Refreshing Clinique moisturizer chosen by everyone. Lightweight, oil-free gel-cream that penetrates deeply and lasts 100 hours. What it does: Many factors can dehydrate your skin, such as weather, pollution, blue light, time spent in the sun, mask-wearing, air travel, air conditioning, and heating. Counteract everyday dehydration. This oil-free gel-cream moisturizer with Aloe Bioferment + HA Complex penetrates deep into the skin's surface - for 100 hours of steady hydration. Plus, Auto-Replenishing Technology helps the skin create its own internal water source for continuous hydration and then locks in moisture. Skin feels soothed with hydration in 3 seconds and continues to glow. Provides a smooth base for makeup application. Safe for sensitive skin. For mask wearers, Moisture Surge 100H is truly a hydration miracle. It has been proven to help prevent dryness and barrier damage from prolonged mask use when applied 3 times a day for 7 days (compared to masked skin without Moisture Surge 100H).
