COSRX AHA BHA Vitamin C Booster Serum 1.01fl.oz/30ml, Anti Aging, Plumping, Hydrating Serum with Niacinamide, Not Tested on Animals, No Parabens, Korean Skincare

I honestly noticed a difference after using this. My face started to look brighter. Is going to be a regular item in my skincare.

Love it! Use regularly and your skin will take on a glow. Combine with moisturizer and facial cleanser from same company.

Love this serum; my skin is glowing and it gives all day moisture

Makes my face feel nice and clean after using.

This is an easy add in to any skincare routine and, just like all the other COSRX products I've tried, it's effective and easy to use.

It did not work for me that well, but I also don’t think it was for my skin type.

Estos productos nunca me van a decepcionar así que muy bueno y sobre todo económico

This serum is a delight. Goes on watery, sits well under subsequent layering, works well with matching toner, doesnt cause irritation and doesnt have a ton of extra ingredients or fragrance. Great stuff! Keeps me exfoliated and fresh!

This one is awesome, especially for acne prone skin. Already used 1 bottle and have ordered the second one. Thanks

it does the magic
