Dermalogica Biolumin-C Serum Vitamin C brightening gel — 0.34 fl oz, lightweight hydration & gentle exfoliation

Dermalogica Biolumin-C Serum is a lightweight daily vitamin C gel-serum that brightens, hydrates, and helps smooth skin texture for a healthy luminous look.

This concentrated 0.34 fl oz bottle combines stabilized vitamin C technology with gentle exfoliation and antioxidant plant extracts to boost radiance without heaviness. Designed for daily use under moisturizer, the formula targets dullness, uneven tone, and early signs of texture change while adding light hydration from chia seed oil. It’s formulated for home skincare routines and to layer easily with sunscreen and other treatments.

How does this serum improve skin brightness and tone?

The serum uses a vitamin C delivery system plus palmitoyl tripeptide-5 to support a clearer, more even-looking complexion. Lactic acid offers mild exfoliation to reveal fresher surface skin while botanical antioxidants defend against oxidative stress. Together they reduce the appearance of dullness and promote a luminous finish without stripping moisture.

• Stabilized vitamin C for visible radiance
• Palmitoyl Tripeptide-5 for firmer-looking texture
• Lactic Acid gently exfoliates to smooth skin
• Sophora Japonica extract provides antioxidant support

What is the right way to use this 0.34 fl oz bottle in my routine?

Apply a few drops to freshly cleansed skin each morning and evening before moisturizer; if using in the morning, follow with broad-spectrum SPF. Because it’s a concentrated formula, a little goes a long way—press or pat the serum into face and neck until absorbed. Layering with compatible actives is possible, but introduce gradually if combining strong exfoliants or retinoids.

• Use 2–3 drops on clean skin, morning and/or night
• Pat into face and neck until fully absorbed
• Follow morning use with sunscreen
• Introduce alongside other actives slowly to monitor tolerance

Which ingredients make this product hydrating yet lightweight?

Chia seed oil supplies light, skin-softening hydration without a greasy finish, while the gel texture allows quick absorption. The formula balances moisturizing elements with exfoliating lactic acid so skin feels hydrated and smooth rather than tight. Humectant and emollient components maintain comfort under makeup and during layering.

• Chia Seed Oil provides lightweight hydration
• Gel delivery for fast absorption and no heavy residue
• Lactic Acid refines texture while retaining moisture
• Formulated to sit well under moisturizer and SPF

Who is this for: Dermalogica Biolumin-C Serum is suited for people seeking a daily brightening boost who want a non-greasy, fast-absorbing vitamin C treatment. It’s a good match for normal, combination, and dry skin types looking to minimize dullness and improve surface texture. If you have sensitive skin, introduce the product gradually and consider patch testing—consult a dermatologist if you use multiple active treatments.

Key features recap:

• Visible radiance from vitamin C technology and Palmitoyl Tripeptide-5
• Mild exfoliation with Lactic Acid for smoother skin
• Antioxidant support from Sophora Japonica Flower Extract
• Hydrating, lightweight feel thanks to Chia Seed Oil
• Small 0.34 fl oz size ideal for travel or introduction to vitamin C

For best results, incorporate the serum consistently into your morning or evening routine, protect skin with SPF during daytime use, and store the bottle upright in a cool, dry place to preserve potency.
