Le Grand Sérum by Biologique Recherche is the brand’s most luxurious and comprehensive serum, designed to rejuvenate, hydrate, and illuminate the skin. With a synergistic blend of over 27 active ingredients, it addresses signs of aging, boosts radiance, and reinforces skin defenses—making it the ultimate all-in-one treatment for a visibly revitalized complexion.
Le Grand Sérum delivers unparalleled results by targeting all major skin concerns—wrinkles, dullness, loss of firmness, dehydration, and oxidative stress. It supports the skin’s natural functions and enhances the efficacy of every product used alongside it. Consider it your skin’s daily reset button.
This is Biologique Recherche’s most advanced serum—crafted for those who demand the highest performance from their skincare. With its featherlight texture and exceptional ingredient profile, Le Grand Sérum delivers immediate radiance and long-term transformation.
Can be used alone or layered with other targeted serums for maximum benefit.
Skin appears more luminous, lifted, and refined. With regular use, fine lines soften, hydration levels increase, and the complexion looks visibly healthier and more youthful. Le Grand Sérum is a luxurious step that leaves skin feeling—and looking—exceptional.
Le Grand Sérum is the ultimate expression of Biologique Recherche’s anti-aging expertise. A high-performance elixir that targets every aspect of skin quality, it transforms your routine and your results—delivering radiance, resilience, and rejuvenation in one timeless formula.
Le Grand Serum is the best finishing serum I've ever used. Even when I try something new I always come back to Le Grand. There's nothing like it for sealing in all that comes before it. The protective barrier it creates saves my sensitive skin from the harsh arid desert environment. Pricey but absolutely worth it!
Le Grand Serum, like all other Biologic Recherge serums, is fantastic. My skin is glowing after this one.
Absolutely love this serum - feels like a coating of protection and sun glow in your skin
