But recently, he always can’t help but feel particularly uncomfortable skin, age spots, wrinkles are more than others. This makes the old man very depressed. ”The skin of the elderly is actually very fragile and can easily be injured if not cared for.” Experts say that many elderly people have wrinkles and age spots on their faces, backs of their hands and other exposed parts, mostly due to photoaging, which is more sun exposure. After old age, the skin began to thin, friction and pulling may make the skin cracking, fragile blood vessels more can not afford to ravage. Even small injuries often leave bruises, purple spots, hematomas. Aging skin’s ability to repair itself is greatly reduced, and wounds may take four times longer to heal than they did in their prime, which can cause problems such as bed sores or inflammation. In addition, problems such as diabetes, cardiovascular changes, and decreased immunity can all affect the rate of wound healing. The primary function of wearing sunscreen is not only to prevent tanning, but also to avoid sun-induced skin damage and subsequent premature aging. In addition, physical sun protection also needs to be strengthened, such as wearing a wide-brimmed hat, holding an umbrella, wearing long-sleeved dark clothing, and wearing sunglasses, all of which can block UV rays. Seniors like to walk, the sun is not strong in the morning, dusk, also need to pay attention to sun protection. It should be reminded that the sun is sufficient for early exercise. You should try to avoid going out from 10 am to 2 pm when the sun is at its strongest.
