Glow, Lift & Rejuvenate with KNU Serum
I’ve been using the KNU Serum by Michael Todd Beauty for a few weeks, and I’m loving the results! My skin feels hydrated, soft, and naturally glowing without any heaviness, and I’ve noticed my fine lines look less visible. I love that it’s lightweight, absorbs quickly, and contains aloe vera, peptides, and botanical extracts to nourish and calm the skin, plus it offers SPF protection. Perfect for my daily routine, this serum lifts, brightens, and firms, making it a must-have for anyone looking to rejuvenate their skin.

Glowy and hydrated after 2 days!
This serum is ever better than I expected. Even after just a couple of days using it my skin looks brighter and feels sooo much more hydrated. The ingredients are clean which I love and it smells clean too! This is perfect if you’re looking for my hydration without a heavy cream feeling on your skin

Tightens my skin after every use!
I’ve been using this for a little while now and really like how it makes my skin feel. My face feels noticeably tighter and more refreshed after each use. It gives that clean, firm feeling without any irritation or dryness. I’ll definitely keep it in my routine!!

It worked out
Purchased as a gift for my wife. I never know what to get her for her birthday, So I checked what she viewed on Amazon and there it was! I told her that if she doesn’t want it to send it back I guess! She said that she got a sample and was trying it, and liked it, but she’s very frugal, especially when it comes to spending money on herself. Let me tell you, she’s keeping it and actually Thanked me for getting it for her! Woohoo! (After over 35 years, I finally figured it out:)

Leaves skin really soft
I just purchased my second bottle because it really does work! I just turned 60 so my face has really started to show it’s age. I saw someone on instagram talking about Knu so I decided to look into it. I was impressed by the ingredients and the fact that it’s made in the US so I bought it and 3 months later, I can honestly say that the fine lines are gone and the overall appearance is like night and day. I’m very pleased with this serum.
