Incredible Serum for Hyperpigmentation
I cannot believe how much I love this Serum. It worked absolute wonders on my face in just one week, and it continues to work it's magic. If you have any sort of hyperpigmentation, acne scarring, sunspots, or dark spots from waxing, you need to add the CosRx Alpha-Arbutin 2 Discoloration Care Serum ...

Caused new breakouts
I wanted to love this, I really did! I have done research on tranexamic acid and was stoked to find this serum at Ulta for 25 dollars. I have post acne scars and I saw this was highly rated and the price wasn't bad. I used it twice a day as directed and I started noticing new breakouts. I hoped it w...

Didn't work
I have years of sun damange/hyperpigmention, bought this March 2025 during 50% off event. Been using it twice a day along with retinol and vitamin C. Can comfirm this did not work for me. I do like the texture and how easy it is to absorb.
First Thing I've Tried That Works
I have pale skin prone to redness and age spots. I've tried many different serums with no luck. This actually worked on me. Within one week I have my normal skin coloring and no irritation.
Works
I've tried many different serums for dark Spots and redness on my face. This is the first one that worked-really worked! I have a new "must have" beauty product.
Disappointed
Tried it as COSRX is a great Korean brand and was hoping it would be different than all the others. Plus, all the positive reviews. But after twice daily usage for 2 months, there was nonchange to any of my dark spots. I did before & after pics & i think it actually got worse! Thankfully i purchased this when in 50% off!
BEST FOR SKIN IN GENERAL AND ACNE
first off I wanna thank the lady that gave me the free sample of this! now I'm addicted to it and it had done wonders to my face. I don't get a lot of pimples like little small ones at the most at random spot but most of the time my face is clear and smooth bc of this product. I use it day and night and see a HUGE difference in my skin and the smoothness of my face. I even left it on a pimple over night and by morning it was small as a mustard seed ( it was a kinda huge pimple and it was inflamed). I hate not a lot of ppl know about this product bc it TRULY works!!!

- 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
- Q
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
