Why did you pick this product vs others?:skin plump next AM - even after astringent

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

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!

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 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.

Great skin care option. I use it twice a day and a little goes a long way. No scent really. It’s clear and goes on easily. No residue and doesn’t feel sticky at all.My star ratings are based as follows:5⭐️ - love it, can’t live without it. Outstanding and amazing.4⭐️ - pretty great, no major flaws.3⭐️ - got some issues going on.2⭐️ - pretty flawed product.1⭐️ - don’t waste your time or money. Just not worth it.

I have been using this niacinamide serum for about 2 weeks. It absorbs fast into my skin and leaves it feeling hydrated without feeling sticky or greasy. This is my first time using 20% Niacinamide, so I can’t compare its effectiveness to others, but I am happy with it so far. I must say that this product’s claim to provide hydration without leaving the skin feeling sticky or greasy is truly accurate, which is a huge plus in my book. I think this product does a great job, and I am happy with my this and will continue to use it.Made in Korea. If you are new to niacinamide, I would recommend starting with a lower concentration first.
