Dry skin typically requires more moisturizing due to its naturally low levels of sebum production and moisture retention. This type of skin often feels tight, looks dull, and may show signs of flakiness or irritation. The lack of moisture in dry skin can lead to a compromised skin barrier, making it essential to consistently apply moisturizers that contain hydrating ingredients such as hyaluronic acid, glycerin, or ceramides. These ingredients help to attract and retain moisture, providing the hydration that dry skin desperately needs.

In contrast, oily skin produces excess sebum, which can lead to a shiny appearance and problems like acne, but it generally does not require as much moisturizing. Normal skin is balanced, with neither excessive oiliness nor dryness, so it typically needs moderate moisturizing. Combination skin contains both oily and dry areas, which means each part may need different treatments but does not necessarily require excessive moisturization overall.
