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.

Is this real life?

Okay, disclaimer, at the same time I started using this, I stopped all actives and only used my gel moisturizers because my skin has been so sad lately. WHAT ON EARTH THOUGH? After five (ish) days of using this product morning and night, my post-inflammatory erythema is disappearing in some of my older acne spots. My skin is looking more balanced and smooth. Just generally, less inflamed. I'm not sure if a product can even work that fast so maybe it's a fluke, but I'm hooked on this product. A+

I love the product, but please put it in pump bottle

5

I love how even and plump this makes my skin. I wish it came in a pump because the dropper is messy and doesn't get the last bits of product when its almost over. I still give it five stars because the product has had such a positive impact on my skin.

Immediate Results

I LOVE this booster! I have oily skin, large pores, pores are easily congested, and I almost always have (had-before this booster) slightly red skin in acne-prone areas indicating the verge of a breakout. I was concerned using this at first since others said it caused outbreaks. I was shoched to wake up first day after using niamacide booster to see that my face wasn't slightly red anymore! My pores were not congested at all, NO redness, and acne scars from previous outbreak noticeably diminished! After using for a few weeks, my complexion is so much improved that I don't wear makeup daily anymore. This is my new favorite PC product. I find the texture a bit sticky (as in, it doesn't seem to fully absorb, perhaps?), so I only use at night. My night routine is: cleanse, exfoliate (PC Clear), niamacide booster applied directly to skin, PC skin balancing super antioxidant with retinol (the texture of this lessens the stickiness of the niamacide booster and makes face feel smooth again), and skin balancing gel moisturizer. I'm positive the results I see are from the niamacide booster because I added the booster to my night routine later.

One of my Favs

Love this product and can't live without it, BUT hate the consistency. Anything liquid, easily spillabe makes me cringe. I don't like mixing products in a palm of my hand as I feel they get mostly absorbed by the time you apply them to your face. Instead, I put the drops directly on my face which is so tricky and inconvenient and still end up sometimes wasting the product. That said, I always wonder why, oh why, PC came up with a liquid formula for this one? Why not a gel like consistency of something like Peptide Booster? I would be so happy if PC could change that!

Better than salycilic acid. Best skin product.

5

I use Paula's Choice Acne Kit, regular strength. The only kit with salicylic acid I can use. I tried the bestselling salicylic acid product she offers but while it smooths, it is too strong for me and makes my face oilier. This product however, the Niacinamide Booster is the most amazing skin care product for the face, that I have ever used. In one sense I want to tell everyone about it, but then I think we who love this product better keep it more of a secret or someone is going to try to regulate it, turn it into prescription only, or something similar. This product not only smooths the skin, reduces pore size dramatically, but it reduces skin oiliness in a major way. Totally non-irritating. Goes on like drops of water. All those mattifiers, oil control products out there, and all those sales ladies at the cosmetics counter who insist, "you have to moisturize" - even though all of their moisturizers just make acne prone skin worse (of course they never believe you), they all take a backseat to this product. No comparison to anything I've ever used - it is the best.

Best Hydration For Sensitive Skin

5

PC guide recommended this for dry aging skin, delivers extremely well results. Changed from 2% BHA to 10%AHA gel, per guide for dry sensitive skin. I am 63, do not have wrinkles or any skin issues except, dry skin. The first time combining the two product, I woke to improved skin, especially around my eyes. This serum is water like, works well cocktaling with other serums. Used it AM/PM for a few weeks, now PM only. Spilled 2 bottles, wish there was a solution. On auto delivery but always need to buy more before AHA runs out.

One of my all time fav Boosters

So, this is, in my personal opinion, a wonderful product. I have dry/normal type skin. It can be sensitive to products, but not to this one. It's helped close off my pores near my nose and cheeks. I didn't think it actually would! But it did! I am floored and will keep repurchasing this item. Note: it's also helped my acne scar in terms of fading them!

Amazing product!!! please change the PACKAGING

5

I went to get my (only ever!) facial and the gal recommended this for making my pores look smaller and it WORKS. I went about 4-5 months without it and there was a HUGE difference when I was able to buy it again. I even stopped worrying about foundation, my skin looked so good. My only complaint is that I have spilled bottles of this TWICE. It's extremely awkward to get a drop out of the dropper and try and replace the dropper tightly right away because you have product in your hand. Then if you don't remember right then to close the bottle tightly, it can be tipped and all that product is lost!!! And it's not cheap! So please, please put it in a tiny pump that just puts out a couple drops. Please find something different to package it in! Because I love the stuff so much and I can't afford to waste it!!

My favourite thing

5

I love this stuff. It's like a reset for my face that's light, helps add moisture. And in addition to its research-proven anti aging benefits, it brightens, evens things out, reduces pore size and controls oil. I wish it wasn't so expensive, and I keep wanting to switch to the lower priced Cerave AM/PM, but I love this as a serum.
