    El - Wouldn’t repurchase
    After reading all the reviews I was so excited to try this product! However it left my skin bright red and sore after using. I tried again and the same thing happened. Wouldn’t recommend if you have sensitive skin

    jmac - Ruined my skin
    I am very disappointed in this product. I have been using for 2.5 weeks and I am breaking out like crazy! I feel so hideous and I can't stop the whiteheads and comedones. I am not even halfway through the bottle--I feel like I got ripped off. This is so expensive.

    Customer Care: Hi, and thanks for letting us know of your experience - we're sorry to hear this didn't work for you! We have contacted you in the meantime to explain our return policy.
    Ritu G - I love this as a treatment/booster!
    My skin absolutely loves this! I generally use it after the vitamin C booster, as recommended by PC. I also sometimes use it with my moisturiser to give that extra bit of hydration, especially on colder days!
    50something - First time PC hasn’t worked for me
    I am a PC disciple and wouldn’t use any other products, but this has been a disappointing purchase. I hoped it would help reduce pores but have noticed no change whatsoever. I absolutely love every other PC product i’ve ever bought, such a shame this hasn’t lived up to the expectation and i won’t buy it again.
    Soupie - Best Product Ever
    I am on to my fourth bottle of this product ( each bottle lasts me about 6 months) and absolutely would not be without it. It has significantly reduced my post blemish scarring on my chin. Reduced pore size around my nose and diminished wrinkles around my eyes and on my forehead. It has reduced redness on my cheeks and even my skin textured. This product is a must have and you can add a few drops into whatever serum or moisturiser you are using which makes it very easy to use. One of Paula’s Choice best products.
    Emma - AMAZING!!!
    I literally can not get enough of this product. It has made my open pores less visible and has evened out my skin tone. My skin is now at its best and I’m in my 40s. Wish I had discovered this product 20 years ago!
    eru - Doesn't do anything for me
    I want to like it because I've been using PC for some time but it does nth for me. I went through 1 and a half bottle, decided to return the last one.

    Sophia - Will not be without this product.
    I absolutely love this product! I use it after the Clear BHA exfoliation every morning and evening along with the peptide booster. I always have an extra bottle in my cupboard just in case I run out. I do not want to be without. Does exactly what is says on the 'tin'
    Jen - My New Favourite Product!
    I love Paula's Choice and have used her products for years. But this Niacinamide Booster has now become my most favourite and essential product out of everything I use! Just two drops per night has left my skin super smooth and refined. Please don't ever stop making this!
    tiff - leaves my skin glow
    I use this product in the evening and it leaves my skin glow, moisturised and soft. the pipette is very helpful in administering the right amount.
    ilma - acne pigmentation is gone
    I suffered from acne for years and after a prescription retinol my acne cleared up but i had a lot of red marks from acne so i bought pc 10% niacinamide booster and it helped my marks alot but now i want to buy c15.
    jane - effective
    I like this, I use it day and night with the resist serum. my skin looks great, I think this is the added extra to my skin regime. I can honestly say paulas choice products have saved my skin
    Peony - Smaller pores !
    I have fairly large pores on the side of my nose which definitely needed primer before applying foundation otherwise those pores really show up when foundation is applied . So I thought I would give this booster a try ...at first I used it on its own without mixing with a moisturiser , it stinged my skin a little so I stopped using it , after a while I decided to give it another go but second time round I mixed a couple of drops (it's very watery in texture ) with the paula's choice barrier repair moisturiser and it didn't sting at all . I only use it at night, after a few weeks I started to notice that my pores were looking a lot smaller !!! Although it is a very small bottle a little goes a long way , I find that one drop mixed with two pumps of the moisturiser is really enough for the face and neck . paula's choice products have been a game changer for me , from having almost perfect skin throughout my 20s I started getting breakouts due to hormonal changes (I'd stopped taking the pill at 30) there were deep painful cysts and spots continually popping up ... but after going to doctors asking for help (prescribed retinoid) I also did a little research myself and stumbled upon paula's choice website and bought both her books . After reading them I realised I was putting too much alcohol products on my skin which made the breakouts even worse ! I now only use fragrance free alcohol free products ! Hard to find so most of my skin care is from paula's choice ! I used to wear bare minerals blemish remedy foundation which is quite heavy coverage then I progressed slowly to the bare minerals original and now I'm just using CC cream and only where it's needed and it's all thanks to paula's choice ! My skin still has a while to go yet to being as great as it was in my 20s but it's getting there ! Thank you Paula ! Only wish she had a store here in the U.K.! Although I agree with the other reviewer that there should be a sample bottle of this booster for people to try as the sachets are really annoying especially if the product is very watery as in this case and also if it was in a smaller bottle you can take it on holiday with you !
    Tracy - Ineffective
    Used a whole bottle and didn't notice any difference to my skin whatsoever. Still searching for a product that WILL actually have an effect on me; my skin seems to be immune to everything!

    Laura - Not enough in a trail size to comment...
    I get on really well with skin care which has niancinamide listed as an ingredient. I like the Olay products which have them listed within the top few and notice a difference so I was really interested to see that PC offered it in more of a purer form.
    I ordered two sachets. The consistency is that of water. A clear colourless and odour free liquid. I applied it directly to my face. It didn't feel of anything given it's consistency - so I added my usual moisturisers. The thing with these - is - you don't get enough in a sachet to be able to comment really - you'd need to order about ten. It would be better if it was offered in a smaller version of the large.
    I wouldn't purchase this for £38 without a decent trial size and there aren't enough reviews listed with people's thoughts. I've given it three stars as I'm neutral.

    Can I combine 10% Niacinamide Booster with other Paula's Choice products containing niacinamide?

    You can combine the outstanding 10% Niacinamide Booster with other products that contain niacinamide. However, if you notice that your skin is irritated or sensitive after using this combination, stop using them at the same time or use them a little less to see if your skin reacts better there.

    Can I use 10% Niacinamide Booster around my eyes?

    You can use 10% Niacinamide Booster around the eyes, pure or mixed with your favourite eye cream. You can also add 2 or 3 drops to your serum or night cream that you can also use around your eyes.

    Can I use 10% Niacinamide Booster while pregnant or breastfeeding?

    Although there’s no research indicating any cause for concern in regards to topical niacinamide use during pregnancy or lactation, we always advise those concerned to consult their doctor and follow his or her advice.
