HimyRiews A face should look healthy, smooth, and relaxed. The skin should be hydrated, exfoliated, and moisturized to look its best. A diet with plenty of antioxidants, essential fatty acids, and plenty of water will help your skin stay healthy. Exfoliating with a scrub or a chemical peel every few days can help improve rough texture and reduce blackheads. Using a moisturizer with skin-repairing ingredients like retinol, alpha hydroxy acids, or collagen can also make your skin look smoother and more radiant. If you have acne, you can use acne medication, exfoliate regularly, and use a daily moisturizer. Smoking can worsen the appearance of your skin and increase your risk of wrinkles. Acne is also a risk factor for age spots.
The skin is the largest organ in the body and it protects the body from infection, dehydration, and damage from ultraviolet light. There are three main types of skin: epidermis, dermis, and hypodermis. The epidermis is where most of our visible skin cells are produced and located. The dermis is where we find our muscles, blood vessels, sweat glands, hair follicles, nerves, bones, and many other structures that make up our bodies. The hypodermis is where fat tissue (liposuction) and connective tissue (tumescent liposuction) are found. Facial sun protection must be used in order to protect the skin from the harmful effects of ultraviolet radiation (UVR) and excessive exposure to solar radiation. The skin is constantly exposed to UVR, which is present in sunlight as well as artificial sources such as tanning beds and sun lamps.
UVR causes damage by causing free radicals and reactive oxygen species (ROS). ROS are biological molecules produced by cells that have an unpaired electron, or an unstable configuration that results in a chemical reaction resulting in the formation of other molecules with unpaired electrons. Free radicals can cause damage by destroying DNA and causing mutations, cell death, and other health problems. UVR also causes photodamage, which is caused by visible light exposure which induces oxidative stress on collagen fibers resulting in wrinkles, pigmentation changes, loss of elasticity, and increased risk for premature aging. In addition to causing photoaging, there are also other effects of ultraviolet light such as immunosuppression leading to skin cancer
