PCA Skin Vitamin b3 Brightening Serum

This serum is designed to reduce the appearance of dark spots, redness, and uneven skin tone. It uses 6% niacinamide alongside a blend of mulberry extract, green tea, and oligopeptide-51 to inhibit excess melanin production. It also blocks the glycation process that causes age-related yellowing and dullness, while strengthening the skin's barrier function for a healthier, brighter complexion.

PCA Skin Vitamin b3 Brightening Serum is widely regarded as one of the most effective professional-grade niacinamide serums for targeting dark spots. With 6% niacinamide combined with plankton extract encapsulated in liposomes, it addresses pigmentation from multiple pathways — making it a standout choice compared to serums that rely on a single brightening ingredient.

Most users begin to notice visible improvements in skin brightness and tone within 4–8 weeks of consistent daily use. Some users report a brighter, more luminous complexion within the first few weeks, with dark spots continuing to fade with ongoing use. For best results, apply morning and evening as part of a complete skincare routine.

Yes, niacinamide pairs well with most active ingredients. You can layer this serum alongside vitamin C serums for enhanced brightening benefits, or use it in the same routine as retinol products. Apply your treatment serums first, then follow with this brightening serum. If you experience any sensitivity, alternate usage or consult a skincare professional.

Absolutely. This serum is formulated for all skin types including sensitive skin. Niacinamide is known for its calming, anti-inflammatory properties, and this formula is free from fragrance, parabens, and synthetic dyes — all of which can trigger sensitivity. The gentle yet effective formula makes it an excellent choice for those who find other brightening ingredients too harsh.

Yes. Niacinamide at 6% concentration is clinically recognised for its ability to reduce redness and calm inflammation. This serum also strengthens the skin's barrier function, which helps prevent future flare-ups and keeps the complexion looking calm and even. It's an excellent option for those dealing with redness alongside uneven skin tone.

Glycation is a natural process where sugar molecules attach to proteins like collagen, causing the skin to appear yellow, dull, and less supple over time. PCA Skin Vitamin b3 Brightening Serum contains ingredients that block this glycation process, helping to minimise age-related yellowing and restore a brighter, more youthful-looking complexion.

After cleansing and toning, apply any treatment serums (such as vitamin C or retinol) first. Then dispense one pump of the Vitamin b3 Brightening Serum and apply to the entire face and neck. In the morning, follow with a broad-spectrum SPF. In the evening, follow with your moisturiser. This serum sits at the "correct" step of the PCA Skin regimen — between toning and hydrating.

This serum does not contain retinoids, hydroquinone, salicylic acid, or other commonly restricted pregnancy ingredients, and its key active — niacinamide — is generally considered safe for use during pregnancy. However, as with any skincare product, PCA Skin recommends consulting with your healthcare provider or midwife before introducing new products during pregnancy or breastfeeding.
