Kiehls ultra pure high potency niacin-amide serum is great for my oily skin. This serum is very thin and lightweight. I like that it absorbs quickly into the skin and although it looks like an oily it's not oily at all it actually reduces oil in my tzone which is great. I have seen my skin get clearer and my skin texture has improved a lot. This serum also minimizes the appearance of pores!
I'll keep buying this one, permanent product in my skincare!

I have combination skin that leans more towards the oily side too often, so this Kiehls Ultra Pure Niacinamide serum works amazingly well to keep me from looking shiny and oily throughout the day. No need to carry blotching papers in my bag and make multiple bathroom trips with this serum keeping the shine at bay. I enjoy this serum and it's become a staple in my skincare.

This serum have a good texture, it is not too thick but medium. So, it absurds quickly. However, you need to use it longer than 6 months to see its effectiveness on your skin.
