I got this snail power essence because I wanted to try COSRX products and this was one of the most raved products from COSRX. Plus, it has 96% snail filtrate and I love snail products. I use this essence twice a day and it feels really good on the skin and makes my face feel really smooth right after using it. It's also sticky, but lightweight. However, it is in no sense a replacement for a moisturizer. However, I've used up half of the bottle already and I'm still not exactly sure what to think because I feel like it doesn't really do anything to my face. Maybe I expected it to heal my dark spots and acne scars because it contains such a high amount of snail filtrate, but I find my other products do a much better job. I just am not noticing any differences in my skin when I use it, except that it helps keep in the moisture. I don't know, I guess I'll have to think about it again after I finish the rest of the bottle.
