According to the Mayo Clinic, stretch marks, or striae, are a form of scarring on the skin with an off-color hue. They are caused by the stretching and minor tearing of the dermis, and over time can diminish but not disappear completely. Stretch marks are often the result of the rapid stretching of the skin associated with rapid growth. Stretch marks may also be influenced by hormonal changes associated with puberty, pregnancy, muscle building, hormone replacement therapy for transsexuals, etc. Medical terminology for these kinds of markings includes striae atrophicae, vergetures, stria distensae, striae cutis distensae, striae gravidarum (in cases where it is caused by pregnancy), lineae atrophicae, linea albicante, or simply striae.
Various treatments are available for the purpose of improving the appearance of existing stretch marks, including laser treatments, dermabrasion, and prescription retinoids. Some cream manufacturers claim the best results are achieved on recent stretch marks; however, few studies exist to support these claims. The use of the Dermapen® uses the bodies natural solution for unsightly stretch marks. New collagen growth and stimulation is more effective for reducing and fading stretch marks. The Dermapen does this through Collagen Induction Therapy (CIT).
The Dermapen device allows for appropriate treatment needle depth to activate the cascade of fibroblast and growth hormone steps to generate more skin, collagen and elastin for smooth and healthy colored skin. The skin of the epidermis is noticeably smoother and evens stretch marks as a result.
Your medical professional can consult you on a prescribed treatment. Most patients see improvement with just one treatment, however 5-6 treatments may be necessary. After 5-6 treatments, striae is noticeably improved in texture, and appearance of mature, white striae in skin types I-IV. Four weeks between treatments is necessary to allow the bodies natural skin cycle to complete before another treatment should be performed.
