- Q
Can I apply this onto a cotton pad and sweep over my face?
- Asked by AJ
- Official Answer By COSRX - Brand EngageYes, you can apply the serum onto a cotton pad and gently sweep it over your face. However, for optimal absorption, we recommend applying the serum directly to your skin with your fingertips. This method allows for better penetration of the active ingredients. If you prefer using a cotton pad, just be sure to use a gentle sweeping motion to avoid any irritation.Was this answer helpful to you

- Q
Hi! Could I use this with azeliac acid 10% from good molecules or is it not a recommended combination? Thank you.
- Asked by LearningSkincare305
- Official Answer By COSRX - Brand EngageWe are unable to provide accurate guidance on using with products from other brands. However, it's always best to introduce new products gradually and monitor your skin for any signs of irritation. As always, if you have sensitive skin or specific concerns, it's a good idea to do a patch test first or consult with a dermatologist.Was this answer helpful to you
- 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. After Influenster posted about it on Instagram, I discovered that many others experienced similar purging effects. I have dry/combination skin, and to manage the purging, I switc...

Wow!
Wow! This product is amazing. I have sensitive skin and had zero reaction to this product. In fact, this feels so very soothing on the skin. It is a wonderful texture, perhaps like a slippery thick water. It is not at all sticky ans absorbs well. I used it twice a day and it worked well under moisturizers and makeup. Using this i noticed fine lines decreased, texture very noticeably smoothed out, skin stayed plump and firm. Oil and dryness seems balanced. Will repurchase this one!
Love
Can tell a huge difference in my skin using this serum! Helps with lines and firmness.
Combo skin girly- A GAME CHANGER! < 3
After using only a few times, I noticed my skin was looking and feeling so smooth- like i have a smoothening filter irl. and realized it was cause of this!! that's coming from someone who has kept it very simple. I do my Cerave facewash, THIS, snail mucin, and moisturize with Torriden which also has hylauronic acid (look into how it pairs great w snail mucin) and Y'ALLL it literally gives me that glass skin look. So shocked. I want to assume the bad reviews are due to using other products that have harsh ingredients that may clash with this or something? redgardless everyone's skin is different. it's a lightweight, watery product. WORTH A TRY especially pairing it with snail mucin after!
I love this product.
I will purchase this product again.
I use Dior, Lancome, Shiseido
I wondered if this product actually worked on my skin, because I usually wear Dior, Shiseido, Lancome Absolue serums and creams. Then I travelled for 2 months with everything but this one specifically. Not even a week later, I lost my "glass skin" youthful look. Now I am absolutely in love with KBeauty!!! I will just finish the ones I have today (after using years) and stop wasting $ on things that are expensive but "okay". This is my favorite skin care step now.
