Paula's Choice BOOST C15 Super Booster is a concentrated vitamin C serum formulated with 15% pure ascorbic acid, vitamin E, and ferulic acid. This combination is designed to help brighten the skin tone, reduce the appearance of discoloration, and support a more even complexion. The addition of vitamin E and ferulic acid is intended to enhance the stability and effectiveness of the vitamin C, while also providing antioxidant protection against environmental stressors.

This serum has a lightweight, water-like texture that absorbs quickly without leaving a greasy or sticky residue. It is fragrance-free, making it suitable for those who prefer products without added scent. The formula is gentle enough for most skin types, including sensitive and oily skin, though individuals with very sensitive skin may wish to patch-test first due to the active level of vitamin C.

The product is packaged in an opaque, air-restrictive bottle to help preserve the potency of the vitamin C. It can be used as part of a daily skincare routine, typically applied after cleansing and before moisturizer. It is designed to layer well under sunscreen or makeup.

Key aspects of this booster include a focus on a well-researched antioxidant blend, a stable formulation, and a non-irritating base that avoids common irritants such as fragrance, alcohol, and essential oils. The serum aims to support a brighter, more radiant complexion over time when used consistently. It is particularly suited for those looking to address uneven skin tone, dullness, or early signs of sun damage.
