Customer Reviews

Overall rating: 4.9 / 5 from 39 reviews.

I absolutely love this serum. Saw an immediate change in my skin after the first use, and I knew I’d be hooked. I love how it layers under my other products, and being acne prone, it has not caused any breakouts. Will definitely repurchase!

KH Prebiotic Peptide Serum

I purchased this as part of a set (serum and moisturizer) due to receiving an email for 15% off online purchase. I love the serum. It spreads so nicely on the skin after a toner. I feel like it is the right texture for my mature 71 yo skin! I am currently using it on my trip to San Francisco and other cities while on the west coast (I live on the ocean in FL) and it's drier here so this is the perfect serum. Glad I took a risk and bought it online without every trying it.

The top doesn’t close the whole way so it leaks out. Wry disappointing and so expensive to waste,

KH Prebiotic Peptide Serum

This is the only product that consistently keeps my skin hydrated year round but especially in the winter. 10/10

Kathleen S. 5/5 Verified

KH Prebiotic Peptide Serum

I love all of the Karee Hays products, but this one is my favorite. It glides on smoothly and leaves your skin looking and feeling well hydrated. I have been using it with the Koji pads for about a year now and see a significant difference in my skin. I am 63 but feel like these products have slowed the visible signs of aging. Needless to say, I wont go a day without them!

I used the prior version and loved it and am looking forward to the new one!

Elizabeth L. 5/5 Verified

KH Prebiotic Peptide Serum

I have been using the peptide serum for years. The new, rebranded packaging makes it difficult to tell how much product is left. While the new, white vessel is beautiful, I prefer the old packaging

This is my second bottle of this peptide and I am loving it. My skin has changed in the last couple years and this has saved me. My skin is more hydrated and smooth and feels so much better.

I am 74 with a long history of being in the sun. Since I have been using the peptide gel, my family has asked me what I am doing to my skin. My skin just looks better. I am very pleased.
