Moisturizer is a fundamental skincare product designed to replenish and retain the skin's natural moisture. It forms a protective barrier that prevents dehydration and shields against environmental stressors like pollution and harsh weather. Available in various formulations—creams, gels, lotions, and balms—moisturizers cater to all skin types, including oily, dry, sensitive, and combination. Many products are enriched with ingredients like hyaluronic acid, ceramides, and natural oils to boost hydration, repair the skin barrier, and enhance elasticity. Regular use of moisturizer helps improve texture, soothe irritation, and maintain a youthful, healthy glow.
