Another great product from Khiel's

Before using the Khiel's 5% Niacinamide serum, my go-to niacinamide serum was always the First Aid Beauty serum. I liked the way it smelled, how well it went on to the skin, how well it blended with all my other serums (including my exfoliating serums like my lactic acid serum), and how my skin looked hydrated and primed after every use. BUT let me tell you, this Khiel's serum is ALL of that and more! Not only is the Khiel's serum more potent, it also controls oil. And as a person with oily skin, especially forehead, this serum is a secret tool in my arsenal that shouldn't really be a secret.

I've been using Kiehl's Ultra-Pure High-Potency Serum 5% Niacinamide for almost a month now, and I cannot necessarily tell that I've been using it. For starters, I have combination skin that tends to be more oily in my t-zone and forehead. In my skincare routine, I use this after my toner and before my moisturizer or sunscreen in the morning. I would use it both in the morning and at night, and I feel like I haven't seen a huge difference. There have been a few days when my skin has looked pretty good and other days when my skin was struggling.

The one thing that I did like about the Kiehl's Ultra-Pure High-Potency Serum with 5% Niacinamide is that compared to one other niacinamide serum that I've tried in the past, this one did not irritate my skin or make my skin burn, so I know that it it isn't necessarily hurting my skin in any way. It just also isn't helping. I haven't seen a huge difference in my hyperpigmentation or dark spots and my skin still feels oily throughout the day and night when I use this. I think it's worth giving a try, but I don't think it is something I plan to refill on.

New skin, new me

I am shocked by how well this product works. I have dabbled in skin serums, oils, and creams for years, but I have never found anything that changed my skin texture the way this product has. Prior to using this, I had little skin colored bumps around my cheekbones that I couldn't seem to get rid of. They were hardly noticeable with makeup, but I was still self conscious about the texture of my skin. During the first week of using this serum, I noticed the bumps were becoming more noticeable (red) and I thought I may be allergic to the serum. I decided to push through another week and see if anything changed - and boy did it! I woke up one morning and my skin was almost entirely clear of the little bumps.

Nice serum but silicone scent
8 February 2023

This is an oil minimizing 5% niacinamide serum formulated with only 10 ingredients. You apply 4-5 drops to clean dry skin in both the morning and evening. The bottle is thick glass which is really nice and the dropper itself is glass too so the product itself is cool when applied. Both are recyclable. It claims to visibly reduce imperfections and excess oil as well as minimizing shine and visibly soothing skin. I have not been using it long enough to say it does. I do have sensitive skin though and this did work for my sensitive skin meaning the niacinamide it not too strong and could work for you if you have a similar skin type. I'm also oily and acne prone.

It is very silicone gel smelling and it also smells like it could be expired but it isn't. If you need an affordable serum and you're specifically looking for a niacinamide serum I think this would be a good one to try.

Plump and toned skin

I use retinol nightly and benzoyl peroxide in the day, both of which have dried my face out, causing more texture, but also ruined my moisture barrier. I have started to use this kiehl's niacinamide with my morning and nightly face ritual and I have noticed a big difference after a week of use. My texture has smoothed out as well as my tone. My skin also feels more plump and full. Maybe it's because my pores look smaller? I don't know the ins and outs of niacinamide but this stuff is magic. I would suggest anyone to use this product. The dropper is perfect for adding just the right amount of product to my skin. The formula is non irritating and rubs in smooth with no piling.

Wish my skin liked it

I love the jar and dropper on this. It feels very well made. The product itself feels like any other good quality hyaluronic acid serum product, but of course this one is niacinamide. It goes on nicely and dries down to a nice tacky finish (which I like under my makeup and before bed). I have dry skin, so I was scared this oil-minimizing product would dry me out, but instead my skin was so hydrated! Unfortunately though, this broke me out. The areas of my skin that weren't growing giant pimples looked supple and glowing, but I can't ignore the areas that it spurred up angry acne. I don't believe that it was purging because I had JUST finished the purging process with another product and gotten my skin healthy and clear. It must just be a specific ingredient my skin ... MoreI love the jar and dropper on this. It feels very well made.

Works Well
15 February 2023

I was so excited to try this serum! I will first of all say that I love it how works for all skin types and is gentle on the skin. The texture is thin but also has a sticky or thick kind of feeling to it on my hands but is easy to apply on my face. This feels kind of sticky when applied but is also lightweight and absorbs pretty quickly to the skin. I noticed after some time that it most definitely helps reduce shine and leaves a natural glow instead but you can also still do your normal skincare routine over this with great results. I like the strong bottle and how the dropper works well. I don't notice a scent or anything off putting and don't need too many drops each use. I would say over time this can give great results because just over a couple of weeks I ... MoreI was so excited to try this serum! I will first of all say that I love it how works for all skin types and is gentle on the skin.

i am absolutely loving this serum! i have very oily skin and this has really been helping reduce that excess oil and shine on my face. it's so gentle on my skin, i think it's perfect for sensitive skin. i love that it doesn't contain any harsh ingredients or fragrances that can be irritating to the skin, the ingredients are amazing! this doesn't smell like much which i really like. it has a very light scent to it that i can barely smell. the texture is so nice and lightweight. it absorbs into the skin easily and quickly. it leaves my skin feeling soft and hydrated and looking clean and naturally glowy without looking greasy and oily. i love the dropper and how easy it is to apply the product with it. i've been using this every night before applying my moisturizer ... Morei am absolutely loving this serum! i have very oily skin and this has really been helping reduce that excess oil and shine on my face. it's so gentle on my skin, i think it's perfect for sensitive skin. i love that it doesn't contain any harsh ingredients or fragrances that can be irritating to the skin, the ingredients are amazing! this doesn't smell like much which i really like. it has a very light scent to it that i can barely smell. the texture is so nice and lightweight. it absorbs into the skin easily and quickly. it leaves my skin feeling soft and hydrated and looking clean and naturally glowy without looking greasy and oily. i love the dropper and how easy it is to apply the product with it. i've been using this every night before applying my moisturizer and i've been loving the results so far. i want to see what it does for my pores in the long run, so far this is a great serum. im going to start applying this two times a day to see better results!
