Exposure to ultraviolet light, UVA or UVB, from daylight accounts for 90% of the indicators of premature skin ageing. Most of the photoaging effects occur by age 20. The quantity of damages to the skin caused by the sun is decided by the total lifetime quantity of radiation exposure and the person's pigment protection.
Changes in the epidermis due to the sun include thinning of the skin and the expansion of skin abrasions such as actinic keratosis , basal cell carcinomas, and squamous cell carcinomas.
Sunlight Effects on the Dermis
In the dermis, sun effects cause collagen to break down at a higher rate than with just chronologic ageing. Daylight damages collagen fibers and causes the accumulation of abnormal elastin. When this sun-induced elastin accumulates, enzymes called metalloproteinases are produced in big quantities. Normally, metalloproteinases transform sun-injured skin by manufacturing and reforming collagen. However , this process doesn't always work best and some of the metalloproteinases basically break down collagen. This leads to the formation of disorganised collagen fibers known as solar scars. When the skin repeats this imperfect rebuilding process again and again wrinkles develop.
Oxidizing Agents and Wrinkles
Free radicals aren't stable oxygen molecules that have only 1 electron instead of two. Because electrons are found in pairs the molecule must scavenge other molecules for another electron. When the second molecule looses its electron to the 1st molecule, it must then find another electron repeating the process. This process can damage cell function and change genetic material. Free radical damage causes wrinkles by activating the "metalloproteinases" that break down collagen. There are several factors that start this cascading process including exposure to even small amounts of UV radiation in daylight, smoking, and exposure to air pollution.
Hormone Effects and Wrinkles
It's probable that there are skin changes as a result of the hormonal effects of menopause or decreased estrogen production. But studies in humans have not documented which skin changes are peculiar to decreased estrogen and which skin changes are a result of sun exposure or just normal chronological aging. In animal experiments absence of estrogen could cause a lowering in collagen levels of 2% each year and a decrease in skin thickness of 1% a year.
Muscle Use and Wrinkles
Habitual expressions cause the skin to wrinkle as it looses pliability. Scowl lines between the eyebrows and crows feet radiating from the corners of the eyes develop as the miniscule muscles in those areas permanently contract.
Gravity and Wrinkles
The effects of gravity make the relaxing of the skin more apparent as skin sags more. This is the cause of jowls and sagging eyelids.
The reason of why most wrinkle creams don't work may very well emerge from understanding the skin matrix is answerable for the skin's mechanical properties, including firmness, strength, suppleness, and elasticity. Wrinkles are little furrows, ridges, or creases on a normally smooth surface, caused by crumpling, folding, or shrinking in a skin matrix impacted by atrophy, a condition indicated by precisely the reverse of those just discussed before: firmness, strength, suppleness, and pliancy.
