The YSL NIGHT REBOOT SERUM is the flagship serum in the Pure Shots range. Its formula is enriched with moonlight cactus flower extract, which blooms for only 6 hours every year and releases its sugar during this rare occasion. The plant's rare sugar has been captured through a cold and slow extraction process designed for YSL Beauty. The bi-phase (exfoliating-in-oil) formulation combines 3.4% Glycolic Acid with Moonlight Cactus flower extract from Morocco. The bi-phase formula consists of an oil phase that meets an exfoliation phase – a combination that both smooths and refines the feel of skin. The formula helps to encourage the removal of dead skin cells while simultaneously hydrating the skin. After the very first use, women perceived the serum’s benefits including: 80% agree skin looks less tired, 79% agree skin looks like you’ve had a full night’s rest, 86% agree skin texture seems refined, 89% agree skin seems softer, 89% agree skin looks smoother, 89% agree skin seems hydrated, 86% agree skin looks healthier, and 88% agree complexion looks more radiant.
