The serum made my skin feel moisturized and it has no fragrance. I think it may have slightly lightened it but I need to use it for longer to be sure. I had no negative side effects.
Easy to Use
Reviewed at

My experience with the product has been good so far. The serum bottle is easy to open and the applicator is great. The serum itself absorbs quickly into the skin and it doesn't have a smell. In the week that I have been testing it out, I did notice some purging but it didn't last long. I've noticed that in the week that I've been using it, my skin is brighter, spots are lighter, and the appearance of my scars are changing.
Great product!

Great product! It definitely works, I had a couple acne scars and the one bad one has faded immensely since using this product. My skin has a nice glow to it as well.
A staple
Reviewed at

My skin looks brighter and more even overall. I kind of have sensitive skin, and many other brightening products have caused irritation or dryness, but this one didn't. It absorbs quickly and doesn't leave any sticky or greasy feeling, which is a big plus
Brighter skin!

I was very pleased with the product. There is a noticeable difference with how brighter my skin is overall. It's not sticky, leaves no residue and has a neutral smell

- Q
Can I use this with the blemish pore pads?
- Asked by Faith
- Official Answer By COSRX - Brand EngageYes, you can use the Alpha-Arbutin 2% Discoloration Care Serum along with the One Step Original Blemish Pore Clear Pads. We recommend using the blemish pore pads first to help exfoliate and clear your pores. After that, you can apply the Alpha-Arbutin serum to target discoloration and improve your skin tone. Just be sure to follow up with a moisturizer and sunscreen during the day for the best results. If you have sensitive skin, we suggest doing a patch test before using both products together to ensure compatibility.Was this answer helpful to you

Should i use this before or after my CORSX 6 peptide skin booster?
- Asked by T
- Official Answer By COSRX - Brand EngageFor optimal results, we recommend applying the Alpha-Arbutin Serum after the 6 Peptide Skin Booster. Since the peptide serum is designed as the first-step booster to enhance the affects of subsequent serums and ampoules, it should be applied first, followed by the Alpha-Arbutin Serum.Was this answer helpful to you
