The Alpha-Arbutin 2 Discoloration Care Serum

I have already shifted my skincare routine to COSRX.. bought total range now. I can say this is the best thing I did for my skin so far. Excellent product very effective from the first use itself. It has improved my skin in so many levels. Highly recommend it.

It made my skin texture to improve, and clear my spots on my face, good value for money

Works with consistency. It has contributed to fading dark marks along with other products (vitamin C, mandelic, retinoids). No irritation.

Very effective and amazing serum OMG. It’s really helped to even out my skin tone and reduce hyperpigmentation. I’ve seen a great improvement like old hyperpigmentation marks has started to fade. I’ll be back to purchase more. Also no skin irradiation I use it AM and PM everyday THANK YOU COSRX

Considering the generous amount (1.7oz) and price, this is one of the best hyperpigmentation products that is available otc. Another one is Regimen Lab's Level serum which is yes, a bit better. But since these type of products take a long time to work, this one will last you way longer than the regimen lab one which only comes in 1oz and is more expensive. Over 6 months or so, they would probably plateau and reach the same level of results give or take. The only thing I do not like about this product is that it has dimethicone which while this serum is light still gives the skin the slightest amount of slip which I hate. I wish they would reformulate this and keep all the amazing brightening ingredients and save the dimethicone for their moisturizer line where it belongs.
