Dermalogica Biolumin-C Serum facial brightening serum 0.34 fl oz — stabilized vitamin C & lactic acid for radiance and lightweight

Dermalogica Biolumin-C Serum is a lightweight, vitamin C–powered facial serum designed to brighten skin, improve firmness, and deliver weightless hydration.

This concentrated 0.34 fl oz serum combines stabilized vitamin C technology with gentle exfoliation and antioxidant-rich plant extracts to boost radiance without heaviness. It layers easily under moisturizers and makeup, making it practical for daily use. The formula targets uneven tone and dullness while supporting skin’s surface texture for a fresher, more luminous appearance.

How does this serum brighten and clarify skin?

The product uses a stable form of vitamin C alongside lactic acid to brighten the complexion and promote smoother skin. Vitamin C helps address visible dullness while lactic acid softly exfoliates dead skin cells, revealing fresher layers without harsh irritation. Antioxidant botanicals further protect from environmental stressors that can make skin look tired.

• Stabilized vitamin C derivative to enhance surface radiance
• Lactic acid for gentle chemical exfoliation and smoother texture
• Sophora japonica flower extract to calm oxidative stress

What are the key ingredients and what do they do?

Formulation highlights include palmitoyl tripeptide-5, lactic acid, chia seed oil, and Sophora japonica extract. Peptides assist with skin firmness, while chia seed oil supplies lightweight hydration and helps maintain skin elasticity. The blend balances brightening and soothing actives for everyday use.

• Palmitoyl tripeptide-5: supports visible firmness
• Lactic acid: resurfaces to reduce the look of fine lines
• Chia seed oil: provides lightweight, non-greasy hydration
• Sophora japonica extract: antioxidant protection to help skin appear calmer

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

Apply a few drops to cleansed skin each morning and evening before moisturizing. It’s designed to be used under creams or sunscreens; in the morning always follow with SPF. Consistent, daily application helps maintain visible brightness and smoother-feeling skin over time.

• Use on clean, dry face and neck—press in gently
• Follow with moisturizer then SPF in daytime routines
• Suitable for layering under makeup without pilling

Is this serum suitable for sensitive or combination skin?

The formulation balances effective brightening with gentle exfoliation, making it approachable for many skin types, including combination skin. Individuals with reactive or very sensitive skin should introduce it gradually and patch-test to confirm tolerance. If irritation occurs, reduce frequency or consult a skincare professional.

• Introduced gradually for sensitive skin to assess tolerance
• Non-greasy texture works well for combination skin types
• Avoid use with strong retinoids unless directed by a professional

Who this is for: Dermalogica Biolumin-C Serum is made for anyone looking to lift dullness and improve skin luminosity without heavy oils—ideal for those who prefer lightweight texture, want visible radiance from a small but potent bottle, and who maintain morning and evening skin routines. It fits into both targeted brightening regimens and everyday skincare for people seeking fresher-looking skin.
