A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell.Muscles are composed of tubular cells called myocytes, known as muscle fibers in striated muscle, and these cells in turn contain many chains of myofibrils. Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. 2  Actin, when polymerized into filaments, forms the ladder along which the myosin filaments climb to generate motion. 3  Thick filaments consist primarily of the protein myosin, held in place by titin filaments.

Fraxel Laser is one of the many types of Fractionated Lasers available on the market today. Although the Fraxel was the first Fractional Laser created, they all work on the same principal.

This heat tunnel is deep enough to cause the stimulation of new collagen fibers which results in an improvement of the acne scar.

Fraxel Repair is the procedure of choice for deep lines, hard-to-erase lip lines, pronounced photodamage, sagging face and neck skin, facial wrinkles and discolorations, age-related/sun-damaged rough skin texture, acne scars and surgical scars.he advantage of Fraxel Repair is the use of carbon dioxide laser beams, which not only minimize wrinkles and discolorations, but also have the ability to tighten skin.
