A high-concentration serum containing 2% Alpha-Arbutin and three key ingredients, effectively addressing post-inflammatory hyperpigmentation (PIH) and various pigmentation concerns. This powerful formula helps fade discoloration, even out skin tone, and improve skin clarity for a more radiant and even complexion.
Formulated with Ferulic Acid and Glutathione for enhanced synergy, it accelerates scar healing. This fast-absorbing serum provides soothing hydration for sensitive skin, leaving a non-sticky, refreshing finish without irritation. Perfect for all skin types, especially acne-prone skin.
Key Ingredients: Alpha-arbutin helps reduce pigmentation in age spots, acne scars, and post-acne redness. Tranexamic Acid treats discoloration. Niacinamide smooths skin texture and addresses fine lines.
How to Use: 1. After cleansing, dispense an appropriate amount of serum and apply evenly to your face. 2. For targeted care, layer 2-3 times as needed.
Patch Test Recommended: Perform a patch test on the body before using on the face. Proceed to using on the face if no irritation occurs in 24 hours. Consult with your doctor immediately if irritation occurs.

For me, Cosrx really can do no wrong ð
Another Coxrx skincare product I love. This COSRX 2% Alpha Arbutin Discoloration Care Face Serum with Niacinamide, Glutathione, and Tranexamic Acid is lightweight, a light amber color, and easy to apply to my skin without tugging or dragging of my skin.It’s not heavy at all. I had zero irritation to my rosacea-prone skin. I did do a patch test, and that is recommended if you aren’t sure if you will react to ingredients or a product you’ve not tried before, and this is my first try of this blend.In the morning, I cleanse my face, apply my toner with a pad to be sure that all the oil-based cleanser is removed, wait at least 10 minutes, and then apply vitamin c serum, wait another at least 10 minutes, and then I apply this serum–this serum replaces my usual application of niacinamide serum, since it has niacinamide plus the other actives. Then I go on with my other skincare. I don’t use this at night since I use a retinoid and do not like to use other actives with my retinoid.I also like that this is over an ounce and a half. Some of Cosrx’s bottles are less than an ounce.This is likely hydrating because of its ingredients, but it’s not going to be super emollient like some serums, but since I use snail mucin and moisturizer, I have enough hydration there.As for effectiveness, only time will tell in that regard–months, not days or weeks! It takes patience and consistency to see results and expecting to see results after a few days or a couple of weeks is unrealistic. I’m not expecting miracles but I do believe this will help my aging skin even if in a small way, with consistent use.Happy with my order.

This is a game changer!
This works great! I have been using nothing but Cosrx products, snail mucin w/niacinamide, vitamin C, and now this. Within just a couple days of adding this to my routine I’ve noticed a huge difference! My skin is brighter, more even in tone, and dark spots are certainly fading! I’ve worked outside in the sun for years and in just a couple of days I’m really blown away at the results.

Brightening Hero for Even Skin Tone
Iâve been using the COSRX The Alpha-Arbutin 2 Discoloration Care Serum for a few weeks now, and Iâm genuinely impressed with the results. The lightweight texture absorbs quickly without any sticky feeling, and itâs gentle enough for daily useâeven on my sensitive skin.The 2% Alpha-Arbutin combined with Niacinamide and Tranexamic Acid is a powerhouse blend for tackling hyperpigmentation and dark spots. Iâve noticed a visible improvement in my skin toneâitâs more even, and those stubborn acne marks are slowly fading. Plus, it hydrates well thanks to Hyaluronic Acid and doesnât irritate my skin at all.It feels like a premium formula at a very reasonable price point. The packaging is simple and functional, and one bottle lasts a decent amount of time with consistent use. If youâre struggling with discoloration or uneven skin tone, this serum is definitely worth trying!

Worth a try!
I used this serum on my face for several reddish spots (I have been using it for over a month now) and it lightened then considerably although not completely. It is quite sticky if not rubbed into the skin thoroughly. I had no irritation from this serum which is also a bonus. All in all, I would recommend you try it.

TOTALLY WORTH IT! BUT⦠If You Have Hypersensitive Skin, This Might Help!
My skin is extremely reactive to many products, even those marketed for sensitive skin. On top of that, I also have rosacea, so I was hesitant about trying this product. However, after reading some reviews and researching its three main active ingredients, I decided to give it a shot.The first application didn’t go well. A few hours after applying it, my face started itching intensely, followed by an unbearable burning sensation. That night, my skin felt so dry that I had to layer multiple applications of my usual moisturizer, plus a second one with calming properties. Despite this, the itching and burning persisted for about a week and a half.Once my skin had recovered, I decided to give the product a second chanceâbut this time, I introduced it gradually. It worked, and Iâm happy with the results! Hereâs how I did it:Before StartingCheck if any of the products in your skincare routine (or even your makeup) contain niacinamide and at what percentage. Too much niacinamide can cause irritation. In my case, I was also using:COSRX 6X Peptide Collagen Booster Toner Serum (with niacinamide and hyaluronic acid)Beauty of Joseon Ginseng Essence Water Hydrating Face Toner (contains 2% niacinamide)I had to stop using these temporarily.My Step-by-Step ApproachDay 1: I applied a small amount of the product on a single dark spot (the one I wanted to fade) and waited 24 hoursâlike a patch test. It did itch a little, but nothing compared to my first experience.Day 3: Since I didnât have a bad reaction, I repeated the same process. The itching and burning sensation had subsided, so I felt ready to try it on my entire face.Day 5: I used the âsandwich methodââa light layer of moisturizer, followed by a layer of the product, then another layer of moisturizer. After waiting 24 hours, I did feel some itching, but it was tolerable.Weeks 2 & 3: I began using the product twice a week.Weeks 4 & 5: I increased usage to every other day.Week 6: I started using it dailyâonly in the morning (I havenât tried applying it at night yet).Now, my dark spots are less noticeable, and my pores look more refined. Iâm so glad I gave this product a second chance!

Not the only thing Iâm using but itâs working!
It takes time to fade discoloration like melisma or sun damage, but I can tell a difference in just over a week. The caveat here is itâs not the only thing Iâm using â I also have a fade serum from MUAC that I started using recently too. I use that during the day with my vitamin C, and I use this as night. Cosrx never disappoints me tho â everything Iâve tried has been excellent. The texture is nice â a little slip, light, soaks in quickly and isnât greasy. Minimal smell. A good deal.
