Fantastic!

I love the way this concentrate makes my skin look and feel. It's moisturized and I felt like the fine lines were softer after using it for a week. I ordered a full sized bottle!

Nice cream
Sampled

Sample wasn't really large enough to get a good idea of how this would work but it did feel nice going on and I think some fine lines may have been reduced. Smelled great too.

Love this serum

The serum isn't greasy because it has a creamy consistency which I love. I've been using this everyday and plan to continue!

Great product

I wouldn't say I am old but 35 isn't 20's. This is a good product, it works so far and there is no smell to it which is a plus

At first this stung m6 sensitive skin. Be advised don't get to close to your eyes. Made mine water a bit. It made my skin feel very hydrated. Smoothed wrinkles just a bit.

Works

Feels very greasy at first but absorbs in skin instantly. I really feel like this worked. It made my skin feel soft and hydrated without feeling greasy.

These types of samples don't really work well for oily skin. Its pretty difficult to see any change with the amount of sample provided. I wouldn't both with it.
