Exfoliate
When dead skin cells begin to build up on the epidermis, you end up with a dull, rough surface. Chemical exfoliants, such as alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs), can dissolve the debris on the skin that leads to cell turnover. AHAs work well for people with dry or aging skin, while BHAs can be effective for people with oily, acne-prone skin.
Drink enough water
Dehydration weakens the skin barrier, leading to dryness, flakiness, and rough texture. Drinking enough water is important for the health of your skin. You should also look for and use a moisturizer that contains humectants like hyaluronic acid or glycerin, which help keep your skin hydrated and plump.
Sun protection
UV rays break down collagen and elastin in the dermis, leading to roughness, wrinkles, and hyperpigmentation. Apply a broad-spectrum sunscreen daily to prevent photoaging and protect against textural changes.
In a study published in the American Journal of Clinical Dermatology, participants who applied a broad-spectrum sunscreen (SPF 30) for 52 weeks saw significant improvements in skin texture.
Maintain a balanced diet
Nutrition is extremely important for skin health. Eat foods rich in antioxidants, vitamins and healthy fats to help your skin look smoother.
According to research published in Nutrition, a diet high in fat and refined sugar is very harmful to the skin.
