So far so good!  I've only been using it for a week so I haven't had a chance to see much for results yet ... However, I know that niacimide works well for my skin, so since that's the main ingredient here, I know this will work well too!

This is one of the very few drugstore products I've ever seen with such a high concentration of niacinamide! 
Differin pretty much never disappoints anyway though. 
They're one of the few drugstore products that actually focuses on actives and PROVEN ingredients, instead of just gimmicks and word-play like most of the others.
