Product details
A closer look.
Biologique Recherche Sérum Spectral is a daily skin-quality serum inspired by photobiology, the science of how living organisms respond to light. Designed for skin exposed to light every day, indoors and outdoors, it helps skin look more resilient while improving radiance, softness and the appearance of an uneven complexion. Its formula combines antioxidant and botanical ingredients, with Lingonberry Fruit Extract, Schisandra Fruit Extract and Polygonum Tinctorium (a botanical source associated with indirubin) at its centre. Its antioxidant ingredients help protect skin from environmental stressors. Sérum Spectral is not a sunscreen and does not provide sun protection: SPF helps protect the skin from UV radiation, while Sérum Spectral helps skin look more radiant, even and resilient. One does not replace the other, so wear it with your daily SPF. With consistent use, skin appears brighter, smoother, more even and more resilient.
Why you’ll love it.
Sérum Spectral makes the most sense when your goal is not to target one specific concern, but to preserve overall skin quality. We especially like it for clients who say their skin looks tired, their complexion isn't as even as it used to be, or who already use SPF and wonder what else they should be doing. We see SPF and Sérum Spectral as complementary, never interchangeable.

Your questions, answered.
What does photo-resilience mean?
It is the concept behind Sérum Spectral: helping skin that is exposed to light every day look more radiant, even and resilient. It is a skincare concept inspired by photobiology, not a form of sun protection.
Does Sérum Spectral replace sunscreen?
No. It is not an SPF and does not replace sunscreen. Apply sunscreen every morning as the final step of your routine.
Who should use it?
Biologique Recherche recommends it for Skin Instants lacking radiance. It may also suit clients concerned with uneven-looking tone, reduced skin quality or keeping skin looking resilient over time.
Can sensitive skin use it?
It was formulated for all skin types, including sensitive Skin Instants. If your skin is highly reactive or you are unsure, speak with one of our estheticians before introducing it. The formula lists aromatic compounds such as cinnamal and citral, so check the full ingredient list if you are sensitive to them.
Can I use it every day?
Yes. It is designed for year-round use, morning and evening.
When should I apply it?
After cleansing, Lotion P50 and your more watery serums, but before moisturizer. Always finish your morning routine with sunscreen.
Skin Reaction Policy
In the event of a reaction, Biologique Recherche requires photos of the reaction and the product, the lot number found on the product or the bottom of the box, and proof of a consultation with one of our estheticians before they can review the concern.
If you choose to purchase without a consultation and experience a reaction, we will be unable to provide a refund. Our team is always happy to answer your questions and help you select the products best suited to your skin.
