10% Niacinamide Serum 30ml, AM/PM Skincare, Reduces Excess Oil, Anti-Blemish Skincare, Vegan Friendly, Suitable For All Skin Types

I am a woman in my 30s who has always had very oily skin, especially in the t-zone. I used Niacinamide from another brand in the past and didn't notice much difference in my skin and just felt sticky after, but I thought I'd try this as I've had great results with other Inkey products. I was tempted by the 20%, but thought I'd play it safe and see how I got on with the 10% first. I have used this at least once a day, in the evening (also in the morning if I'm going out, otherwise I'm not bothering with any skin care if I'm honest), for about 2 weeks now. While it does have a slight tackiness straight after application, I've found this goes quickly. The only time it didn't, I had used more than the recommended amount. It absorbs quickly and has no smell. I can honestly say it's made a huge difference to my skin. I am no longer able to run my finger across my nose and able to see the thick oil on my finger afterwards, THAT'S how oily my skin was. I do think my pores are visibly reduced too, they're clearly still there but they don't look instantly obvious. It didn't dry my skin out and has been a great addition to my simple skincare routine (cleanse, hyaluronic acid, niacinamide + moisturiser). I would definitely recommend this to fellow oily skinned people. There aren't instant results but after a week of regular use I already noticed results that continue to improve with time.

I’ve tried countless serums over the years, but The Inkey List Niacinamide 20% Supersolution truly stands out. My skin tends to be oily with occasional redness and uneven texture — this product tackled all of that within just a couple of weeks. The formula is lightweight, absorbs quickly, and doesn’t leave a sticky residue. Despite the high 20% concentration, I experienced no irritation — just calmer, smoother, more balanced skin. The redness around my cheeks and nose noticeably reduced, and my pores looked tighter as well. I also appreciate that it’s fragrance-free and designed for sensitive or reactive skin types. It layers beautifully under moisturizer and makeup, and the price point is excellent for the quality and results. If you're dealing with oily skin, enlarged pores, or redness, I highly recommend giving this a try. It’s become a staple in my routine!

Pretty decent niacinamide serum, but has a tacky feel and leaves white patches if you don’t put it on with strict moderation. Also getting it out ot the tube can be a challenge, even when it is nearly full. These challenges put me off using it. Still, pretty good for oily skin. I always wake up with a less shiny t-zone when I put this on at night. Even controls the oil a tiny bit under makeup (although don’t expect miracles). I feel like it helps refine skin a bit over time by moderating oil production, and doesn’t cause too much sensitivity.

Love this serum. I’ve got quite oily skin, I use before make up and it stays put with no oily nose. I don’t find the need for a primer since finding this. Buy on subscription.

Great item - made my makeup look flawless and received many compliments

I really don’t like the container (a tube). The dosing is poor and it dispenses too much product at once, which leads to waste because it can’t all be absorbed. As a result, the product ends up being expensive. It should ideally be a bottle with a pump.

The Inkey List Niacinamide 20% Serum has probably been one of the best of this formula i have used so far. I like that it comes in a tube it tends to dispense just the right amount for me each time, You can see in the picture the look and consistency of it and this is the exact amount i use for my face, I have an oily T-Zone and quite enlarged pores especially on my nose so i do concentrate mainly on that area, but using all over my face is best as we have pores all over and some of them are not so visible but still secrete oil for example the chin and above the upper lips under the nose. When applying first rub it a little with your fingers together with both hands then in circular movements starting on your problem area then working the same way on the rest of the face, try not to overdo that part then gently pat with your fingers into your face and leave it so it can get to work. Because this serum is a little thicker then make sure your other serums are applied in order of thinnest to thickest. I like that it is fragrance free too because i think many serums that have a pleasant fragrance are just a chemical additive just to attract you thinking it will be more luxurious, the lesser the ingredients the better it will be look for the main ingredient in the top 5. Great price and well worth trying i recommend this product.

Good, does help my oily skin a little but not completley No perfume or scent which i also like so worth using Absorbs well and is very lightweight and no residue on your skin.
