Dermalogica Biolumin‑C Vitamin C Dark Spot Serum, 1 fl oz — Brightening, Peptide & Gentle Exfoliant

Dermalogica Biolumin-C Serum is a potent vitamin C facial serum formulated to brighten skin tone, support firmness, and help reduce the visible signs of aging.

This lightweight, fast-absorbing serum combines stabilized vitamin C with gentle exfoliation and peptides to improve clarity and texture without heavy oils. Designed for daily use after cleansing, it targets uneven tone and the look of fine lines while providing antioxidant support to help skin appear more radiant and resilient.

How does this serum brighten dark spots and uneven tone?

The formula uses a vitamin C derivative that helps even out discoloration over time while minimizing irritation. Exfoliating lactic acid encourages gentle turnover so dull surface cells are sloughed away and fresher skin is revealed.

• Vitamin C technology works to reduce the appearance of dark spots and uneven pigmentation
• Lactic acid provides mild chemical exfoliation to smooth texture
• Consistency of use improves overall luminosity and clarity

Will it help improve firmness and visible fine lines?

Palmitoyl Tripeptide-5 supports skin’s visible firmness by encouraging the look of structural resilience. When combined with antioxidant protection, the serum helps skin appear firmer and the visibility of fine lines is reduced over continued use.

• Peptide blend supports the appearance of firmer skin
• Antioxidant botanicals protect against daily environmental stressors
• Lightweight texture layers easily under moisturizers and SPF

How should I include this serum in my routine and what results can I expect?

Apply a few drops to freshly cleansed skin each morning and/or evening before your moisturizer. Expect gradual improvements in brightness, smoother texture from mild exfoliation, and a more even-looking complexion with consistent use.

• Use 2–3 drops on face and neck after cleansing
• Follow with moisturizer and daily sunscreen in the morning
• Visible improvements typically appear with regular application over weeks

Is the formula gentle enough for sensitive or reactive skin?

The serum balances active brightening and exfoliating ingredients with botanical extracts chosen to calm oxidative stress. If your skin is highly reactive, introduce the product gradually and patch-test first to monitor tolerance.

• Sophora japonica flower extract helps soothe and defend against oxidative stress
• Lactic acid is present at a mild level for gentle exfoliation
• Patch testing and gradual introduction reduce the risk of irritation

Who this is for: Dermalogica Biolumin-C Serum suits anyone seeking a concentrated vitamin C treatment to address dullness, uneven tone, and the early appearance of lines while also supporting skin strength. It's appropriate for skin types that tolerate active ingredients—those wanting a brighter, smoother, more even complexion and who will pair it with a daily SPF for optimal results.
