Dermalogica Biolumin-C Serum 0.34 fl oz — Brightening Vitamin C Gel-Serum, Lightweight Hydration

Dermalogica Biolumin-C Serum is a lightweight, vitamin C–powered serum that brightens, hydrates and helps refine skin texture for a radiant, healthy-looking complexion.

This concentrated 0.34 fl oz formula combines advanced vitamin C technology with supportive actives to target dullness and uneven tone while delivering weightless hydration. The fast-absorbing gel-serum layers easily under moisturizer and sunscreen, making it practical for daily use in morning or evening routines. Formulated with Palmitoyl Tripeptide-5 to support a firmer appearance, Lactic Acid for gentle resurfacing, Sophora Japonica Flower Extract to calm oxidative stress, and Chia Seed Oil for lightweight nourishment, the Biolumin-C Serum aims to enhance luminosity without heaviness.

How quickly can I expect to see brighter skin?

Visible improvements vary by individual and routine consistency, but many users notice an overall radiance boost within a few weeks when used daily. Lactic Acid gently accelerates surface renewal while vitamin C technology helps even tone and reflect light, so effects accumulate with regular application.

• Apply morning and/or night to clean skin for best results.
• Lactic Acid promotes subtle exfoliation for smoother texture.
• Use with sunscreen during daytime to protect improved tone.

Will this serum hydrate without feeling greasy?

The Biolumin-C Serum is designed as a lightweight gel that absorbs quickly and layers well beneath creams or sunscreens. Chia Seed Oil provides penetrating moisture and a soft finish, while the formula avoids heavy emollients, so it suits those who prefer non-greasy products.

• Gel-serum consistency for fast absorption.
• Chia Seed Oil offers hydration without weight.
• Works under moisturizers and makeup without pilling.

Is this safe for sensitive or reactive skin?

The serum contains Lactic Acid, an alpha hydroxy acid that gently exfoliates; some sensitive or easily reactive skin types may prefer to patch-test first. Sophora Japonica Flower Extract is included to help soothe oxidative stress, but if you have a history of sensitivity to acids or vitamin C, start slowly and monitor your skin's response.

• Patch-test on inner wrist or jawline before full use.
• Introduce gradually—every other day—if concerned about irritation.
• Discontinue if persistent redness or discomfort occurs.

How should I incorporate this into my skincare routine?

Use the Biolumin-C Serum after cleansing and toning, before moisturizer and sunscreen. A few drops are enough to cover the face and neck; gently press the product in rather than rubbing to ensure even absorption.

• Cleanse, then apply 2–3 drops of serum to face and neck.
• Follow with moisturizer and broad-spectrum SPF in the morning.
• Can be used alone at night or paired with other targeted treatments.

Who is this for: Dermalogica Biolumin-C Serum is suited to anyone seeking a lightweight brightening serum that balances gentle resurfacing and hydration. It appeals to those wanting to reduce dullness and refine texture without heavy creams—ideal for normal, combination, and oilier skin types, and for anyone layering antioxidants into a daily skincare regimen. If you have highly sensitive or medically reactive skin, consult a dermatologist or perform a patch test before integrating this serum into your routine.
