Authorized PCA Skin Retailer — Sourced directly from PCA Skin, guaranteed authentic. Our estheticians reach for this one when clients want to fade dark spots without irritation.

What Makes It Different

Built around 6% niacinamide, this serum reduces dark spots and uneven tone while blocking the glycation process that causes age-related yellowing and dullness. It also strengthens the skin barrier, which means less redness alongside the brightening.

Who It's For

Great for mature or dull-looking skin dealing with dark spots, uneven tone, or persistent redness.

How to Use

After cleansing, toning, and any PCA treatment serums, apply to the entire face and neck. Follow with PCA SPF during the day and moisturizer at night.

FAQ

What does Vitamin B3 Brightening Serum actually do? It targets dark spots and uneven tone using 6% niacinamide, while also blocking glycation (a cause of skin yellowing) and strengthening the skin barrier to reduce redness.

Is this the same as a regular niacinamide serum? It's formulated at a clinical 6% concentration plus mulberry extract, green tea extract, and plankton extract for brightening, more targeted than most over-the-counter niacinamide products.

Who should use this serum? Anyone with dark spots, dullness, or uneven tone, especially mature skin that also needs barrier support.
