Paula's Choice 10% Niacinamide Booster (Discontinued)
The Paula’s Choice 10% Niacinamide Booster is a concentrated serum designed to target enlarged pores, uneven skin tone, and fine lines. Formulated with a high concentration of Niacinamide (Vitamin B3), it works synergistically with Acetyl Glucosamine to brighten the complexion and strengthen the skin’s natural barrier. This booster also features Ascorbyl Glucoside, a stable form of Vitamin C, providing antioxidant protection and enhancing radiance. Although this specific version has been discontinued, it remains a benchmark for its lightweight, water-like texture that can be used alone or mixed into other skincare products. The inclusion of Butylene Glycol ensures a smooth, hydrating application without leaving a heavy or greasy residue. For those with acne-prone or congested skin, this formula was celebrated for its ability to refine skin texture and reduce the appearance of post-blemish marks. Its oil-free and fragrance-free profile makes it a versatile addition to any routine focused on clarity and smoothness.
Our Analysis
Our ingredient analysis of the Paula’s Choice 10% Niacinamide Booster reveals a formula with a low comedogenic risk. After scanning the full ingredient list, we found zero flagged components known to clog pores or trigger acne flare-ups. The primary base consists of water and humectants like Butylene Glycol, which are generally safe for all skin types. Because the formulation is free from heavy waxes, oils, and pore-clogging esters, it is an excellent choice for individuals prone to congestion. It effectively delivers active ingredients without the common risks of pore blockage.
Skin Type Recommendations
This booster is ideal for oily, combination, and acne-prone skin due to its lightweight, non-clogging formula. Those with sensitive skin may benefit from Niacinamide's barrier-repairing properties, though the 10% concentration is potent. It is safe for dry skin but is best used when layered under a more occlusive moisturizer.
