The sun is the main cause of premature skin aging. A number of other things can also cause our skin to age faster. To stop premature skin aging, dermatologists recommend: 1. Daily sun protection. Whether you’re at the beach or running errands during the day, sun protection is essential. You can choose shade, wear long-sleeved shirts, and use sunscreen with SPF 30 or higher (for skin that is not covered by clothing). 2. Don’t intentionally try to get a tan. Any UV rays can accelerate skin aging. 3, do not smoke. Smoking accelerates the aging of the skin. Cause wrinkles, yellowing and dull face. 4, avoid repeated facial expressions. When facial expressions are made, the local muscles contract. If the same muscles are contracted repeatedly for years, these expressions may persist. Wearing sunglasses helps the wrinkles caused by squinting. 5. Eat a balanced, healthy diet. Adequate fresh fruits and vegetables help prevent damage to the skin caused by aging. Some studies suggest that contains many sugars or fine carbohydrates may accelerate aging. 6, less alcohol. Alcohol is not good for the skin, leading to dehydration, over time, damage to the skin, making people look older. 7, most days of the week to participate in exercise. Some studies have found that moderate exercise can improve circulation, strengthen the immune system, and thus the skin looks younger. 8, gently cleanse the skin. Cleaning the skin with force can stimulate the skin, thus accelerating skin aging. A gentle bath helps to clear dirt, cosmetics, and other things that may irritate the skin. 9. Limit the number of times you wash your face routinely no more than 2 times, and you need to wash your face after sweating. Wash your face once in the morning and once in the evening, and you need to wash your face after a lot of sweating. Sweating, especially with a hat or helmet, tends to irritate the skin, so you should wash your face as soon as possible after sweating. 10. Use facial emollients every day. Emollients help the skin lock in moisture and make us look younger. 11.Stop using skin care products that cause a stinging or burning sensation. A burning or tingling sensation in the skin means that the skin is irritated and thus appears older. If aging skin bothers you, see a dermatologist. New treatments and non-invasive methods can smooth out wrinkles, tighten skin, improve facial expressions, and make people appear younger.
