노화되면 피부는 어떤 변화가 있을까? skin aging

피부는 나이가 들면서 많은 변화가 발생합니다.

구체적인 요인들을 정리해 보면 아래와 같습니다. 

Skin Changes That Come With Age

As we grow older, changes like these naturally occur:

• Skin becomes rougher.
• Skin develops lesions such as benign tumors.
• Skin becomes slack. The loss of the elastic tissue (elastin) in the skin with age causes the skin to hang loosely.
• Skin becomes more transparent. This is caused by thinning of the epidermis (surface layer of the skin).
• Skin becomes more fragile. This is caused by a flattening of the area where the epidermis and dermis (layer of skin under the epidermis) come together.
• Skin becomes more easily bruised. This is due to thinner blood vessel walls.

Changes below the skin also become evident as we age. They include:

• Loss of fat below the skin in the cheeks, temples, chin, nose, and eye area may result in loosening skin, sunken eyes, and a "skeletal" appearance.
• Bone loss, mostly around the mouth and chin, may become evident after age 60 and cause puckering of the skin around the mouth.
• Cartilage loss in the nose causes drooping of the nasal tip and accentuation of the bony structures in the nose.

Sun and Your Skin

Exposure to sunlight is the single biggest culprit in aging skin.

 

Over time, the sun's ultraviolet (UV) light damages certain fibers in the skin called elastin. The breakdown of elastin fibers causes the skin to sag, stretch, and lose its ability to snap back after stretching. The skin also bruises and tears more easily and takes longer to heal. So while sun damage may not show when you're young, it will later in life.

Nothing can completely undo sun damage, although the skin can sometimes repair itself. Lasers can also help reverse some of the damage. So, it's never too late to begin protecting yourself from sun exposure and skin cancer. You can delay changes associated with aging by staying out of the sun, covering up, wearing a hat, and making a habit of using sunscreen.
