Dermalogica Biolumin-C Serum is a concentrated vitamin C treatment that brightens, firms, and helps reduce the appearance of dark spots and fine lines.

This lightweight serum combines advanced Vitamin C technology with targeted peptides and gentle exfoliants to improve skin tone and texture. Formulated to support skin’s natural defenses, the 2 fl oz bottle is designed for daily use under moisturizer and sunscreen. It layers easily into morning or evening routines and is suitable for anyone looking to address dullness, uneven tone, and the early signs of aging without heavy oils or sticky residues.

How does this serum brighten skin and target dark spots?

The formula uses stabilized Vitamin C to help even skin tone and diminish the look of dark spots over time. Complementary antioxidants help neutralize environmental stressors that can accelerate dullness and pigmentation, while regular use reveals a more luminous complexion.

• Stabilized Vitamin C concentrates for targeted brightening.
• Sophora Japonica Flower Extract to calm oxidative stress.
• Daily application reduces the appearance of uneven tone.

Will this product improve firmness and reduce fine lines?

Yes — peptides and Vitamin C work together to support skin’s firmness and help smooth the appearance of fine lines. Palmitoyl Tripeptide-5 signals structural support while hydrating botanicals maintain suppleness for a visibly firmer look.

• Palmitoyl Tripeptide-5 to support resilience and texture.
• Hydrating Chia Seed Oil helps plump and soften fine lines.
• Consistent use contributes to smoother-looking skin.

How does the serum exfoliate without irritation?

The serum includes lactic acid, a gentle alpha hydroxy acid, to promote surface cell turnover and refine texture without over-stripping. Paired with calming botanicals, the exfoliation is balanced to reduce the risk of irritation when used as directed.

• Lactic Acid for mild, effective exfoliation.
• Sophora Japonica to soothe and reduce oxidative discomfort.
• Suitable for gradual incorporation into routine to monitor tolerance.

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

Apply a few drops to cleansed skin before moisturizing, both morning and evening as tolerated. In the morning follow with broad-spectrum sunscreen to protect results and prevent new discoloration, and at night pair with a gentle moisturizer for recovery.

• Use 2–4 drops on cleansed face and neck.
• Layer under moisturizer; wear sunscreen during daytime use.
• Introduce gradually if you have sensitive skin.

Who is this for: Dermalogica Biolumin-C Serum is intended for people wanting to brighten dull skin, even tone, and support firmness—ideal for those noticing early signs of aging or uneven pigmentation. It’s formulated for most skin types; anyone with sensitive or reactive skin should patch test and introduce the serum slowly. The 2 fl oz size suits daily use and provides enough product to evaluate visible improvements in texture and tone when incorporated consistently into a skincare regimen.
