What are Biologique Recherche Quintessential Serums?

Quintessential Serums are Biologique Recherche's highly concentrated treatment serums. Each one targets a specific skin need, such as hydration, fine lines, firmness, pores or post-breakout marks. They're cold-processed to protect the potency of their active ingredients, and their lightweight texture absorbs quickly without residue, so they layer easily with the rest of your routine.

Where do Quintessential Serums go in my skincare routine?

Apply your quintessential serums after cleansing and Lotion P50, and before your finishing serum or crème. In the morning, finish with SPF.

Can I use more than one Quintessential Serum at a time?

Yes. Quintessential Serums are designed to be combined, so you can address more than one concern at once. A common approach is to pair a hydration serum with one targeted serum. Apply them one after the other, letting each absorb before the next. Our estheticians can help you choose a combination that works well together.

How do I apply a Quintessential Serum?

After Lotion P50, apply a few drops to your face and neck and gently press or smooth it into the skin until absorbed. A little goes a long way with these concentrated formulas.

Do I still need a moisturizer after a Quintessential Serum?

Yes. Quintessential Serums deliver concentrated actives, but they're lightweight and don't replace your crème. Follow with a Biologique Recherche crème to seal in the benefits and support your skin barrier.

Can I use Quintessential Serums if I have sensitive or acne-prone skin?

Yes, there are options for both. For acne-prone skin, Serum Vivant to visibly reduce blemishes and redness, regulate excess sebum, and reinforce the skin barrier, or Serum Complexe Iribiol helps rebalance and purify. For sensitive skin, book a consultation so we can recommend the best approach for your skin.

How long before I see results?

Hydration serums often make skin feel more comfortable right away. Serums for concerns like fine lines, firmness or pigmentation work gradually, with results building over several weeks of consistent daily use.

How do I store my Quintessential Serums?

Keep your serums in a cool, dry place away from direct sunlight and heat, and close the cap tightly after each use. A steamy bathroom or sunny windowsill isn't ideal. Refrigeration isn't required, but some people like keeping serums in the fridge for a cooling effect. 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.
