We’re still tracking retailers for this one. In the meantime:
The pigmentation-targeted variant of Biologique Recherche's iconic P50 — formulated specifically for skin with melasma, post-inflammatory hyperpigmentation, or chronic photodamage. The 'W' in P50W stands for 'whitening' (the brand's term for pigmentation control, not skin-tone lightening). The formulation drops the original P50's salicylic acid to reduce inflammation pathways that drive melanogenesis, then layers in higher concentrations of niacinamide and phytic acid (a mineral chelator that interrupts melanin synthesis). The vinegar base remains, the multi-acid framework remains, and the daily application protocol — applied 1-2x daily on a cotton pad after cleansing — is the same. Used in BR's authorised institutes as the foundation toner of pigmentation-protocol routines. At $80 for 150ml, premium pricing — and one of the few multi-acid pigmentation toners with this depth of formulation.
