PCA Skin Vitamin B3 Brightening Serum Niacinamide Superstar!

PCA Vitamin B3 Brightening Serum is a Niacinamide-rich advanced brightening serum that reduces the appearance of dark spots, sun damage, and uneven skin tone while improving the skin’s barrier function. This lightweight powerful skin-brightening serum also helps reduce redness, and skin yellowing and promotes a more even skin tone as well as a clear complexion.

The ingredients in the best-selling Vitamin B3 Brightening Serum tackle existing sun damage, help fade spots and help prevent further spots by inhibiting melanogenesis which is the processing by which pigment is created. Customers that use this product report that their skin got brighter, more even, and their complexion more clear.

PCA Vitamin B3 Brightening Serum Features & Benefits:

  • Calms redness and helps minimize skin yellowing
  • Brightens dark spots and evens skin tone by inhibiting melanogenesis
  • Blocks the glycation process to minimize age-related skin yellowing and dullness
  • Boosts and strengthens skin’s barrier function
  • Helps improve skin tone

Featured Ingredients:

  • Niacinamide (Vitamin B3 – 6%) – Calming antioxidant that delivers multiple important benefits to the skin. It helps to reduce transepidermal water loss (TEWL) and improve barrier function. This is critical for healthy, bright skin. Additionally, it helps reduce redness, skin yellowing, and promotes an even skin tone.
  • Mulberry Extract, Green Tea Extract, and Oligopeptide-51 – An advanced ingredient blend that decreases the production of unwanted pigment to brighten skin and produce a clear, even complexion.
  • Plankton Extract – An advanced ingredient derived from a biotechnologically balanced and standardized pool of microalgae actives that have been carefully selected and encapsulated in liposomes. It brightens and evens skin tone while dramatically reducing dark spots and discoloration.
  • Glycerin – A humectant and emollient that helps hydrate the skin.
