How to use
General guidance from this product's category and active ingredients — always follow the directions on the package.
Trust & honesty
The concentrations these actives are typically effective at in research — not a measurement of this product.
Most research uses 2–5%; some formulas go to 10%. Very high levels can cause flushing in sensitive skin.
Niacinamide
INCI lists don't disclose amounts, and we don't claim to know this product's levels — these are the ranges these ingredients are usually effective at, so you can tell a real formula from "fairy-dusting" a marketed active. How we estimate this.

I wanted to reduce my usage of sheet masks and thought this would be a great hydrating substitute for my combination (oily-leaning) skin. However, on my first try, I left it on for 15 minutes and it gave me closed comedones. Instantly I knew this was a wrong fit for my skin type. My skin felt hydrated, but my skincare products didn't sink in well and I could feel it just forming a layer, taking some time to absorb when it usually would've seeped into my pores already. It is probably due to it...
Personally, it wasn't thick enough to be an overnight mask or even a general mask. Works best as a daytime moisturiser for people with oily skin. As someone with dry, dehydrated skin I felt that it was too light. It definitely hydrated but I would not say it is that effective at moisturising, My skin does not feel as moisturised as other moisturisers i've tried does when I wake up in the morning and my skin did not stay moisturised throughout the day when used as a day moisturiser. It absorbs...
actually in me this product so far is good, if you use in your night routine so in the morning your skin look so glowing. so far i used 3 bottle of this product. i love cosrx so much. i don't know but a lot of my skincare product was cosrx. i use this product with cosrx low ph good morning gel cleanser as cleanser, cleansing pad (red) and centela toner, after that i used this product, if the day i used sunscreen from cosrx too. i love cosrx so much, and in the other hand this product is easy ...
https://www.cosrx.com/cosrx-ultimate-nourishing-rice-spa-overnight-mask-1.html[](http://) I swear by this product! it is very gentle on my sensitive skin and can definitely leave it overnight. its consistency is just right, not too thin or thick. I used to prefer the old packaging as I can use till the last drop.
works great for me.i can use it under makeup. i have an oily t zone and it works great. no greasy feeling. my cheeks are very dry. so i use double layer in those area. in winter it doesn't give me enough hydration if i use it alone. i need to incorporate it with glycerin.
