10% Niacinamide booster

Used the whole bottle... didnt feel any real difference

Good for pigmented skin ..I have used this product about 6 months .After getting good result so I give this product 5 stars . I have used with this PAULA CHOICE'S AZELAIC SERUM also 👍👍

TAKE MY MONEY, PLEASE & THANK YOU! LOL! Okay, bare with me, this will be a detailed, in-depth, review! Which I don't do often, but this deserves one! Because I have so many things I love about this serum & her products in general! ... First let me state, it is clear & liquid, like a water consistency! Do not be put off by this! This is a good thing. You just add one dropper's amount into the palm of your hand (using clean hands) and with both hands pat it onto all of your face. (Clean face)... It absorbs really easy & quick! Feels very light, as if nothing is there. Not sticky or thick! Which is why it being like "water" is a GOOD THING! Because after this serum, you want to be able to apply moisturizer, sunscreen, and/or makeup - without difficulty! It wont ruin or clash with the products you go in with afterwards! I have EXTREMELY sensitive skin! I have to take allergy medicine daily to avoid hives. I have Psoriasis on my elbows & my hairline on the back of my neck. Certain products can make my skin turn red with a burning sensation... Other than certain actual Perfumes, I can not handle fragrance in any of my skincare/hygiene products... It's just, yeah, like I said EXTREME - how sensitive my skin can be. HOWEVER!!! This stuff does not hurt my skin! My face handles some of the Paula's Choice products I've tried so far, really well! I love that it targets my skin's issues, without any irritation (if used properly) ... I know not everyone's skin is the same, but my sensitive skin handles this particular serum just fine, without any problems! I also want to compare this product to another expensive brand I've tried, "La Roche-Posay"... When they were shipped to me, along with Paula's Choice products at the same time, La Roche-Posay's serums came with damaged product boxes & no seal! Their serums are not cheap! So you'd think they could package their stuff better & seal them! It also made me question if they were used, rather than new... On top of that, I did not realize until after they all arrived, that La Roche-Posay's serums all have unnecessary fragrance in them! Not Cool! It made my skin flare up & my skin was irritated as a result! That's when I realized the crap like fragrance... So I stopped using their stuff & continued forth with just my paula's choice & first aid beauty products only! The Paula's Choice products I bought were all packaged well, no damage, & it was clear they were all new! And they have no fragrance! So I will never buy serums from La Roche-Posay again, and just stick with Paula's Choice! Im not gonna waste tons of money on another expensive brand like that, if I can trust THIS ONE more! I also know Paula's Choice products are working, because the results were surprisingly FAST! I have never had a product work so quick before. I was shocked, in a very happy way! I have combination skin. Where some areas are oily & some are dry. With hormonal acne, blackheads on my nose & chin, acne scars on my cheeks & forehead, & visible pores... Or at least I did, prior to this stuff! It made my skin feel evenly soft! Moisture in the dry areas, yet not oily! It evened-out my skin, it feels like. My blackheads & pores & acne are all clearing up & way less visible... Just WOW! Left me speechless, honestly! I expected to go through that adjustment phase, where you breakout until your skin gets used to it. But no, I guess I got lucky, because it just immediately started working. I can't wait to see how clear everything is, with more time & more use! I want to note that I use First Aid Beauty's face wash as a cleanser, First Aid Beauty's Retinol under-eye cream at night, and First Aid Beauty's face ultra moisturizer... HOWEVER, other than that, I am using Paula's choice products (This serum specifically! That dark grey bottle of "Skin Perfecting 2% BHA Liquid Salicylic Acid Exfoliant"... and the light blue bottle of her "Resist Weightless Advanced Repairing Toner, Niacinamide & Hyaluronic Acid") and when my First Aid Beauty's moisturizer is gone, I plan to give Paula's Choice brand of moisturizer a try, to see how it works too! I have fallen in-love with this brand, which I do not say lightly; and because of how well it works for me so far, I feel like I will become a new loyal/regular costumer! The reason I mention what brands I am using together, is to help express what all was used to achieve my awesome results! I do use SPF 30 moisturizer in the La Roche-Posay brand (if Im gonna go outside or be out of the house) but it is unscented, and that was why I originally thought I could trust their serums, until that epically failed for me, because their brand of serums are fragranced & caused my skin to react badly! So kudos to Paula's Choice for NOT being fragranced lol! My sensitive skin thanks you!

My skin looks so much better

I’ve used Paula’s Choice products before and generally trust the brand, but unfortunately this item arrived with visible brown residue around the bottle opening upon first opening. It did not look like normal product leakage or fresh overflow. Given that this is a facial skincare product, I didn’t feel comfortable using it due to possible contamination or oxidation. I requested a return immediately. This may be a storage or handling issue rather than a formula problem, but quality control for sealed products is very important. I recommend checking the bottle carefully upon arrival.
