Verified Buyer

I ABSOLUTELY love this serum. It makes my skin feel so smooth & I think it does reduce the appearance of fine lines. I should have started using it immediately the 1st time I bought it instead of waiting to finish products purchased before it. It immediately became my favorite! I've eliminated so many products cluttering my cabinet by using this one product. LOVE MY KNU YOU ANTI-AGING FACE LIFT SERUM!!

I love this serum it’s the best. It instantly tightens your face and neck. I love the way it makes me look. I use this and the face and neck cream together also by Micheal Todd I love the new bottle it comes in.

Verified Buyer

My face feels and looks so luxurious. I can’t believe it I love how my skin looks so much younger.

Verified Buyer

This serum is hydrating and long lasting. Feels comforting on the skin. It is winter here in California so I’m not sure what it will be like in the dryness of the summer.

Verified Buyer

I just started using this again after trying to find the cream and could not. I love the serum and cream for my 70’s face. I used to use the KNU SERUM for years and people still tell me I don’t look my age!

Verified Buyer

I have some rough facial skin and this product was very useful. In one overnight application it did the job and now I am using it constantly.

Verified Buyer

"I've been using the KNU Serum for many years!! I feel It's the best Serum for aging skin, and believe me I've tried many many products over the years!!!

Now if you would bring back the KNU anti-aging Cream I'd be the happiest aging Woman on the planet!!! xo"
