Rough and bumpy textures meet their match with the TIRTIR PHA 15% Serum, a high-concentration exfoliating treatment designed for those who find traditional acids too harsh. That formula utilizes a 15% concentration of Polyhydroxy Acids (PHA) alongside LHA to lift away dead skin cells while simultaneously drawing moisture into the surface. Unlike gritty scrubs, this liquid solution works to clear congestion and flaky patches without causing the redness or peeling often associated with chemical peels. A unique 1:9 oil-to-water ratio ensures the skin stays hydrated during the exfoliation process, while plant-based phyto-mucin strengthens the natural barrier against environmental stressors. This lightweight, non-sticky serum absorbs quickly to leave the complexion feeling soft, balanced, and noticeably more radiant. Why You Will Love It: Non-Irritating Skin Polishing: Utilises 15% PHA and LHA to gently dissolve surface debris without stripping the skin of its natural oils. Deep Moisture Retention: Features a 1:9 oil-to-water balance that provides an immediate hydration boost to prevent post-exfoliation dryness. Resilience Boosting Mucin: Employs plant-based phyto-mucin to reinforce the skin barrier and protect against external irritants. Fast Absorbing Texture: Boasts a refreshing non-sticky formula that sits comfortably under other skincare products or makeup. How to Use: Apply a few drops to a clean, dry face after toning, avoiding the eye and lip areas. Pat the serum gently into the skin until fully absorbed before following with your favourite moisturiser.
