Complexe Iribiol by Biologique Recherche is a purifying and rebalancing treatment serum designed to regulate sebum, minimize breakouts, and tighten pores. Ideal for oily, acne-prone, or congested skin, this lightweight formula delivers clarifying actives to help refine texture, calm inflammation, and support a clearer, more balanced complexion.
This targeted serum balances oil production and addresses blemishes without drying or irritating the skin. Complexe Iribiol works at the source of breakouts—reducing excess sebum, calming inflammation, and tightening pores—while helping prevent new imperfections from forming.
This serum is ideal for anyone struggling with persistent breakouts, oily T-zones, or hormonal acne. It delivers fast-acting results without stripping the skin, making it a gentle yet effective option for long-term clarity.
Skin feels clearer, smoother, and more balanced. Breakouts appear reduced and inflammation is calmed. With consistent use, pores tighten, shine diminishes, and skin tone becomes more even and refined.
Complexe Iribiol is a powerful ally in your fight against breakouts and excess oil. Lightweight, targeted, and effective—it restores clarity and confidence without compromising the skin’s natural balance.
