Niacinamide 20% Concentrate Serum – High-Strength Blemish Control, Pore Minimizer, and Skin Tone Corrector – Pure Ingredient for Smooth, Even Complexion – 30ml

I love this serum. It’s great to add to any part of your skincare. It is a great value for money because you can add it to your other skincare items and not have to use another separate niacinamide serum. It absorbs quickly and it is very effective. Niacinamide is moisturizing to the skin and helps skin build its own collagen and many other things.

Why did you pick this product vs others?:its ok - worked better when bottle new?

Great for Brightening and Smoothing SkinI've been using this 20% Niacinamide serum for a few weeks and I'm really happy with the results. It helps even out my skin tone and makes my skin feel smoother and more hydrated. The texture is lightweight and absorbs quickly without being sticky. Great value for the price!

I have been using for a week and can already tell the difference in my skin tone and discolorations. Very exciting!

I’ve used niacinamide for years, but I had never seen such a high concentration so I was excited to try this. I used this in place of my old niacinamide serum & made sure that was the only change I made to my routine. I ended up using it 2 times per day & had absolutely no issue with it. My skin can be somewhat sensitive, but this did not bother me in the slightest. I didn’t notice much difference after going through the whole bottle either. I thought that considering this product was 2 times more concentrated than any one I had ever used, I was surprised that was the case.

I bought this to create my own serum. I had to do some calculations to make an 8% solution mixed with bacteriostatic water. I tried to mix in some ponds lotion to thicken it by shaking it together, however they are not compatible that way so I don't recommend trying that. It might mix if done in a beaker and a frother is used. I decided later that it's for the best as I want to make sure the lotion doesn't prevent it from fully penetrating my skin.I've used it twice a day for about a month and I definitely notice a different on my age spots around my eyes and on my hands. I don't see anything happening to shrink my pores or help with blackheads on my nose.I recommend starting with light applications until your skin gets used to the niacinamide and make sure you don't use it with another product containing niacinamide. I did that the other day with a new overnight moisturizing mask and when it starting burning, I checked the mask ingredients and sure enough there was some sneaky niacinamide in there. The burning went away after about 5 minutes and wasn't terrible, just be safe with it.

I’ve been using this with moisturizer for a few weeks now and it definitely boosted the hydration in my face. Soft and silky at age 68, I’m loving it!
