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.

Spot lightening
This is real nice stuff. Notice a difference upon using. I wouldn’t say it’s so much hydrating or moisturizing….not the reason I picked it. You can see the brightening effect right away.

For me, Cosrx really can do no wrong 😃
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.

Good product
Love this product. I got some of this as a freebie from Ulta. I love what it does for my skin. Id definitely improved the look of dark spots and the texture has improved

Slight improvement
I’ve been using this twice daily for a while now. I’ve noticed a slight lightening of my skin overall, however my age spots have not lightened, which is what I am after.

This Works
I am 58, i love the dropper. I can use it without touching my skin. I love that part because no germs get on the tip of the dropper. As long as I don’t touch my face with it which I don’t. I love the consistency, and you do not need more than I would say. I have to a full dropper full per use. My skin feels absolutely hydrated. After you using I use it at night. I also use a little bit on my forehead. Before I do my makeup, and because my forehead eh gets a bit drier. I can tell that the subtle lines around my eyes are not as noticeable. And I can tell that my skin looks better after I’ve used a little bit and then use my makeup. And most products do not go on my face very well before I use makeup. For some reason, they just do not React well with makeup. I have even tried waiting an hour before I put on my makeup. And that does not help. It seems to sit on top of my skin. Any skin care products? I have used before this one.This does not do that, and that is most important to me. I had actually discovered that on accident, because I put a little bit on my face by accident before I did my makeup. And when I did my makeup, it was really great. However, I realized I put it on After I had put on my makeup, so I had forgotten and then remembered, and I thought, wow, this did not. Make my makeup look blotchy or streaky. So the next time I tried it again, and it worked fine. I only needed it on my forehead, but when I put my makeup on, it did not react badly at all with my makeup.That was shocking. So I one hundred percent love this product.

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 chance—but this time, I introduced it gradually. It worked, and I’m happy with the results! Here’s 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 hours—like a patch test. It did itch a little, but nothing compared to my first experience.Day 3: Since I didn’t 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 “sandwich method”—a 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 daily—only in the morning (I haven’t tried applying it at night yet).Now, my dark spots are less noticeable, and my pores look more refined. I’m so glad I gave this product a second chance!

Real Effective
This lightened a dark spot by at least 75% on my cheek, can’t say it will do the same for anyone else. I was pleased. Noticed difference in 7 days, the effectiveness was great. I don’t recall a scent, or oiliness it is real light and goes into skin fast.

حسيت يعطي حياة للبشره ، خصوصا اذا بشرتك من النوع الباهت ، مره كويس

Contrairement à d’autres produits, il agit bien plus rapidement. Visage plus lumineux étonnamment, moins sombre sur des tâches de pigmentation en quelques utilisations.

La confezione è robusta. Il siero ha 50 ml. È di piu degli altri serum, che hanno di solito 30 ml. Il profumo è piacevole, non forte. Il risultato non si vede subito. Leggendo le recensioni, lo vedrete fra 3-4 settimane.

Amazing product. Really like this serum and works well on sensitive, dry and combination skin types (mine varies between the three due to fluctuating UK weather). Doesn’t have any smell and does not sting at all! I find it a little expensive but a great one to put your hands on! And it does show very visible effects.
