SOOTHING AND NON-DRYING: Beneficial for acne prone skin and clogged pores. This serum is non-drying and designed to help to reduce signs of moisture loss caused by a weak skin barrier function.
PROMOTE SMOOTH AND EVEN SKIN: This balancing formula is rich in Niacinamide (10%), also known as B3, and can be very helpful for those suffering from breakouts, uneven skin tone, enlarged pores, and dull texture.
PERFECT ADDITION TO YOUR BEAUTY REGIMEN: Apply a few drops to your skin in the morning and at night before oils, moisturizers, and creams. Our serum is powerful enough to bring results and gentle enough for daily use.
GENTLE ENOUGH FOR ALL SKIN TYPES: This serum is suitable for all skin types, but can be particularly beneficial for those with combination/oily skin. Our serum has a pH of 7.1, is fragrance-free, and was never tested on animals. Since everyone’s skin is unique, we recommend performing a patch test before using this product to ensure compatibility and avoid any potential reactions.

Great stuff
This really works was my last resort tried it and absolutely love it. Shrunk pores, even out skin tone and smoother face soft and gentle. Great product
Rhonda R Johnson –
Effective and affordable!
This niacinamide serum is super affordable and actually works to moisturize and hydrate my skin. It helped smooth out my skin and fade some dark spots without any irritation. Lightweight, soaks in fast, and layers well. Can’t go wrong with this on
Jamie Baker –
Good quality
I haven’t ever tried niacinamide but I know it helps with skin texture issues. The ingredients are great! I’ve only used it once this morning so I will see if it helps with skin texture issues and dark spots! Not oily at all it absorbs fast.Update: after a month of using this religiously (on my second bottle) the pores on my face have reduced dramatically as well as frequency of breakouts. Also a dark spot on my forehead has lightened a lot. I’ll be using this forever!

Very good!
I am 44yrs. I’ve been using this product well over a year. It gives my skin a glassy glow & makes it soft to the touch! Makes my pores appear smaller too

Best best best!!!!
Hands down the best niacinamide serum. Doesn’t irritate my skin. I have bad adult acne. And this keeps me relatively clear (except for those pesky PMS weeks) but it helps with my oiliness of my skin keeps it hydrated and looking nice
Holly Valuet –

Views on product
This is a good product to add to your skincare. When I use it, it makes my skin look smooth. I can’t explain the scent but it doesn’t smell bad. Also, after using it, my skin feels dry but not dehydrated, so I moisturize after. I guess it adds a glow to my face, it just makes my skin feel and look pretty. Doesn’t irritate my skin or anything, would definitely recommend buying

My dark-spot started to fade slowly…

I’ve replaced some very expensive brands with this beauty. Excellent value for money, does what it says – is great for my pores and smoothness, I’ve had clearer skin too.

Reduced pores!

Sowohl ich im Gesicht als auch mein Freund an der Brust (da ich mich beim Schlafen angeschmiegt habe) haben davon richtig schlimmen Ausschlag bekommen. Fehlkauf!
Athena Bennett –
Because of the lack of positive difference in the before and after photo, I almost didn’t buy it. Still, I trusted the science and did. Oh my god- Absolutely awesome. Best product for my skin thus far- of course, must be used with cleanser, moisturizer, and sunscreen. If you’re one of the people who wants glass skin like the girls you see on tik tok… this is the it.Companies that spend their budget on chemistry instead of marketing >
