  • Serum-ly Impressed
Age is catching me and a recent bout with Cancer left me getting rid of almost every body and face product I had. My skin had gotten dry and the wrinkles were moving in in pairs. So I started putting together a battle plan that involved all new face products with no bad chemicals. It also included a Derma Roller and it's recommended to use a good serum after using the Derma Roller. After doing some research through multiple dermatologists' websites on what products work best or what ingredients to look for in a product, I found COSRX The 6 Peptide Skin Booster. This is so easy to use. After cleansing or using the Derma Roller, you just pat it all over your face and let it soak in. It's not like some serums that feel like they sit on top of your skin like a coating of slime, it actually seems to be absorbed. After it has had time to be absorbed, just a few minutes, I follow it with my moisturizer. So easy, no long wait and your skin still feels clean. And it's getting all those good things that fight dry, aging, wrinkly skin. What more can you ask for? I'll be keeping this in my anti-aging arsenal as long as it's available, which I hope is a long time. ... show more

  • holy grail item for skincare
This works really well to plump up the skin compared to other brands. I'm in my early 50s with dry skin. The wrinkles are lessened when I use this versus when I don't use it daily. Eleven and marionette lines are significantly diminished, forehead lines lessened. Pores are minimized, neck lines are lessened, skin stays moisturized throughout the day. A little goes a long way. It has a thin viscosity so use it after washing and toner and before heavier serums, moisturizer and sunscreen. No sensitivity issues, no acne, no interactions with other skincare items. ... show more

  • Love it!
It's like water to me; no stickiness, no stinging and the bottle last a long time. But my wife can't use it. It burns her sensitive skin. So I put her on COSRX essence serum and the cosrx snail mucin. Both bottles sizes and the jar size will last for a good while. It gives you that glowing appearance. Thx. ... show more

  • This is my second purchase
I have sensitive combination skin and this does wonders and causes zero irritation. I use daily and never has a minutes trouble. I’ll always have this in stock as a staple in my skincare routine.

  • Pretty good so far
Been using this product for couple of days now, I have not seen any breakouts. This is not a thick serum, but is a little bit oily. It does leave your screen shiny after applying it. It is very moisturizing, I didn't have to put on a moisturizer after. The product has no scent, and it last very long. I put that on at night about 11:30, and still feel it at 7am, but also feel oily on and around my nose, so maybe my skin is still trying to get use to it. ... show more

  • Love this serum and have repurchased many times! Great ingredients, great value!
I LOVE this serum!!!! I’m a skincare fanatic, and this one has so many great ingredients. I’ve noticed a difference in my skin with texture, less hyperpigmentation, and overall tone. It goes very well with other serums, or this would be a great one if just choosing one to keep routine streamlined. I’ve repurchased numerous times and will continue to do so! ... show more

  • A great product!
One of my favorite products. I've been using this nightly for about 2 years. It really has helped with my skin hydration. Goes on easily, absorbs super well, isn't greasy, and has never irritated my skin. Recommend!
