This Kiehl’s Niacinamide Serum is a must-have if you have oily or combination skin! It’s super lightweight, absorbs instantly, and noticeably reduces excess oil and shine throughout the day.

It layers beautifully under moisturizer and makeup, and I’ve noticed a real improvement in overall clarity and tone.If you’re dealing with oily skin, breakouts, or dullness, give this a try. It gives that healthy, natural glow without the grease!

I just moved from TX to CO and I kept breaking out. I thought it was because of how dry Colorado was, and I kept moisturizing all that I can. I never thought in my early 30s I would breakout this much. So I did some research and was told how Niacinaminde helps with oily skin. I been using this for few months now and I can clearly see the results. My sebaceous pimples are gone and my skin isnt as oily or breaking out as much! I like how it’s only 5% because I do have sensitive skin!

Ive been using this serum for 2 years now and its been lifesaving for my oily sensitive skin. What makes it amazing? The low amount of ingredients in this product makes this item amazing. As someone who lives in florida this is the best serum for oily skin.

This serum compliments my three-step regimen with a moisturizer and SPF. My skin never looked better without appearing oily but more defined.

I tried this because of 2 reasons. 1 my makeup was melting due to menopause. 2nd was because I wear a mask. It helped my pores some so my makeup didnt get clogged in them.

Very hydrating. Helped easy dryness from using retinol. Love the packaging glass bottle. Made my skin feel soft and is a bit thicker than the ordinary niacinamide but with the money for evening my skin tone.

I love that this is not sticky absorbs well and has no scent whatsoever. Layers with other serums and can be worn under make up.

Item: Kiehl's Ultra Pure High-Potency 5.0% Niacinamide Serum, Concentrated Face Serum - 1 fl ozPrice at time of purchase: $19.40The 2nd day I used Kiehl's Ultra Pure High Potency 5.0% Niacinamide Serum I noticed a difference in the way my foundation looked and felt on my face. Kiehl's is a high quality brand with a worldwide reputation of delivering exceptional products, so I wasn't surprised by the nearly immediate difference I noticed. I expect that with continued use, I'll see even greater results. However, since I am just on Day 2 of using this serum, I can only speak to the benefits thus far. The serum is very thin and lightweight, and absorbs quickly. It was like putting a sheer, smooth canvas on my face after washing and before I put on any other products. First, it helped my daily moisturizer absorb more quickly. My skin looked dewy, but not at all oily. I was happily surprised when I added foundation. Application was smoother than usual and the soft, light dewy look remained, again, with no residual oil and no pilling. The scent is light and neutral. I'm excited to see the effects on my skin with continued use.At less than $20, this serum is a bargain, as it typically sells for upwards of $26.00. Highly recommend!
