for my entire adult life. I’ve used this product consistently for a month and I am amazed by the results. I have tried all kinds of redness targeted products but none have done what this product does. 1000000% recommended

Full disclosure, I’m using this concurrently with a series of IPL laser treatments and daily red light therapy. I think it is making a difference in redness and texture with my other interventions. I don’t think it will take care of everything on its own but I’m a fan of

I love this product. I’m a teenager and struggle with redness and allergies. I have seen a big improvement in redness.

Good but not THAT good
I can see this helping my redness and helping my skin but I can only use it as light as it peels SO bad under makeup, even if I have a bare face and happen to rub my hand on my face it comes off in clumps! I’ve been using 2-3 pumps of this and one pump of mosturizer. Again it’s a good product but impossible to use under makeup

Not worth the price
Ok, I didn’t notice an improvement but it didn’t make my rosacea worse. Not sure it’s worth the price.
