1. Clean your skin. Choose your skin cleanser based on whether your skin is dry or oily. If you have dry skin, choose a mild cleaning agent and avoid products such as toners, which contain alcohol. For oily skin, choose a soap that removes the oil and clean your skin more frequently throughout the day.
2. Protect your skin from the sun. Choose a broad-spectrum sunscreen with an SPF of 30 or higher and wear it every day. Higher SPFs are useful if you plan to spend hours outdoors, but if you spend most of your time indoors, SPF 30 is generally sufficient. If you have sensitive skin, choose a sunscreen product designed for sensitive skin.
3. Treat your skin's particular needs. For dry skin, there are plenty of effective and inexpensive moisturizers. There are also plenty of affordable over-the-counter products that can reduce lines and wrinkles, fade brown spots, or combat acne.
4. Don't Wear Makeup to Bed. When you're tired, it can be tempting to go to bed without washing your face. But leaving makeup on your skin can clog your pores and cause acne. So wash it off with a gentle cleanser or makeup remover.
