Effect of Cold Air Cooling on the Incidence of Post Inflammatory Hyperpigmentation Following Laser Treatment
Summary
- To investigate the benefit of epidermal cooling on the incidence of post inflammatory hyperpigmentation after laser irradiation
Description
- 70% incidence of post inflammatory hyperpigmentation has been reported following a Q-switched nd:YAG laser treatment of acquired bilateral nevus of Ota-like macules.
- We assumed that epidermal cooling may minimize the non-specific injury to the epidermis caused during laser irradiation, leading to the decreased incidence of post inflammatory hyperpigmentation.

Medical and Biotech [MESH] Definitions
Nevus, Pigmented
A nevus containing melanin. The term is usually restricted to nevocytic nevi (round or oval collections of melanin-containing nevus cells occurring at the dermoepidermal junction of the skin or in the dermis proper) or moles, but may be applied to other pigmented nevi.
Nevus, Halo
A benign skin lesion characterized by a zone of depigmentation surrounding the nevus.
Cryoanesthesia
ANESTHESIA achieved by lowering either BODY TEMPERATURE (core cooling) or SKIN TEMPERATURE (external cooling).
Nevus, Intradermal
A nevus in which nests of melanocytes are found in the dermis, but not at the epidermal-dermal junction. Benign pigmented nevi in adults are most commonly intradermal. (Stedman, 25th ed)
Nevus Of Ota
A macular lesion on the side of the FACE, involving the CONJUNCTIVA and EYELIDS, as well as the adjacent facial skin, SCLERA; OCULOMOTOR MUSCLES; and PERIOSTEUM. Histological features vary from those of a MONGOLIAN SPOT to those of a BLUE NEVUS.
Clinical Trials
Non-Invasive Cooling of Fat Cells
The purpose of this study is to evaluate a non-invasive cooling device to determine if cold exposure will consistently result in a reduction of subcutaneous fat.
