VICHY LiftActiv B3 Serum 8% Niacinamide — Lightweight Dark Spot Corrector, Glycolic & Melasyl

Vichy LiftActiv B3 Serum is a lightweight, fast-absorbing face serum combining 8% niacinamide, Melasyl™, glycolic acid and tranexamic acid to visibly reduce dark spots and even skin tone.

Built from 18 years of research, this updated Vichy formula targets pigmentation at multiple stages: it soothes inflammation, reduces melanin overproduction, and helps shed pigmented surface cells for a brighter, more uniform complexion. The non-sticky serum is fragrance-free, dermatologist- and allergy-tested, and formulated to layer easily under moisturizers and makeup for daily use by all skin types.

How quickly will I see improvements in dark spots?

Clinical testing shows visible changes over weeks, with many users noticing gradual lightening and improved evenness within several weeks of consistent use. Results depend on spot depth, sun exposure, and adherence to a routine that includes sunscreen.

• Clinical study: most users showed improvement within a 14-week period.
• Niacinamide (8%) calms inflammation and evens tone over time.
• Glycolic acid and the peeling complex accelerate surface renewal.
• Melasyl™ works to reduce new pigment formation.

Can I use this serum with other actives or sensitive skin products?

The lightweight formula is designed to pair with other skincare steps, but layering should be done thoughtfully with potent actives. Because the serum is fragrance-free and allergy-tested, many people with sensitive skin tolerate it well, though introducing it gradually is recommended.

• Apply a few drops to clean skin morning and evening.
• Wait a moment before adding hydrating creams or SPF in the morning.
• Avoid mixing directly with other strong exfoliants on the same application.
• If you have very reactive skin, patch-test or alternate nights.

Which ingredients make this serum effective against pigmentation?

This formula combines multiple mechanisms to address dark spots: niacinamide soothes and regulates, Melasyl™ reduces melanin production, glycolic acid promotes surface renewal, and tranexamic acid helps neutralize uneven tone. Together they target both existing discoloration and factors that cause new spots.

• 8% Niacinamide — calms skin and improves clarity.
• Melasyl™ — patented ingredient that inhibits melanin overproduction.
• Glycolic acid + multi-layer peeling complex — gentle exfoliation.
• Tranexamic acid and Rainbow Algae — refine tone and reduce pigment transfer.

Who is this for? Vichy LiftActiv B3 Serum is formulated for adults who want to reduce the appearance of brown spots, post-acne marks, or uneven tone while maintaining a gentle daily routine. It suits all skin tones and many sensitive skin types, but anyone using stronger actives or undergoing professional treatments should consult a dermatologist and add sunscreen to daytime use to protect renewed skin. For best results, use consistently morning and night as part of a complete regimen that includes broad-spectrum sun protection.
