• Pigmentary changes (hypopigmentation and hyperpigmentation)
• Nerve damage (particularly in areas where nerves lie close to the surface of the skin, on fingers, wrist, area behind the ear)
• Shards of frozen ice (minor shards of frozen ice may blow out that will thaw on contact with healthy skin)
• Hair follicle damage and scarring (especially when treating lesions on sites with coarse terminal hair)
