They are most likely the result of the rapid stretching of the skin associated with periods of quick growth (common in puberty) or fast weight gain (e.g. pregnancy or muscle building).
Stretch marks are most likely to appear in places where larger amounts of fat are stored, but appear anywhere on the body.
The glucocorticoid hormones responsible for the development of stretch marks affect the epidermis by preventing the fibroblasts from forming collagen and elastin fibers, necessary to keep rapidly growing skin taut. This creates a lack of supportive material, as the skin is stretched and leads to dermal and epidermal tearing.
Stretch marks can be treated using skin abrasion treatment technology. A superficial abrasion of the skin tissue triggers the body’s own natural repair mechanism which stimulates the production of new collagen and elastin fibres. Consequently, skin abrasion technology can have a remarkable softening action on stretch marks. Although unlikely to completely remove the stretch marks a course of skin abrasion treatments should certainly cause stretch marks to significantly fade.
Generally, the newer the stretch mark the greater will be the response to skin abrasion treatments.
There are several skin abrasion technologies available that can assist in removing the stratum corneum (dead outermost surface of the skin).
CACI Orbital Microdermabrasion uses an abrasive rotating head to gently exfoliate the dead skin and CACI Ultrasonic Peel provides a less aggressive alternative to traditional Orbital Microdermabrasion methods of skin exfoliation.
