I started with the 10% booster to try and minimise the look of my pores. Didn't see much result after several months so decided to try the 20% booster when it came out. I don't think it's done much for the look my pores, but I do feel like it's made my skin tone look more even and glowing. I understand it's a good product for the skin barrier so I decided to keep using it. Would buy again.I used it twice and both times it causes cystic breakouts. First time, I wasn't sure if it was from this product so I stopped using and the break stopped. I used it again after 2 months and got the same results. I haven't changed anything else in my skincare routine and am sure that this product caused the breakoutI’ve been using the Nicacinamide 10% for about 3 years and love love love it. I was so excited to try the new 20% and I haven’t been disappointed. The texture is more oily than the 10% which makes it easier to apply and manipulate. Due to the oily textureI feel this is a better night treatment and the 10% is better for daytime. I recommend Paula’s choice to everyone I know and this product will be going on the list of must have’s.One of the ingredients in the Clinical Niacinamide 20%, purslane, works beautifully for me and it's not easy finding it in a well-formulated product. I've been eager for Paula's new Clinical treatment to become available in the UK. It's exceeded my expectations. I've combined a couple drops of the 20% Niacinamide with one pump of CLINICAL 0.3% Retinol + 2% Bakuchiol Treatment after cleansing and toning at night and the results are lovely. My skin is clear and smooth. It works well with other products. -

Faq
Why did Paula's Choice formulate another niacinamide product?
The Clinical Niacinamide 20% Treatment was the brainchild of Paula herself. Having experienced such great results with the 10% Niacinamide Booster, she wanted to see if doubling the percentage would give her even better results on her most stubborn concerns (clogged pores and sebaceous hyperplasia). The results exceeded expectations and the rest is history. Along with niacinamide, Paula and team added some key supporting ingredients that really make this product a standout for anyone wanting to tackle large pores, rough bumpy texture and uneven skin tone.
How is the Clinical Niacinamide 20% Treatment different from the 10% Niacinamide Booster?
Most notably, it contains twice the amount of niacinamide and is delivered in a gel texture vs. a liquid. Additionally, it includes a variety of supporting ingredients such as meadowsweet, purslane and camellia japonica to help reduce excess oil and offset collagen-degrading enzymes that can lead to stubborn, enlarged pores.
Should customers use the 10% Niacinamide Booster, the Clinical Niacinamide 20% Treatment or both?
It depends on the severity of their primary concerns. If they have more advanced concerns such as stretched, sagging pores, orange peel-like texture, or stubborn oil-related bumps, the 20% strength is a great option. If their concerns are mostly around enlarged pores and uneven skin tone, the 10% strength will meet their needs. Customers can also alternate the two at a cadence that works best for them (this may take some experimenting).
Why is the 20% Niacinamide a part of the Clinical line vs. Boosters?
Clinical is all about advanced solutions which makes it the perfect collection for this new, potent treatment. As an intensive results-oriented product, the Clinical Niacinamide 20% Treatment was specifically formulated to tackle complex skincare concerns for those who find the 10% Niacinamide Booster isn’t quite enough. All Clinical products are formulated to mix into a multitude of routines, giving customers just the right dose they need to target their specific concerns.
