PCA Skin Vitamin B3 Brightening Serum - 1 oz / 29.5 ml

Brighter, More Even Skin Starts with Vitamin B3

If uneven skin tone, dullness, and discoloration have been standing between you and your best complexion, the PCA Skin Vitamin B3 Brightening Serum is the targeted solution your routine has been missing. Formulated around niacinamide — one of the most clinically validated brightening ingredients in modern skincare — this lightweight serum works to visibly reduce the appearance of dark spots, hyperpigmentation, and uneven tone while simultaneously strengthening the skin barrier and minimizing the look of pores. The result is skin that looks clearer, smoother, and genuinely more radiant with every use.

Niacinamide-Powered, Clinically Proven

PCA Skin is a brand built on clinical science, and the Vitamin B3 Brightening Serum is no exception. Niacinamide (Vitamin B3) works by interrupting the transfer of melanin to the skin's surface, helping to fade existing discoloration and prevent new spots from forming. It also delivers meaningful anti-aging benefits — improving skin elasticity, reducing the appearance of fine lines, and supporting a healthy, balanced complexion. Suitable for all skin types, including sensitive and acne-prone skin, and pairs beautifully with SPF for a complete brightening regimen.

Precision Brightening in a Travel-Friendly Size

The 1 oz / 29.5 ml bottle is perfectly sized for daily use and easy to take on the go. Apply a few drops to cleansed skin morning and evening before moisturizer, and let the niacinamide work its magic. With fast US shipping, this physician-developed brightening essential arrives quickly so you can start seeing results without delay.
