  1. Emily Toms

    Formula is nice and feels high quality but it caused extensive cystic acne on my cheeks. Was probably just a poor reaction on my specific skin

  2. C Carr

    I like the smooth texture of this product. It is easy to apply and absorbs quickly. I have not had any irritation. I would purchase again.

  3. Mikayla Young

    Absolutely in love with this product. You can use it by itself or mix it with your moisturizer which is what I do myself. Definitely helps with brightening the skin

  4. Nicole

    It’s not a lot quantity but quality-wise- tops the charts. Sometimes when I’m tired, I just throw this on my face, neck and chest, and my skin always looks better in the morning. I believe it has made achieving my skin goals a lot easier. I don’t have perfect skin, but it does help with the break-outs. It’s like an all-in-one treatment for skin issues. Even with the expense and small quantity, I recommend anyone to try this, I wear it day and night!

    This is my sixth bottle, it’s never off of my shelf. This is the first time I purchased PC products from Amazon.

  6. Sam

    This is my second bottle of PC 20% Niacinamide prior to which I used the PC 10% Niacinamide.

    It worked for me; looking at my face, it was more effective than the 10%. After having used 10% for more than a year, I seemed to have hit a plateau as far as post-inflammatory hyperpigmentation was concerned; swapping to the 20% was a definite improvement. It wasn’t a change noticed overnight or even a week, it took me a little over a month with my first bottle before noticing any difference. Your mileage may, of course, vary.

    That said, please use it wisely. Do not jump into 20% Niacinamide from zero. As with all skincare products, especially actives, ease into it. Patch test first. For the first few applications, mix with moisturizer for a less harsh introduction before transitioning to direct application.
    I see quite a few people mentioning breakouts upon first application: for some that’s inevitable, for others completely avoidable. Do not shock your system with such a high concentration right off the bat.

    Price: It’s highway robbery, but that comes down to personal preference and means. My household is one where PC is popular; for even the most frequent user, a bottle lasts anywhere between 2-3 months. The decision is yours.

    Love it!

    I have used this serum for the last year, My skin is clearer and looks younger!
