Amazing products
I use all CosRx products. They’re great on my maturing skin. I only use this once or twice a week at night. The rest of the time I use the AHA/BHA toner exfoliater spray.

Works well for sensitive acne prone skin!
Works pretty well so far, however definitely be mindful of using it if you have really sensitive skin as it can irritate the areas you apply it. Love the application of it too!Also, if you want the best bang for your buck, before dumping in the serum on the cotton rounds, cut the cotton rounds in half for more treatments!

Expires In 4 months…
Check expiration dates. Bought this early December 2025. My first box expires in April 2026. Which about 4 months from now. I feel like this doesn’t give me much time to use it. I never tried it before.So I did an exchange and mentioned the expiration date in hopes of getting one that will expire the end of 2026 or 2027. I’ve recently spent hundreds of dollars on this brands other products just recently to try them out and haven’t had this same issue.Not sure that I’ll keep either boxes. Just annoyed that my replacement has the same expiration date as the first one.

This is way better than any creams! Works fast and your skin still looks healthy!
I have always used benzoyl peroxide treatment cream for the little acne I get. I read all of the reviews for this product and decided to try. My skin cleared up so fast and didn’t dry out and get splotchy. I’m 67 and still get occasional breakouts. This product cleared my face almost overnight! I loved it so much I purchased 2 more during Prime Days! I will definitely keep this in my cabinet always!

Amazing Product
My son had very good skin until he turned 20. I noticed his acne problem started when he grew his hair a little & started using new hair products. He’s my only child & as his mom I wanted to find the right products for him. I looked for many products & after a few trial & error, I found this. It’s been working really well on managing his breakouts. It stings & be careful with what active ingredients of other products like facial soap you use on your skin with this. But this is an amazing product!

Great product!
So far I am really enjoying this skin care product. The effectiveness of treating blemishes is very good especially for the price. I don’t feel like it is drying my skin out, if anything evening my skins texture. I will say there is a little bit of stickiness afterwards but I just rub it in. Overall 4/5!

The product is great, but i feel like the cotton pads could have been more! I think the method to have the pads soaked is great and clean and efficient, but also rather wasteful
