This is a dependable product to always have on hand. It’s one of the few products I use that give a noticeable change in skin tone and blemish after use. This was the first product I used to turn me onto this brand and because of it I started buying other products from them. I only wear this at night and I make sure to wear sunscreen during the day.

So I am huge fan of snail products. My face looks the best it has looked in years. I have dark spots as I have gotten older. This serum has been great is reducing those.

I wish I could love this product as I think Cosrx is a great brand, but I do feel like it made me breakout. Before I was using the VERSED Blemish serum, and I think that just works better for me.I’m someone with combination skin, I get a lot of cystic chin acne when I’m not careful about products/my diet. This definitely made me breakout as I started getting acne in places I don’t usually, and very quickly after I started using was when I noticed. Soon as I stopped using it my breakouts started clearing up.The product itself feels nice, but it’s not as satisfying feeling as the VERSED serum i was using.

I use this serum daily and my break outs have diminished significantly - I’m actually shocked at how effective it is. The best part about this serum is it doesn’t dry out my skin. Most serums I use to treat my acne, I need to use sparingly or it will irritate my skin and cause further breakouts. I can use this daily and it after a couple weeks of regular usage I’ve cut out other serums and just use this. My skin is softer, more even, and blemish free. Plus the product last so long! A little drop goes along way.
