Intrinsic ageing is an inevitable, genetically determined process that occurs naturally and is affected by the degenerative effects of free radicals, hormonal shifts and the body’s inability to perfectly repair skin damage1. Extrinsic ageing, on the other hand, is a result of lifestyle and environmental factors1.
Likewise, people ask, what is an example of extrinsic aging?
Extrinsic ageing of skin is a distinctive declination process caused by external factors, which include ultra-violet radiation, cigarette smoking, air pollution, among others. Of all extrinsic causes, radiation from sunlight has the most widespread documentation of its negative effects on the skin.
Keeping this in consideration, what is an example of intrinsic aging?
What are the signs of intrinsic ageing? The apparent signs of intrinsic ageing include the loss and descent of underlying fat, leading to hollowed cheeks and eye sockets, as well as loss of firmness and sagging skin as the bones shrink away from the skin due to bone loss.
What is the result of intrinsic skin aging?
Intrinsic aging is an inevitable physiological process that results in thin, dry skin, fine wrinkles, and gradual dermal atrophy, while extrinsic aging is engendered by external environment factors such as air pollution, smoking, poor nutrition, and sun exposure, resulting in coarse wrinkles, loss of elasticity, laxity …
Extrinsic factors are external to the individual and can include variables such as the type of sport, exposure to the sport, training, and playing environment . Intrinsic factors are internal personal factors that can be further dichotomised into modifiable and non-modifiable risk factors.
Diseases of old age – aspects of aging that are not part of the normal, species universal process of aging – are referred to as secondary aging. Some of the most common diseases of aging include Alzheimer’s dementia, cancer, diabetes, and cardiovascular disease.
Extrinsic skin aging relates to the external, environmental and lifestyle factors that affect our skin — and often accelerate the skin-aging process. These factors include elements that produce free radicals, like pollution, UV light, cigarette smoke, stress and more.
The most common signs of extrinsic ageing are thinning of the skin, laxity, fragility and the increased appearance of wrinkles. Sun exposure can also lead to pigmentation or sun spots and accentuate premature wrinkling.
Intrinsic motivation is the act of doing something without any obvious external rewards. You do it because it’s enjoyable and interesting, rather than because of an outside incentive or pressure to do it, such as a reward or deadline.
With aging, the outer skin layer (epidermis) thins, even though the number of cell layers remains unchanged. The number of pigment-containing cells (melanocytes) decreases. The remaining melanocytes increase in size. Aging skin looks thinner, paler, and clear (translucent).
- Age. As you get older, your skin naturally becomes less elastic and more fragile. …
- Exposure to ultraviolet (UV) light. Ultraviolet radiation, which speeds the natural aging process, is the primary cause of early wrinkling. …

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.
