- Q
This product seems to make a coating over your face. I don't know if my moisturizer an SPF even get absorbed through it. It's very noticeable when you go to wash your face and there's definitely a slippery coating over your face that takes several water rinsing to get it off.
- Asked by Curly
- Official Answer By COSRX - Brand EngageWe appreciate your feedback and understand your concerns regarding the texture and absorption of the product. The serum is designed to provide hydration and enhance your skincare routine, but it may feel slightly slippery depending on individual skin types. To ensure optimal absorption of your moisturizer and SPF, we recommend applying these products after the serum has fully absorbed into your skin. If you find that the serum is leaving a coating that feels uncomfortable, you might want to adjust the amount you are using or allow more time for it to absorb before applying other products.Was this answer helpful to you

Since incorporating this serum into my skincare routine, I noticed a significant purging phase after about a week of use.

Great for acne prone skin
For context I have combination acne-prone skin with mild anti aging concerns and I'm also a licensed esthi. This serum is something I found kinda boring at first but as I've used it (for about 6 months now) I've realized it's my favorite serum. When I first got it I had a couple other serums to compare it to (some thicker hyaluronic ones) and this one is not as moisturizing as the others BUT its watery texture makes it fantastic for layering. The other serums would sometimes over-occlude my skin but this one my skin "drinks up". I can use this twice a day with no issues, and it's especially refreshing in the summertime and very humid weather. It addresses both anti-aging concerns and oil/inflammation concerns, which are hard to balance at the same time. It's the perfect sweet spot for me and it helps me customize my hydration level depending on where my skin is at. Strongly recommend!
Great Purchase!
Only been using this product for 1 wk....goes on easily and softens fine lines.
Breaks me out
Everytime I try this it breaks me out in acne. And i never have acne problems.
Not sure what to think
I can't say 100%, but I broke out horribly after I used this for a few days. I can't say it was definitely this product, but I stopped using it and my face got much better. So sadly I didn't see a difference and I may try again.
Perfect serum, imperfect nozzle
This is a great all-in-one serum. It has all the ingredients I was looking for. After only 1 week, I noticed my skin becoming smoother and more hydrated. I use this before my morning skincare routine which includes vitamin C I also use it before I use retinol at night. I let it dry for at least 2 minutes before applying the next product. I took off one star because the nozzle is so short it's hard to get the serum onto your fingertips. Inevitably, some of it drips down the bottle
