Additional Information

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 aging, 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 moisturizer with SPF 30 or greater. Can be applied under the eye area, avoiding the eye itself.

Ratings & Reviews



I've been using this product for 6 weeks for large pores. I've seen no improvement at all. I've been using PC since 1996 and this is the first product of hers that failed. Total disappointment

Very harsh and wrecked my non-sensitive skin


I have suffered from extremely oily skin and large pores most my teenage and adult life. After using Paula's choice products for over a year (Skin balancing line and Resist for oily/normal skin) I have noticed a drastic improvement in both oil control and pore size. Needless to say, when I saw this product advertised as a pore shrinking miracle, I had to try it. Immediately after using it, I noticed little bumps appearing on my face the next day and overall my skin texture was a lot rougher. I thought this was my skin adjusting to the product (which is almost never necessary - I have oily, but extremely resilient skin). I continued to use for a week, and unfortunately my skin continued to look dull, lifeless, scalier and dotted with white heads. I went to do a facial yesterday and my facial lady said she had never seen my skin so dry yet with lots of white head bumps. This is saying something considering I typically have extremely oily skin. This product dried it out AND plugged my pores. This was the only product change I made to my skin care routine, and my skin starting worsening the day right after I used it. Last night I discontinued usage and my skin immediately looked better. No question about it, this product is the culprit. I had such high hopes for this and I really wanted to love it but unfortunately it just wrecked my skin - I don't have sensitive skin either. I wish I bought a sample - I live in Canada so it'd cost me quite a bit return this bottle, I'm pretty much out of pocket for an expensive product that my skin really hated. I highly suggest if you're interested in this product to get a sample rather than a bottle to start.

damages sensitive skin


This product caused my skin to become dry, red, flakey. Due to the exceedingly glowing reviews,I continued using it thinking maybe it was one of those situations where it has to get worse before it gets better. When I started getting strange cysts in addition, I finally gave up and stopped using it. Paula's Choice was good about taking back the product and issuing me refund, but unfortunately my skin has still not recovered and it has now been a few months since I discontinued use. I don't know how to heal my skin from this.



No effect on pores and blackheds


I've used this product for the past 2-3 weeks every evening. I mainly wanted to minimize the size of my pores and fight blackheads. I've hardly seen any results so far... :( Really disappointed. I've started to include BHA 1% Calm once or twice a week (my skin is extremely sensitive). I hope this will have some effect.




too harsh


I had such high hopes for this product. I purchased it to treat enlarged pores and uneven skin tone. Initially it did appear to reduce pore size, and I thought it was great. However, within a short time that benefit seemed to disappear and the product was causing my skin to become very dry, peely, flaky, and splotchy red. I had to stop using the product and I returned it. I later learned that niacinamide can have these very effects on sensitive skin, which I have. I wish it was made more clear before I purchased it that many with sensitive skin can have a bad reaction. It's been 10 days since I'm stopped using the product and my skin has still not fully recovered. The red splotchiness still remains.

Immediate difference!


Have seen an immediate response from my skin since I have begun using this product. I mix it with my moisturizer in the morning and evening. Have seen a measurable shrinkage in my pores. Not too harsh on my skin. Use in combination with Brightness Essence.



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!

Did nothing


I bought this product for PIH. It did nothing as far as getting rid of it. Plus it's itchy and sticky on my skin. Also their 100% money back claim is not entirely true. Its true if you return it in 60 days, which doesn't really make sense because it takes at least 60 days to see if a product works or not. So once you realize it's not working, you're out of luck. I'm really annoyed by this and will not be ordering from this company again.


New York




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 :)

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.
