Laser Cosmetic Solutions offers patients DOT Therapy (Dermal Optical Thermolysis), one of the latest procedures in laser skin resurfacing and skin rejuvenation.

DOT Therapy is a tool used to help reduce the signs of aging of the skin.   This procedure delivers CO² laser energy targeting the face, neck, decolletage, hand and arms.  DOT Therapy helps to improve sun damage, brown spots, wrinkles, fine lines, and acne scarring with possible minimal downtime or discomfort.

The SmartXide DOT laser system has the capability which may deliver a customized pattern of tiny, micro-sized dots, rather than treating the entire skin surface, so healing is may be faster. DOT Therapy has been introduced through an alliance between Eclipsemed, Ltd., aesthetic laser distributor, and DEKA, laser manufacturer.

The SmartXide DOT system is a CO² (carbon dioxide) laser. The CO² laser is a common type of laser used for skin resurfacing. CO² lasers of the past covered the entire surface of the skin, which could result in a significant amount of downtime to heal, discomfort for the patient and prolonged redness of the skin. In addition, the older CO² lasers could not treat non-facial areas like the neck and decolletage easily because skin in these areas did not heal as well as the face.

DOT Therapy has received clearance from the Food & Drug Administration.
