Love this product

I have very sensitive skin so I was reluctant to use a retinol product, but this product is perfect for my skin type. I use it at night on my face after cleansing and before applying my night time moisturizer.

This serum has never irritated my skin and goes on very smoothly. I love the way it leaves my skin feeling smooth and refreshed. I have found that since using it my facial skin looks healthier and more even toned. I even use it on my neck and décolletage without experiencing any irritation. In the past when I tried retinol on my neck it would cause itching and redness. But this product does not cause any irritation at all.

I bought this product in a dual pack from Costco - it's one of the normally higher priced products that I would never pay full price for.
Very dissappointed. First it has a faint coffee smell - not really a smell I want on my face. Packaging is horrible - printing is so small its hard to read, and there are really no directions for use - should it go on before moisturizer, after moisturizer etc ....
Saw no noticable difference in skin at all
Not worth it, even from Costco.
