Visible results

This serum is light weighted and absorbed quickly into my deep layer of skin. It helps to smooth my skin and make my fine lines less visible. It has a non sticky formula and the results are visible in just a couple of weeks. I can definitely see my skin texture is improved and my skin looks glowing naturally. It works great for my 40’s skin. I provided my feedback after I received a special deal on this product.

A serum that actually makes you look youthful!!

I have tried so many anti-aging products in the past that were just a waste of money, but not The Serum by Timeline Nutrition. This serum is definitely “youth in a bottle” and it actually works!! I was so surprised by the results. It goes on easily with a dropper and smooths into your skin quickly. A little goes a long way with this serum so the bottle will last a while. It is light-weight, and it doesn’t leave your skin feeling sticky or greasy at all. It leaves your skin feeling silky smooth and hydrated, yet it doesn’t cause you to break out. You can instantly feel your skin tightening once you put it on and it looks like your fine lines and wrinkles just fade away. After I turned 40, I started trying so many different products to help me keep my youthful appearance and I’m so glad I finally found one that works! I provided my feedback after I received a special deal on this product.

Holy hydration!

This is like a giant drink of water for your skin! I saw improvement in my hydration levels after the first day! I can definitely tell some of my fine lines are more plump. And I feel like my cheeks and forehead are a little more lifted. I was hoping for some more dramatic results in my neck, but with continued use I may get that. This stuff is pretty fantastic. If you can afford the price point, and need some serious hydration, this is for you! I definitely see improvement in my dark circles under my eyes, and overall puffiness off the face. I provided my honest feedback after I received a special deal on this product.
