Okay
This serum is okay but it is not great under makeup as it is a bit too thick?

Exceeded my expectations - a must try product!
Here’s the revised version: I had low expectations when I bought this serum, but after 3 weeks of use, I’m blown away! I have combination, sensitive skin with redness and hormonal acne around my chin. Using it once daily, I was thrilled it didn’t irritate my skin. It calms redness, soothes breakouts, and hydrates thanks to niacinamide and snail mucin. I even stopped using my COSRX snail mucin, saving time and money. The packaging is simple yet effective, with a tightly sealed dropper and narrow mouthpiece to maintain the product’s potency. Box and bottle also has printed ingredients and directions on how to use which is super helpful. This serum is a hidden gem—underrated but incredibly effective. Highly recommend and will definitely repurchase!

Very good
Very good product, I did patch test before and then stated to use is tho I switched to higher percentage of the Azelaic acid to 20%
