Stretch marks are the effect of skin stretching and cortisone increasing in your system. Cortisone is a hormone naturally produced by your adrenal glands. Having too much of this hormone can make your skin lose its elasticity. Stretch marks will generally appear as bands of parallel lines on your skin and are usually a different color and texture than your normal skin. They commonly appear during or after pregnancy, when you quickly gain weight, and in adolescents who have frequent growth spurts. Stretch marks are found mostly on your stomach, breasts, upper arms, thighs, and buttocks. Skinlastiq Medical Laser Cosmetic Spa offers patients a non-invasive solution that can help reduce the appearance of stretch marks, as well as improve the texture and tone of your skin.
