Very Hydrating
04/06/26
I have volume loss around my eyes and deep set wrinkles. My skincare routine to combat my eye problems is to use Matrixyl 10% + HA and Argireline Solution 10% from the Ordinary. I tried the Blue Peptide Serum as a replacement and have been pleased with the results. The Blue peptide keeps my eyes just as hydrated. I haven't had it that long to decide whether I will swap from the Ordinary to the Blue peptide but thinking about it.

House of Blue is my new go-to!
04/06/26
This blue serum is packed with such moisturizing and skin-plumping ingredients! My skin feels so radiant and hydrated, and still able to breathe! This serum makes my face feel so plump and taut- I feel like my skin is going to experience reverse-aging. Excited to see the continued results once I’m done with the bottle!! I have been getting so many compliments on my skin since I began using it 1. 5 weeks ago. And it felt serendipitous that the compliments came at a museum where I was standing near a huge blue art piece, and at a restaurant that was name Blue sushi

Hydration, Glow, and No Breakouts
04/06/26
I've only been using this serum for about three weeks now, but so far I'm really impressed. I have sensitive, acne-prone, and milia-prone skin, and it hasn't triggered any irritation, breakouts, or milia. This serum leaves my skin looking plump, hydrated, and radiant. The texture is on the thicker side, but it spreads effortlessly and absorbs beautifully without feeling heavy or sticky. My skin has always loved COSRX products, and this new Blue Peptide serum is no exception. It's beautifully formulated, feels luxurious on the skin, and the vibrant blue color makes it stunning to look at. While it's still early, this serum has quickly become a favorite in my routine.

Blue Peptide for the win
02/06/26
I’ve been using COSRX The Blue Peptide Serum daily on my face and neck for the past month, and the biggest improvement I’ve noticed is in my neck. The skin on my neck looks firmer, smoother, and more toned, with less visible sagging than before. I’ve also seen some improvement in the firmness of my face, especially around my jawline. The serum has a lightweight, comfortable texture that absorbs quickly and feels great on my skin. I have sensitive skin and experienced no irritation, redness, or breakouts during use. My before-and-after photos show the noticeable difference, especially in the appearance of my neck. Overall, I’m very happy with the results and will continue using it.

New Skincare Staple!
29/05/26
As someone with acne prone skin, this is the perfect serum to improve skin texture and appearance! I really love how light weight the serum is and how glowy it immediately made my skin! After only a week of use, I have noticed a smoother complexion as well as fading of old acne scarring/marks!
