I used this both in the evenings and mornings under makeup. I thought it was a nice light moisturizer. There was little to no smell but I prefer that. I would want to use this longer to say it works but I know I didn't dry out at all when I used it

Never thought about using a product like this but I've been trying it out and i can see a difference. Only problem is that it has a bit of a medicinal smell.

worked immediately

I used this on my forehead where I have been getting a line from squinching my brow. It worked really well after just a few uses. The ingredients looked simple so I was pretty surprised.

Loved it!

I've always wanted to try this brand so I was excited to see it in my BB this month...I haven't been using it long enough to tell if it has improved my skin but it has a really nice light scent and feels good on my skin...I will definitely finish my sample!

Not sure it is quite for me
Sampled

It's a nice but not quite sure if it is really working and taking wrinkles away... the more wrinkles repairs I use, I feel, the more wrinkles I get, as it seems the less wrinkle products I use the less wrinkles noticed or seem to appear. Feels nice though. Maybe when i am in my 50s. But for now, the regimen I use seems to be working okay. Haven't found that miracle yet.
