Can this product be used along with retinol?
- Asked by Anat
- Official Answer By COSRX - Brand EngageYes, you can use this serum in conjunction with retinol. The peptide serum helps enhance the affects of subsequent serums and ampoules when used before them. However, we always recommend doing a patch test first and introducing new products gradually into your routine. If you have sensitive skin or are concerned about potential irritation, it might be best to use them on alternate days.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...

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
Must Have
It's the start of morning and night routine. When I bought my first bottle, it was unclear to me the importance and if it was truly working. After completely using two bottles, I can tell the difference in my texture and glow if I skip this step.
My Favorite Serum
The fact that this serum is under $30 and outperforms serums that are $100+ will never cease to amaze me. Not to mention the amount of product you receive is unreal. This serum does it all and then some. My skin looks and feels so much better within minutes after application. I will never stop repurchasing this product. It's truly incredible.
