Biologique Recherche Complexe Iribiol is a targeted spot treatment for active acne. It regulates sebum secretion and tightens pores, diminishing acne-causing bacteria and reducing inflammation. Iris Extract is rich in flavonoids, offering strong antimicrobial and anti-inflammatory benefits, while its tannins provide astringent properties that tighten pores and help to regulate sebum over time. Zinc Extract offers potent healing, astringent and antimicrobial properties, helping to regulate hormone-triggered oil production, shrink enlarged pores and reduce the appearance of breakouts. Beta-Hydroxy Acid (Salicylic Acid) penetrates into the pores to exfoliate sebaceous plugs and dead cell debris from within, preventing congestion before it reaches the skin's surface as visible blemishes. Together, these three key actives target the root causes of oily and blemish-prone skin, producing a measurably clearer, less congested and more refined complexion with regular use.
