Microdermabrasion is partially or completely removed by light abrasion, to remove sun-damaged skin and to remove or lessen scars and dark spots on the skin.
The procedure is not very painful and requires no anaesthetic. Microdermabrasion can be used medically for scar removal when the scar is raised above the surrounding skin, but is less effective with sunken scars. There is very little, if any, evidence that microdermabrasion stimulates collagen formation. Microdermabrasion can also be used for treatment of acne, but must be repeated periodically to be effective. Microdermabrasion should not be used on patients who have taken the medication Accutane (Isotretinion) in the previous twelve months.
Different methods include mechanical abrasion from jets of zinc oxide or aluminum oxide crystals, fine organic particles, or a roughened surface. Particles are removed with a wand/handpiece through which the abrasive particles come. The term dermabrasion itself refers to the more severe medical procedure carried out under general or light anesthesia.
• Crystal microdermabrasion
Crystal microdermabrasion systems are the traditional treatment of choice and rely on tiny crystals that are blasted onto the skin to perform the exfoliating process. Although the crystal microdermabrasion system is still widely used, the introduction of alternatives has led to a trend away from this treatment system.
• Diamond microdermabrasion
Diamond microdermabrasion systems operate without the need for crystals. The exfoliation process occurs when a diamond tipped head makes contact with the skin and abrades against it. In both crystals and diamond microdermabrasion systems the dead skin cells are sucked away from the face.
Microdermabrasion is a procedure where tiny particles "sand" or "polish" the skin and gradually remove scarred or discolored epidermal tissue. When you use a home microdermbrasion system the surface skin cell turnover will be enhanced and the skin will be visibly fresher. Home microdermabrasion creams with active ingredients, are focused on skin renewal and accelerate rebuilding of healthy collagen skin cells after microdermabrasion, laser resurfacing or harsh peels. For depressed scars, such as pitted acne scars, subcision with needles is often used by estheticians to break up the deeply buried scar tissue, and a home microdermabrision system then speeds up new healthy skin remodeling: the orderly process of laying out new collagen and elastin fibers.
The reduction of scars, lesions, and stretch marks from the skin is dependent on a process called "skin remodeling". The skin is designed to heal wounds fast to prevent blood loss and infection. Scars are made from a quickly formed "collagen glue" that the body deposits into an injured area for protection and strength.
In the optimal skin healing, the wounded skin is rapidly closed, then the healed area is slowly reconstructed to remove the residual collagen scars and blend this skin area into nearby skin. Scar collagen is removed and replaced with a mixture of skin cells and invisible collagen fibers. One way to accelerate remodeling is to induce a small amount of controlled skin damage with a needle, laser, microdermabrasion, scrubbing massage or other means, and then let the body repair processes rebuild the skin area. A second method is to use skin healing accelerators to increase the body's natural healing processes to obtain even better results.
