Brightening & gentle exfoliation in one

great all-in-one serum that helps fade acne scars, even skin tone, and improve texture. AHA & BHA keep pores clear, while vitamin C brightens the skin. Not too harsh, so even sensitive skin can use it. Works best when followed by sunscreen during the day :)

This vitamin C serum is lightweight and absorbs quickly into the skin. After using it regularly, my skin looks brighter, smoother, and more radiant.

Skin renewed

I’ve only been using the COSRX AHA BHA Vitamin C booster for a short time, but I’m already seeing results . My skin looks clearer, and more refreshed. The scent isn’t bad or good, just neutral, which I don’t mind. For the price, it’s definitely worth it. A solid pick if you're looking to gently brighten and exfoliate your skin.

Brightens, Smooths & Clears – My Skin Loves It!

I’ve been using this COSRX booster serum for a couple of weeks and I already see a noticeable difference. My skin looks brighter, smoother, and more even-toned. The combination of AHA, BHA, and Vitamin C works wonderfully together — gently exfoliating while also giving a healthy glow. It absorbs quickly, has no overpowering scent, and layers well with my other skincare products. I haven’t experienced any irritation, even with sensitive skin, which is a big win. If you’re looking to fade dark spots, reduce dullness, or smooth texture, this serum is a fantastic choice!

Helps Brighten

Good quality vitamin C booster serum. It is gentle and I use it frequently/daily. Nice size bottle and the benefit of using this serum for me, being of older age, is my skin looks brighter. No skin sensitivity and the composition of the serum is light, and has a watery feel but it works.
