The Biologique Recherche Lotion P50V is a multi-functional exfoliating and reconditioning toner specifically formulated for devitalised, mature, or weakened skin. Combining exfoliation, purification, and regeneration in a single step, this advanced formula works to accelerate epidermal renewal, rebalance the skin, and restore clarity, tone, and vitality. It delivers both immediate resurfacing effects and long-term improvement in skin strength and function. At the core of the formula is a synergistic exfoliating complex composed of Lactic Acid, Salicylic Acid, and Gluconolactone. This blend provides progressive and controlled exfoliation—eliminating dead skin cells, unclogging pores, and smoothing uneven texture—while remaining suitable for more fragile skin conditions. By stimulating cellular turnover, it helps reduce dullness, soften fine lines, and visibly refine the skin’s surface. This exfoliating action is reinforced by a regenerating and stimulating complex featuring Walnut Extract and Sponge (Spongilla) Extract. These ingredients promote epidermal renewal by activating micro-circulation and encouraging natural skin regeneration. Their keratolytic and bio-stimulating properties enhance the skin’s renewal cycle, contributing to improved texture, increased vitality, and a more refined, even complexion. A purifying and rebalancing complex centred around Vinegar (Acetic Acid) helps restore the skin’s natural pH while regulating excess sebum. This action tightens the appearance of pores, reduces congestion, and leaves the skin clarified, toned, and balanced. Niacinamide (Vitamin B3) supports barrier function and improves overall skin resilience while helping to regulate oil production and reduce redness. Its brightening properties promote a more even skin tone, while its anti-inflammatory benefits help minimise sensitivity. To ensure skin comfort, a soothing botanical complex including Arnica Extract and Witch Hazel works to calm irritation, support microcirculation, and reduce reactivity. These ingredients help maintain balance within the skin while reinforcing its natural defences. Hydrating agents such as Glycerin provide essential moisture retention, preventing dehydration and supporting barrier integrity. This ensures the skin remains supple, comfortable, and protected despite ongoing exfoliation. Together, these precisely selected actives deliver a comprehensive approach to skin renewal—exfoliating, purifying, and regenerating the skin while strengthening its barrier, refining texture, and restoring radiance for a smoother, clearer, and more revitalised complexion over time.
