SenAllis Cosmetics Double Pack of 2 Fl oz (120mL) Niacinamide Serum 12% Plus 2% Zinc PCA, Hyaluronic Acid, Balances Oil Production, Fight Against Signs of Aging Such As Wrinkles, Fine Lines

Makes my skin feel moisturized and smoother. It really is a good base & helps spread another face cream over my face that I use in my face care routine. It has only a very light smell so pleasant. I am surprised how long this seems to last, it goes a long way. I think it is good, It is not as thick as another one I have used, but I think it helps make my face to appear smoother and fell softer.

I am 30 and have had acne and dark spots for 20 years. I cannot believe how much this stuff has helped my face in less than a week, applying once per day after shower, under light moisturizer (Simple is great and so is Target brand Smartly moisturizer, both limited ingredient for sensitive skin).The serum is clear and odorless. It dries quickly and is not greasy at all. Very pleased with the amount for the price (I paid $4.50 for 2 bottles 2 oz each, so 4 oz total). try it out.

I’ve ordered a few bottles now and very pleased with the quality. Great value for the price. I use 2x a day, layering under SPF in the am, and over prescription topicals in the pm. Doesn’t seem to pill on my face (tho does sometimes on my chest if I just wiped with micellar water). Absorbs nicely. Not sure if I see any lightening results as I use a number of other products but this doesn’t make me break out and feels nice on my skin! Def plan to continue buying.

This serum is amazing. I have been struggling with impetigo for 6+ months, the scarring to my chin has been horrible, to the point my physician suggested going to a dermatologist for further treatment, which can be expensive. A friend who is in holistic medicine suggested this product to me. From the very first use, i woke up to smooth skin on my chin and face, and it took the insane itch away. Day two and three, it was even smoother and i could see the scarring slightly fading. I'm so excited about this, and it has worked better than the antibiotics and ointments that i was prescribed. I will definitely be purchasing more in the future and update this review on my results in a few weeks!!

I've been using this product for about a year and a half and although at first glance the results are only slightly noticeable, compared to pictures from 10 years ago my skin seems to have aged backwards. Note this might not work if you have deep creases but it's great for fine lines, uneven texture or tone, or in my case a large tan birthmark on my cheek. My skin looks more even and tight without looking phony. And the price point is pretty amazing.

After a week's 2x daily use this hasn't been at all drying or irritating, my skin texture is a little smoother and my pores seem less noticeable. Great value for $. Thick consistency, spreads easily, soaks in fairly quickly, and plays well with my Neutrogena hydro boost gel-cream moisturizer. Unfortunately, this tends to pill up and shed off when I use anything else over it. So I try to wait a few minutes before applying facial oil or sunscreen, and even then I have to pat those in carefully vs smoothing on. I can't use this under makeup. To be honest though, The Ordinary niacinamide+zinc has the same textural issues but with less % strength and less oz. per bottle, so overall I'm pleased with this brand.

I have been using this product twice daily for about a week and am very pleased with my purchase! I feel that overall my texture is smoother and my pores are less noticeable though not yet invisible. I tend towards oil and shine and have not had a problem at all with using this either alone or under make up. It feels thick out of the bottle but quickly dries to an unnoticeable (and not shiny) finish. I am able to cover my face with one drop so I expect this bottle to last quite awhile. I was skeptical about the low price but figured I had nothing to lose by giving it a try. I will definitely purchase again.

This moisturizer is really worth the money. While this lightweight serum moisturizes your skin it takes care of your dark spots at the same time. It absorbs in a few scond without any greasy feeling. My skin looks smoother using this serum only for 10 days. I also tried on my dry overprocessed hair after a little research and it doesn't wait my hair down and my hair doesn't look so frizzy and damaged anymore. My stylist wanted to cut it and I can't wait to see her face next time. I definitely recommend this product!
