Each and every person may get stretch marks irrespective of age, sex, general health, life situation etc. However, these factors can make a favorable situation for stretch marks in many cases. Stretch marks appear as a result of excessive stretching of the skin for a prolonged period of time, which in turn, results in the rupture of collagen fibers in the skin. This causes cosmetic problems due to the appearance of pinkish or silvery white lines in different parts of the body. Beauty–consciousness is an innate weakness of man. Hence, most of us leave no stone unturned in improving our looks. The skin is considered the mirror of the human body and reflects the physical, mental and emotional status of every individual. Therefore, the care of skin naturally assumes utmost significance in beauty care. The number of people attending beauty clinics and dermatology departments is increasing day by day. Even though skin diseases have a negligible mortality rate, most people are worried about skin problems on account of the social stigma. A person with a disease involving an internal organ may not be as worried as another suffering from a skin ailment in view of the simple reason that everyone can expressly notice the change in the latter in the form of a distortion or plain ugliness.
STRUCTURE OF THE SKIN
The skin has three layers - The outer layer called the epidermis, the inner one called the hypodermis and the dermis in between these two. The epidermis is made up of keratinocytes and melanocytes. The dermis contains fibers made up of proteins such as collagen and elastin with a gel-like ground substance to fill the gap between the protein fibers. The inner hypodermis contains fat and connective tissues with blood vessels and nerves.
Collagen:
It is a structural protein that forms 80% of connective tissues. It acts as a cementing substance between body cells. The rate of tissue repair depends on the production of collagen. Conditions that hamper collagen formation can delay wound healing.
Elastin:
It is also a protein that maintains the elasticity of the skin. Along with collagen and glycosaminoglycans, it forms the connective tissue. The human skin has got several functions such as protection, heat regulation, water balance, excretion etc. It supports the deep body structures and is capable of
Stretch Marks - Prevention and Treatment
stretching to some extent due to the presence of elastic protein fibers in the dermis. But too fast enlargement of the body parts causes excessive stretching of the skin, resulting in the breaking of collagen and elastin fibers of the dermis. This causes a slightly depressed discoloration called stria atrophia or stretch marks. Initially, these marks are slightly pinkish and later become white or silvery in appearance.
