Reviews

Caused new breakouts

"I've done research on Tranexamic Acid and I was happy to find this serum at Ulta for 25 dollars. I wanted to love this. I even tried it multiple times hoping my skin was reacting to something else and not this. Unfortunately this product caused new acne and tiny red bumps all over my cheeks where I applied it. It seems like there may be some sort of oil in this product. I advise anyone with skin sensitivities to be cautious with this product. Definitely do a patch test first and try that for a few days first."

The serum goes on smoothly.

"The serum goes on smoothly. I have only been using it for about 10 days so I can’t say yet if it has improved any dark spots yet, but my skin looks healthy and well moisturized without any acne breakouts. So far so good!"

— Alyssa E. (5/5)

I’ve been using The Alpha-Arbutin

"I’ve been using The Alpha-Arbutin 2 Discoloration Care Serum consistently, and it’s a solid option for targeting uneven skin tone. The texture is lightweight and absorbs quickly without leaving any sticky residue, which makes it easy to layer with other products. Over time, I noticed a visible improvement in post-acne marks and overall brightness. My skin looks more even and less dull. The combination of tranexamic acid and niacinamide works well to calm and gradually fade discoloration without irritating my skin. That said, results are not instant—you need consistency and daily sunscreen to actually see progress. It’s not aggressive, but that’s also why it’s gentle and suitable for regular use. Overall, a reliable serum if your goal is to improve dark spots and maintain a more even complexion."

— Ivette D. (5/5)

The COSRX Alpha-Arbutin 2 Discoloration

"The COSRX Alpha-Arbutin 2 Discoloration Care Serum has been a standout in my routine for targeting uneven tone. The formula is lightweight and absorbs quickly, making it easy to layer with other actives without feeling heavy or sticky. It has that elegant, simple COSRX texture that feels effective but gentle on the skin. After a couple of weeks of consistent use, I’ve noticed my complexion looking more even and overall brighter. Areas of discoloration are starting to look softer and less noticeable, and my skin has a clearer, more refined appearance. If you’re looking for a gentle but effective product to help with discoloration and tone, this serum is a great addition to a results-focused skincare routine."

— Dipali S. (5/5)
