Great looking skin is smooth, radiant, glowing, firm, unlined and "poreless". The key to achieving this is prevention and early intervention. Skin aging can begin as early as age 25. By 60 skin has thinnned and can no longer fight the effects of gravity. Not only does genetic aging affect the skin, so does sun exposure. Sun exposure can account for as much as 90% of age-associated changes in the skin's appearance. Skin aging is the slow accumulation of damage. To counteract this, sun exposure and tanning must be eliminated and a comprehensive program combining professional skincare with clinical treatment solutions must be implemented.
