"THE VERY BEST SERUM EVER!! I'M 83 AND PEOPLE DO NOT BELIEVE ME! THEY SAY "BUT YOUR SKIN IS LINE & WRINKLE FREE" PLUS I USE THE TOTAL REPAIR CREAM AFTERWARDS ALSO EVERYDAY! THANK YOU KATE!!!"
— Margaret R. (5/5)
"I love to try new products, but I always come back to this one. Anytime my skin is cranky, this smooths it out."
— Malinda C. (5/5)
"After my last baby, I found my skin not able to wear the products I used to. When I found Kate, it saved my face! This serum is the perfect moisturizer and brought back my skin’s glow. I have combo skin and wear it with a water moisturizer. I found when I wore it with the matching Kateceutical lotion my face would break out. I even wear it in the hot NC summers and do not have issues with breakouts. I don’t hesitate recommending this to anyone looking to improve their skincare."
— Missy N. (4/5)
"It is not very hydrating, but I can feel skin is tighter after using this serum. Overall, I think it is an effective product, although I prefer the total repair cream more."
— Tracy (4/5)
"although all products are safe this one gets a HIGH TOXICITY rating Meaning Cancer causing ingredients"
— Ray C. (1/5)
"This really makes your skin appear firmer and smoother. Have purchased multiple times."
— Anne (5/5)
"This is a must have in my skin care regimen. It is wonderful under makeup and I can wear it by itself as well. I’ve sampled lots of different serums and always come back to this one. It is gentle enough to put around my eyes when I forget the eye cream."
— Archermom (5/5)
