Laser treatments are complicated and certainly can be expensive, but they do have their good points, too! Lasers are used to focus on tiny areas of scar tissue and gently work them away with concentrated heat. The procedure does not involve the kind of pain that chemical peels or collagen injections do, and if done well it can leave the skin in a better state than with dermabrasion or other scrubbing methods.
Although some cases of acne eventually disappear by themselves, even the most aggressive treatments will take 6-8 weeks to show any results. Even after this amount of time you may not see any improvement as acne treatment is often a case of trial and error for dermatologists and their patients. Everyone is different and finding the perfect combination of approaches may take some time.
The gland's secretion, sebum, is formed by fatty degeneration of the epithelial cells of the gland. The entire sebaceous cells and its contents are then eliminated into the duct (Holocrine process) and is excreted on to the skin surface through the lumen of the hair follicle. Sebaceous gland activity is under hormonal control. Androgens are the most potent stimulants of seburn production while oestrogens suppress sebaceous gland activity. Seburn contains a complex mixture of lipids i.e., triglycerides, wax esters, squalene, cholestrol ester and cholesterol. The sebum acts as a lubricant and controls moisture loss from the epidermis. Another advantage of sebum is protection of skin from fungal and bacterial infection.
