Skinsation

I felt like my skin dealt smoother and actually felt firmer. I shared done with my girlfriend and she loved it to. She ended up buying it but not from Birchbox, so I pushed her to sign up.

Very smooth texture but I'm not sure it does anything
Sampled

The smell of this is not very pleasant but it smells like it should do the job. The consistency is very smooth however I don't think it got rid of any fine lines that I have on my forehead head. I gave it a shot for about a week but I feel it would take a larger sample to notice any sort or difference if anything. Not sure that I would spend the money to try it. On a side note, I do have sensitive skin and this did not aggravate it.

This product works really well and smells good but not over powering. Works great with the lifting serum by the same company.

Seems good
Sampled

I use a lot of good products so it's hard to really determine if it did much for me. But it seemed fine. I like the idea of vitamin C in my serums. It's in lots of documentation lately the positive powers of vitamin C on our skin. I will keep using it and see.

Great moisturizer, not greasy, absorbs quickly and is not heavily perfumed. Skin looked great the next day, brighter.Will definitely look at their other products.
