Biologique Recherche Serum Spectral

DAILY PHOTO-RESILIENCE SERUM

Biologique Recherche Sérum Spectral is a daily skin-quality serum inspired by photobiology — the science of how living organisms respond to light.

Designed to support the skin through everyday light exposure, Sérum Spectral helps strengthen the skin’s natural resilience while improving radiance, softness and the appearance of an uneven complexion.

Rather than acting as sunscreen, Spectral works within the skincare routine to support the biological mechanisms the skin naturally uses to adapt and recover following daily light exposure.

With consistent use, skin appears brighter, smoother, more even and more resilient.

Skin Instant:

Recommended for Skin Instants lacking radiance or showing uneven tone, reduced softness or signs of daily environmental stress.

Suitable for all skin types, including sensitive skin.

Sérum Spectral is particularly interesting for anyone looking to preserve overall skin quality and support the skin against the effects of repeated daily light exposure.

Benefits:

• Helps strengthen the skin’s natural resilience to daily light exposure
• Provides powerful antioxidant support
• Improves visible radiance and luminosity
• Helps create a more even-looking complexion
• Improves skin softness and overall skin quality
• Supports the skin’s natural adaptive mechanisms
• Suitable for year-round daily use

Clinically Evaluated Results:

With twice-daily application:

• +10% radiance after 28 days
• +16% radiance after 56 days
• +18% improvement in skin tone evenness after 56 days
• +8% improvement in skin softness after 28 days
• +16% improvement in skin softness after 56 days

Biologique Recherche also reports antioxidant activity demonstrating a 100% reduction in UV-induced oxidation levels in an ex vivo study.

Clinical evaluation and VISIA analysis were conducted on 33 volunteers aged 23 to 70, across different skin types, including uneven complexions and excluding melasma.

What Makes Sérum Spectral Different?

Most clients understand sunscreen. Sérum Spectral introduces another conversation: how well the skin itself responds to daily light exposure.

Inspired by photobiology, its formula is designed to support the skin’s intrinsic ability to adapt and recover after repeated exposure to light.

Think of SPF and Sérum Spectral as having two very different jobs.

SPF helps protect the skin from UV radiation.

Sérum Spectral supports the skin mechanisms involved in responding to daily light exposure.

One does not replace the other.

How to Use:

Apply Sérum Spectral morning and evening to the face, neck and décolleté using gentle upward movements.

Within a Biologique Recherche routine:

1. Cleanse the skin
2. Apply the appropriate Lotion P50
3. Apply your most fluid, water-based serums
4. Apply Sérum Spectral
5. Follow with your moisturizer
6. In the morning, always finish with sunscreen

Its fluid-emulsion texture means Sérum Spectral should generally be applied after more aqueous serums and before your cream.

Use throughout the year.

Loshen & Crem’s Recommendation:

Sérum Spectral makes the most sense when your goal is not necessarily to correct one specific concern, but to preserve overall skin quality.

We especially like it for clients who say:

“My skin looks tired.”

“My complexion isn’t as even as it used to be.”

“I want to protect the quality of my skin long term.”

“I already use SPF. What else should I be doing?”

This is where Sérum Spectral becomes interesting.

It is a daily support serum for radiance, evenness and resilience — particularly relevant for skin continuously exposed to light, both indoors and outdoors.

And because Sérum Spectral does not replace sunscreen, we consider the two complementary rather than interchangeable.

The Science Behind Sérum Spectral:

Biologique Recherche highlights three key active ingredients at the centre of the formula:

Lingonberry Extract
A powerful antioxidant-rich botanical that helps support the skin against oxidative stress associated with light exposure.

Schisandra Berry Extract
Supports the skin’s natural processes involved in removing damaged cellular components.

Indirubin
A botanical-derived active that helps reinforce the role of melanin as part of the skin’s natural response to light.

Key Ingredients:

• Vaccinium Vitis-Idaea (Lingonberry) Fruit Extract: Provides antioxidant support and helps preserve skin quality.
• Schisandra Chinensis Fruit Extract: Helps support the skin’s natural renewal and adaptive mechanisms.
• Polygonum Tinctorium Leaf/Stem Extract: Source associated with indirubin, used to support the skin’s natural response mechanisms.
• Moringa Oleifera Seed Oil: Helps nourish, soften and support skin comfort.
• Decarboxy Carnosine HCl: Provides antioxidant support against oxidative stress.
• Saccharide Isomerate: Helps maintain hydration and skin comfort.
