Biologique Recherche Finishing Serums

These serums provide the finishing touch on the BIOLOGIQUE RECHERCHE face care regimen. They should be applied on top of your creme for maximum glow and radiance. 

These precious fluids contain botanical extracts with a variety of vitamins and antioxidants, as well as hyaluronic acid and potent moisturizing and oxygenating DNA extracts. Finishing Serums are a category unique to Biologique Recherche, and are meant to provide an extra layer of protection from environmental stressors. Combined with SPF, you will have a shield from the effects of sun, pollution and free radicals. 

They make an excellent base for makeup, and are perfect for use on both a daily basis and for special events. Finishing serums not only protect your skin from environmental invaders, but they prolong and protect the effects of the BIOLOGIQUE RECHERCHE skin care products.

Frequently asked questions

  • What is a finishing serum?

    A finishing serum is the last step of your Biologique Recherche routine. Apply it after cleansing, Lotion P50, your serums and your crème. In the morning, follow with SPF.

  • Do I still need SPF if I use a finishing serum?

    Yes. A finishing serum is not a sunscreen. Used together with a broad-spectrum SPF, it helps shield your skin from the effects of sun, pollution and free radicals.

  • Can I wear a finishing serum under makeup?

    Yes. Finishing serums make an excellent base for makeup, so they work beautifully for everyday wear and for special events.

  • Which finishing serum is right for me?

    Each finishing serum is designed for different skin needs. If signs of aging are your main concern, Serum Yall O2 and Le Grand Serum are great places to start; see our Finishing Serums for Aging Skin. Book a complimentary skin consultation and we'll help you find the best match for your skin.

  • Do I need a finishing serum if I already use a crème?

    It's optional, but a valuable addition. Your crème nourishes and comforts your skin, while a finishing serum adds a protective layer on top and helps the rest of your routine work longer.

  • How do I apply a finishing serum?

    After your crème has absorbed, apply a few drops to your face and neck and gently smooth it over the skin. Let it settle for a moment before applying SPF or makeup.

  • Should I use a finishing serum in the morning or evening?

    Most clients use their finishing serum in the morning, since its main role is protecting your skin from the day's environmental stressors. Some can also be used in the evening, so ask our estheticians what works best for your routine.

  • How should I store my finishing serum?

    Keep your serum in a cool, dry place away from direct sunlight and heat, and close the cap tightly after each use. Refrigeration isn't required. Once opened, most Biologique Recherche products should be used within 3 to 12 months, depending on the product. Check the open-jar symbol on the packaging for the exact timeframe.
