SKIN CHANGES WITH AGE
Skin Aging
Skin changes with normal aging processes and the environmental
factors we subject it to, such as cigarette
smoke, toxic
foods, and sunlight.
The most commonly recognised changes with age are fine
lines, wrinkles and loss of skin tone or elasticity.
But other changes also occur, some beneath the surface
of the skin.
Skin has optical depth, meaning our eyes perceive discolorations
on the surface and in underlying layers. This discoloration
can be subtle or overt. Changes such as uneven chromophore
distribution and a decrease in light reflection can
make the skin look older.
IIn particular, uneven distribution of one chromophore,
melanin, is related to cumulative UV damage, and commonly
iincreases perceived age.
The distribution of light reflecting molecules, called
chromophores, correlates with perceived attractiveness.
Chromophores directly affect how the human eye perceives
qualities such as luminosity in young skin or dullness
in aging skin.
Skin Aging Studies
IIn one ineresting study design to elicit what viewers
judged as an attractive skin
tone, or color, employed high-resolution digital
images from 169 female subjects aged 10-70 years. Images
from three angles: frontal, left and right profile or
these subjects were enhanced digitally to remove potential
age-defining features such as facial furrows, folds,
lines and wrinkles at the mouth, nose and eye area.
The resulting images were then fitted to a standardized
virtual 3-D skull, where variables such as overall face
shape, lighting, camera angle, eye color/form and hairstyle
were eliminated, leaving composite skin pigmentation
(tone) as the only variable.
Raters were asked to estimate the age of stimuli faces
as well as answer questions relating to general attractiveness,
health and skin attributes.
The results showed overwhelmingly that skin tone does
have a significant impact on perceived age and attractiveness.
This is interesting for the aging population who largely
focus on skin product to remove wrinkles and spot pigmentation,
but don't appear to concentrate to the same extent on
skin tone.
Skin Changes with Age
Different changes occur at different age periods.
