Biologique Recherche Sérum Spectral

Sérum Spectral makes skin visibly more radiant, more even in tone, and measurably more resilient to the light it meets all day. Sun through the window, screens past midnight, the low glow of a room that's never fully dark.

Rooted in photobiology, the science of how skin reacts to light. Serum Spectral takes a different position from everything else on your shelf. It doesn't block light; it strengthens your skin's own ability to live with it.

Three actives do the work. Lingonberry, an Arctic antioxidant that neutralized 100% of UV-induced oxidation in testing. Schisandra berry, which helps clear tired, damaged cells and Indirubin, which sharpens melanin's role as the skin's built-in defense for visibly more radiant skin at four weeks and more even, resilient skin by eight, all in a milky pink texture that disappears on contact.

This is not a sunscreen. Think of it as the layer working behind your SPF. Protection handles the rays, Spectral trains the skin beneath.

• Dull skin lacking radiance and luminosity
• Uneven skin tone and loss of homogeneity
• Daily light exposure, both outdoor (UV) and indoor (screens, ambient light)
• Strengthening the skin's antioxidant defenses
• Improving overall skin quality and resilience over time
• Sensitive skin and all Skin Instants©

Sérum Spectral is built around three actives chosen to strengthen the skin against light-induced stress:

Lingonberry (Vaccinium Vitis-Idaea) - A powerful antioxidant that helps neutralize free-radical damage, demonstrating a 100% reduction of UV-induced oxidation in ex vivo testing.

Schisandra Berry (Schisandra Chinensis) - Supports the skin's natural ability to clear and renew damaged cells, helping maintain a healthier, more resilient complexion.

Indirubin (Polygonum Tinctorium) - Reinforces melanin's role as the skin's natural defensive barrier against light.

Its milky pink emulsion is formulated for optimal tolerance and comfort, absorbing rapidly into all Skin Instants© without a greasy or tinted finish.

Apply morning and evening, using upward massage strokes across the face, neck, and décolleté. Within a Biologique Recherche routine, apply Sérum Spectral during the treatment phase, after your cleansing milk, and the Lotion P50 selected for your Skin Instant©, after any watery serums, and before your daily moisturizer.

Sérum Spectral works to strengthen the skin's resilience to light, but it is not a sunscreen and does not replace sun protection. Always follow with a daily broad-spectrum SPF. Suitable for year-round use.

At which step of my routine should I apply Serum Spectral?
Apply the serum all year-long, morning and night, after using a cleansing milk and one of the Lotions P50 recommended for your Skin Instant©. Because of its fluid emulsion texture, it should be applied after the most watery serums and before your daily moisturizer.

Who can use Spectral?
Spectral can be the foundation of any routine, whatever your age or Skin Instant. It was formulated for daily use, with a texture suited to all skin types, even sensitive.

How often should I use Spectral to get results?
Spectral serum can be applied all year-long, morning and evening. It delivers benefits within the first month with progressive and measurable improvement in skin quality.

From 28 days, radiance improves by +10%,increasing to +16% at 56 days.* complexion uniformity improves by +18% at 56 days, while softness improves by +8% at 28 days, reaching +16% at 56 days.

*Clinical study conducted on 33 volunteers, women and men (average age: 50), phototypes II to IV, with more than 50% presenting sensitive skin – clinical scoring at 28 and 56 days.

**Clinical study conducted on 33 volunteers, women and men (average age: 50), phototypes II to IV, with more than 50% presenting sensitive skin – self-assessment questionnaire at 28 and 56 days

What makes Spectral unique?
Inspired by photobiology, Spectral stands out by being centered on skin resilience. Its objective is to strengthen the skin’s intrinsic capacity to adapt and recover after daily light exposures. It does not target radiation itself, but rather the biological mechanisms naturally mobilized in response to photo-inducedstress. By supporting these internal processes, Spectral accompanies the skin as it faces repeated light exposure and helps preserve skin quality overtime.
