This oil-free gel-cream moisturizer with exclusive aloe bio-ferment and hyaluronic acid penetrates deep into skin’s surface—for hydration that goes over 10 layers deep* and lasts for 100 hours, even after washing your face. Delivers a 174% immediate moisture boost and keeps skin hydrated for 100 hours. This advanced dual-action hydrator with Auto-Replenishing Technology helps skin create its own internal water source to continually rehydrate itself, then locks in moisture for an endlessly plump, healthy-looking glow. For mask wearers, Moisture Surge™ 100H is truly a moisture marvel. It’s proven to help prevent drying and barrier damage from prolonged mask wearing when applied 3x/day for 7 days (compared to masked skin without Moisture Surge™ 100H).
