Focus on maintaining your skin’s water content, as many issues—sensitivity, dullness, fine lines, an uneven tone and texture—stem from dehydration. Keeping your skin well moisturised will also help keep the skin barrier healthy—vital for protection against both water loss and external aggressors. Use a hydrating serum such as Glow Recipe’s Plum Plump Hyaluronic Serum, which has a blend of multi-weight hyaluronic acids to keep skin moist. Follow with an antioxidant-packed moisturiser such as ést .lab’s Activ Calm Anti-Stress Hydra Cream, which hydrates and protects against urban pollutants. During the day, slather on Kiehl’s Ultra Light Daily UV Defense Aqua Gel SPF 50/ PA++++ to fend off sun damage and come night, apply a generous layer of LANEIGE’s Cica Sleeping Mask Sleeping Microbiome for intense overnight hydration.
