The AGING DERMIS
The graph shows the relationship between age and the body's synthesis of elastin and collagen.
COLLAGEN is synthesized (produced) by the body up to the age of 60. There is absolutely no need to supplement the skin with collagen. Nature itself looks after that.
ELASTIN is synthesized (produced) by the body from the embryonic stage but reaches its maximum at the end of adolescence decreasing from age 25 - 30 and stopping altogether by age 40 - 45 years.
During a conference on dermo-chemistry, Professor H. BOUISSON explained how the physiological ageing process was associated with a progressive loss of elastin in the dermis and arteries. In fact, the biological age of a person can be histologically estimated on a skin biopsy by means of the quantity of elastin fibers contained in the dermis - the state of the arteries may also be deduced as the degradation of the elastic fibers spreads simultaneously in the skin and the blood vessels.
This decrease or stopping of the elastin synthesis adds to the breakdown of the elastic fibers due to lipid and calcium deposits.
The concomitance of both phenomena:
- the inhibition or stopping of elastin synthesis,
- the deterioration of the elastic fibers
leads to a progressive loss of skin elasticity and the appearance of wrinkles as skin ages.
