Dryness and dehydration in the skin can be treated with moisturizers that contain ingredients like hyaluronic acid, glycerin, or ceramides to lock in moisture. Using a gentle, hydrating cleanser without harsh chemicals is important to avoid stripping natural oils. Regularly applying thicker creams or oils, especially after bathing, helps retain moisture. Drinking plenty of water and maintaining a balanced diet rich in omega-3 fatty acids can also support skin hydration from within. For persistent dryness, consulting a dermatologist can help identify the best treatment for your skin type.
