Skin Tightening Procedures include the use of laser or radio frequency devices to safely heat deep dermal tissues causing collagen reduction in the reticular (lower) dermis and coagulation of tissue in the papillary (upper) dermis. Controlled wounding of the papillary dermis allows for new collagen formation and remodeling while reduction of collagen to the reticular dermis allows for contraction of tissue. This is a non-ablative type of procedure and typically include Class II light energy devices and requires multiple treatments for the desired effect. Typically, these devices are safe for all skin types and has multiple non-FDA uses such as the shrinkage of sebaceous glands associated with moderate and severe acne. It requires a number of treatments and is dependent upon patient tissue response, body location, and the light energies introduced to the skin. Remodeling of collagen within tissue occurs in as little as 3 weeks and can last as long as 9 to 12 months depending upon the individual. Areas that can be treated successfully include thighs, abdomen, knees, face, and neck areas.
