I started using this product during the day and layering it under my sunscreen. It wasn't bad for that, but I just find using it at night is much more effective. It is a thick enough consistency that it can go on as the last layer of a night-time routine and act as an overnight mask.

I love the BHA liquid exfoliant and use that during the day now, due to its quick absorption. I am not able to use the BHA lotion exfoliant at all, due to my Dimethicone allergy. The gel and liquid products are my GO TO products when i'm battling a break out. I literally wake up with better skin.
