Niacinamide Skincare

Niacinamide or Vitamin B3 is a proven skincare ingredient that targets dark spots, evens skin tone, minimises pores, and strengthens the skin moisture barrier. It works best paired with complementary actives like Retinol or Melasyl for accelerated pigmentation correction. Vichy's niacinamide serums and moisturisers deliver visible results in tone and clarity, with formulas gentle enough for sensitive skin. Dermatologist-tested and hypoallergenic.

Frequently Asked Questions
NIACINAMIDE

What does niacinamide do for the skin?

Niacinamide (Vitamin B3) inhibits the transfer of melanin to skin cells, visibly reducing dark spots and hyperpigmentation over time. It also strengthens the skin barrier, reduces redness, minimises the appearance of pores, and regulates sebum production — making it effective for a wide range of skin concerns.

How long does niacinamide take to work on dark spots?

Most people begin to see visible improvement in dark spots and skin tone within 4–8 weeks of consistent use. Vichy's Pigment Specialist B3 Serum, which combines Niacinamide with the exclusive Melasyl molecule, is clinically proven to reduce dark spots by up to 86% in 3 months.

Can I use niacinamide with retinol?

Yes — niacinamide and retinol are one of skincare's most effective pairings. Niacinamide helps buffer retinol's potential irritation while adding complementary tone-correcting and barrier-strengthening benefits. Vichy's B3 Tone Correcting Retinol Night Cream combines both actives in one formula.

Is niacinamide suitable for sensitive skin?

Yes. Niacinamide is one of the most well-tolerated active ingredients available and is generally suitable for all skin types including sensitive and reactive skin. All Vichy niacinamide formulas are hypoallergenic and tested under dermatological control.
