Why is it different?

10% Niacinamide Booster is the first concentrated 10% niacinamide formula blended with natural calming and superior hydrating ingredients to address the frustrating combination of enlarged pores plus visible signs of ageing, such as: uneven skin tone, lack of radiance, rough surface skin texture, redness, and dryness. The results after only a few days will impress you.

What does it do?

Niacinamide is a form of vitamin B3, which research has proven can reduce the appearance of enlarged pores, uneven skin tone, wrinkles, and dry skin. The light-as-water texture is designed to dramatically enhance your skincare while also providing soothing agents to promote visibly calm skin. Antioxidants and skin-replenishing ingredients make this product a multi-tasking must-have solution for all skin types.

How to use

Dispense 2-3 drops into the palm of your hand and then apply to your face. Add a couple more drops if you will also be applying to your neck and chest. During the day, finish with a moisturiser with SPF 15 or greater. Can be applied under the eye area, avoiding the eye itself.

Ratings & Reviews

Amazing stuff!!


I don't know what it is about this product but its awesome! Ive recently added this into my nightly routine and my skin feels better, more plump and luscious, looks better, my big pores around my nose have reduced I dont notice them anymore, its amazing!




I will use this forever!!!


Once I added this to my routine (cleanse, skin balancing toner, 2% BHA liquid, then this niacinamide booster) my pores are getting healthy from the inside out. I'm shocked. I have a handful of super enlarged pores on my nose; even they seem minorly improved. The regular pores on my nose are VERY improved. I really think that sticking with the lighter watery products is working for me as well, thick products clog my pores I guess!




Amazing for skin but also seems to be great for hair?


So I've used this for skin for a while and it's fantastic. However out of curiosity after reading somewhere that niacinamide is good for hair growth, I tried a little on my scalp once a week at night(in the oily areas) then my hair grew like mad and my hairline improved??!! Please consider turning this into a hair growth miracle formula?




This is now an absolute HG product for me


This is now an absolute HG, don't want to go without type of product for me. When I first started using it I noticed a definite decrease in my pore size and improvement in overall skin clarity. I have large pores and prominent sebaceous filaments, and they use to be the first thing I saw when I looked in the mirror. After awhile I think I just forgot how my pores looked before the product, so when I ran out of it about 2 weeks ago I didn't immediately rush to repurchase because I wanted to use up other serums. Cut to a couple of days ago on pay day and I've immediately repurchased. The difference in my skin without the booster is very noticeable to me. My pores stopped being something I really noticed and now they're huge again and that makes my overall skin look so much less uniform and it's less bright. Formulation wise I have found it to be like water, and I mix 2-3 drops with the Calm Repairing Serum. The combination is extremely light and absorbs instantly.




This is amazing!!!


I saw an immediate difference with this product. It's like my skin is so young looking and flawless. I use it every night and add it to a moisturizer because it's a liquid product in a dropper. Honestly it's a miracle. I love love love it!


Provo, UT




I use this product daily, usually just in the mornings but sometimes 2x a day. After my morning cleanse, I apply this in conjunction with my hydrating toner (Kiku high moist). It has made a noticeable difference in skin tone - face looks brighter & smoother (smaller, less noticeable pores). Also helps to fade PIH and lessen the appearance of fine lines. Something I'll definitely keep using :)

Surprisingly effective


I was getting pretty frustrated with enlarged pores on the nose. This combined with BHA and resist ultra light serum were surprisingly effective in reducing the pore size and preventing white heads from coming back.




Great for PIH and pores


I purchased my first bottle in October 2016 and used it sparingly, but did notice a difference when using it. After starting a topical Vitamin C last month, and realizing it broke me out, I gave away the Vitamin C and started using the Niacinamide in place of it. I noticed the difference again, and even a lot lightening in the post inflammatory hyperpinmentation I get from acne. With the recent 20% off sale, I purchased my second bottle. Just in time too since the day I received my package, I used up the last bottle. I tend to only use this is the mornings, and even with once a day, I noticed a difference.

Give it time


I got this back in December and used it once or twice and put it back in my drawer. For whatever reason I pulled it out a month ago and started using it on a daily basis. I have oily skin with large pores that you can see a mile away. After using it once a day, everyday for a month my pores appear much smaller and I'm not getting as oily as I was before. I've also noticed that my skin is softer and looks better overall.




Brilliant formulation


This product is a marvel. I have had huge pores my whole life and this is truly remarkable in that it reduces pores but also soothes the skin and is lightly moisturising. I mix it with moisturisers and it makes my skin look so healthy. I love this.
