Dermalogica Biolumin-C Vitamin C Serum — 2 fl oz Brightening, Peptide + AHA Exfoliating Treatment

Dermalogica Biolumin-C Serum is a high-performance vitamin C serum that brightens, firms and exfoliates to reduce the look of dark spots and early signs of aging.

This lightweight, fast-absorbing serum combines a stabilized vitamin C complex with Palmitoyl Tripeptide-5, lactic acid and antioxidant botanicals to support visible skin radiance and texture. Designed for daily use under moisturizer and sunscreen, it targets uneven tone, dullness and the appearance of fine lines while providing hydration and gentle resurfacing. The formula balances active brightening with skin-conditioning ingredients to help maintain a more even, luminous complexion.

How does this serum improve dull, uneven skin tone?

The vitamin C technology in Biolumin-C works to brighten and even skin tone while lactic acid provides mild exfoliation to reveal fresher skin. Together they help reduce the appearance of dark spots and surface discoloration with continued use.

• Stabilized vitamin C complex helps brighten and even skin tone
• Lactic acid gently removes dead skin cells for visible radiance
• Antioxidant botanicals soothe oxidative stress and maintain clarity

Will it help improve firmness and fine lines?

Peptide technology, specifically Palmitoyl Tripeptide-5, supports the look of firmer skin and smoother texture by encouraging skin’s natural resilience. Regular application can make fine lines less noticeable while delivering a lifted, more toned appearance.

• Palmitoyl Tripeptide-5 targets skin firmness and surface smoothness
• Hydrating oils help plump and soften fine lines
• Lightweight serum layer pairs well with moisturizers for added benefit

How should I use Biolumin-C Serum in my skincare routine?

Use the serum on cleansed skin, morning and/or evening, applying a few drops across the face before moisturizers and sunscreen. For daytime, follow with broad-spectrum SPF; for evenings, it pairs well with calming or hydrating treatments.

• Apply on clean, dry skin—few drops are sufficient
• Follow with moisturizer, and always add SPF in the morning
• Introduce gradually if you’re new to acid exfoliants or active serums

What key ingredients deliver results and how do they support skin?

Biolumin-C blends targeted actives with supporting botanicals for multifaceted benefits: brightening, gentle exfoliation, antioxidant defense and hydration. These components work together to improve tone, texture and overall radiance without heavy residue.

• Lactic acid: mild exfoliant to smooth skin surface
• Sophora Japonica Flower Extract: antioxidant protection to calm oxidative stress
• Chia Seed Oil: lightweight hydration that helps maintain barrier comfort
• Palmitoyl Tripeptide-5: peptide that supports visible firmness

Who is this for: Dermalogica Biolumin-C Serum suits anyone seeking a daily brightening and firming treatment—ideal for those noticing early signs of aging, dullness or uneven pigmentation. It’s formulated for normal to dry or combination skin types that can tolerate gentle exfoliation; sensitive skin users should patch-test and introduce the serum slowly. Use as part of a routine that includes sun protection for best visible results.
