Not the strongest retinol, but nice, not drying. I use it daily, because it is not so strong, and my skin is smoother, firmer. Overpriced for what it is, but I like it.

Doesn't irritate and brightens my skin. The color of moonbeam serum is bright yellow but I think it's okay as long as you apply retinol serum before going to sleep. Highly recommend, this product makes my skin better.

As the title says, good retinoid serum, but to be honest most retinoids will perform like this one. The emollient base is nice, but I prefer a lightweight retinol serum.
