Biologique Recherche’s historic advancements in luxury skincare have produced an expansive selection of highly concentrated and effective serums, thoughtfully designed by experts to treat a variety of common skin concerns.

As to how Biologique Recherche serums work, Purely organic combinations of marine and botanical extracts come together to deliver high-performance, skin-loving formulas; Nourishing, repairing, and protecting with minimal risk of allergic reactions. BR serums are crafted in cold temperatures, which perfectly preserves vitamins, enzymes, genetic material, and antioxidants found in Biologique Recherche formulas.

Whether you're targeting dryness, dullness, fine lines, or sensitivity, BR serums offer a personalized approach to skincare that feels clinical and high-performance, without feeling invasive.

With 25 and counting options to choose from, finding the right product can feel like a challenge, but doing so is simpler than it seems. Nearly all of them fall under 3 different categories: quintessential, targeted, and Finishing.

Biologique Recherche quintessential serums are the most abundant in their range. These water-based formulas are designed especially for dry or aging skin, helping to deeply hydrate while reducing the appearance of fine lines and wrinkles. It comes down to the addition of powerful ingredients like amino acids and peptides to regulate your skin.

Targeted serums are better for combating the effects of short-term conditions like rosacea, hyperpigmentation, and skin inflammation, and finishing serums can help you wrap up your skin regime by stabilizing and reinforcing the products used in your skin regime with antioxidants, vitamins, HA, and DNA extracts.

You should aim to use these serums at least once per day, in either the morning or evening (though both am and pm are often recommended for best results). The standard advice in the Biologique Recherche methodology is to apply these after you have cleansed and toned your face, and before your creams and moisturizers. Finishing serums should always come last, as the name entails, but don’t forget to throw on your favorite sunscreen afterwards.

When applying your serum of choice, massage about 1ml into the entirety of your face, neck, and décolleté, ensuring the product is fully absorbed into the skin with upwards motions. If you prefer, you can do this with up to 3 more serums in the same routine!

The order of serum application should be Quintessential Serums first with the lighter serums followed by the thicker consistency serums. Always go light to thick. Follow with your Targeted Serums and the your final step are the Finishing Serums.

Most users see initial results from BR serums fairly quickly, with hydration, plumping, and surface radiance often noticeable within a few days to one or two weeks. This is the case especially when using hydrating or finishing serums that work at the skin’s surface. Things like smoother texture, rebalanced oil production, improved firmness, and calmer skin require deeper work, and can take between 2 and 4 weeks, depending on how severe or specific your skin condition is. If it’s a targeted serum concern like pigmentation or uneven tone, you may find that results come on the further end of this timeline.

Generally, but some options are better suited for sensitive skin than others. If you’ve found your skin reacts poorly to synthetic ingredients, you won’t need to worry about that with Biologique Recherche, but more active formulas can be too harsh for sensitive skin.

That said, certain products like Serum Biosensible are designed specifically for sensitive skin, restructuring and reconditioning to help you build tougher skin from the ground up. It’s gentle enough to be recommended for any post-surgery recovery, and provides fast relief for reactions. For sensitive skincare that also needs hydration support, consider adding Serum Extraits Tissulaires

This is called layering, and you’re encouraged to implement up to 4 BR serums in your regime if you’d like. Any more might provide a level of active ingredients that becomes overwhelming for your skin barrier, and can trigger less than favorable reactions like redness or irritation. If you’re mixing and matching BR serums as a "Serum Cocktail" it's always a good idea to start with your lighter Biologique Recherche quintessential serums before your targeted serums, saving any finishing serums for last.

The general rule is to apply your thinner or lighter serums first and follow with your thicker more dense serums like Serum Colostrum VG or Serum Collagene Originel.

In short, yes. But the specific serums you choose and how you use them should adapt to the weather and your skin’s changing needs, so you can maximize the benefits while limiting environmental interference. This level of attention isn’t required, but helps if you’re someone who is extra serious about their skincare journey.

In cold, dry climates, serums that offer more hydrative benefits like Colostrum VG can be super beneficial, whereas in hot, humid weather, lighter serums or those focused on oil balance are often more comfortable and effective, like Serum Complexe Iribiol . Given you can use up to 3 in a routine, users living in places that experience both hot and cold weather can effortlessly add and drop their selections based on the season.

Serum Grand Millésime Finsihing Serum is a luxurious finishing serum rich in regenerating and antioxidant ingredients that smooth wrinkles, tone the skin, strengthen natural defenses, and enhance radiance and hydration, often regarded as the best Biologique Recherche serum for aging.

The Serum Fluid VIP O2 Oxygenating Serum is a best seller for it's anti-aging benefits, oxygen cell infusion and protection of the skin barrier.

Serum Complexe Iribiol purifies and regulates your skin’s sebum production, which helps control excess oil, minimizes enlarged pores, and reduces breakouts, making it especially useful for combination, oily or acne-prone skin.

Serum ISO Placenta is a popular choice that features a biomimetic placenta complex to diminish post-acne marks, soothe redness, and refine uneven texture, supporting overall restoration and a smoother complexion.
