Cosrx is a Korean brand that provides quality products. I use this toner after cleansing for added collagen. Works well.

Hydrating and lightweight serum that absorbs quickly and leaves skin feeling smooth and plump. Helps improve elasticity and firmness over time, while being gentle enough for sensitive skin. Great as a daily booster under moisturizer, though results take consistent use to notice.

I've been using this for well over a year and I use it after I get out of the shower in the morning, and at night when I wash my face. It allows for deeper penetration of other skin care products and I've noticed a huge difference in the texture of my skin as well. It is highly effective with no scent. I have a very mild case of rosacea (self diagnosed, lol). But this has made a significant difference in evening my skin tone and getting rid of the redness. I also apply it to my neck and chest area and have noticed a difference as well, in the way my other products work after applying it. Especially products used to lighten any dark spots like freckles etc. I've noticed a HUGE difference in that area. Because I am fair skinned, unfortunately I am prone to freckles since I was younger. So if I go out in the sun, I get sprinkled with freckles on my nose and upper cheeks as well as my chest and shoulders and although I use SPF, I do live in Florida and I've noticed since moving here from the north my skin looks so much worse. But when using this along with some other dark spot remover products it has made a huge difference in the way the products work! It's a very watery consistency but do not put it on a pad like you would for a toner this is not a toner you want it to absorb into your skin as much as possible. It is not thick at all it comes out basically like water and soaks right into your skin with a few light pads give it about a minute and you'll be ready to move on to your next step in your skincare routine. For the price I think the value for your money is excellent! I will never not have this in my skincare routine, two thumbs up and if I had more thumbs I'd give it more! Haha! And five stars, if I could give it more stars I would!

This booster serum is a powerhouse. It feels like a professional skincare treatment in a bottle. The formula is incredibly lightweight, almost watery, but it delivers intense hydration and firmness. My skin feels bouncy, smooth, and refreshed immediately after application.After consistent use, I noticed improved texture and a subtle tightening effect — especially around my cheeks and jawline. It layers perfectly with other products and never pills. The combination of peptides and niacinamide makes my skin look brighter and more even.This is one of those products that quietly upgrades your entire routine. It’s gentle, effective, and suitable for daily use. If you want that glass-skin glow, this is a must-have.
