Skin pigmentation is a result of irregular production and deposition of melanin by the melanocytes. Melanocytes are cells that produce pigment. Production of melanin is dependent on sun exposure, and is a natural protective mechanism of the skin against UV. As much as 80% of UV damage occurs in childhood, not becoming apparent until years later, usually first appearing as mild freckling, becoming more severe with age.
Superficial pigmentation is restricted to the epidermis, while deeper pigmentation occurs in the dermis and often originates from chronic superficial pigmentation, making it difficult to treat. Laser and light platforms are available for effectively treating pigmented lesions and can be customized to the depth of the lesion and the unique concerns of the patient.
Epidermal pigmented lesions such as freckles, age spots and sun spots are removed via Q-Switched Nd:YAG lasers. The extremely short pulse acts to ‘smash’ the excessive pigment into tiny pieces which is then removed by the body’s natural filtering system. What’s left behind is normal, healthy looking skin.
Epidermal pigment responds well to 532nm Q-Switch, 577nm yellow light, 695nm Ruby, and IPL treatments.
The IRIS Q-Switch Nd:YAG laser offers impressive results using a 532nm wavelength. For darker skin types, the TattooStar Combo Q-Switch laser can treat at 695nm which minimises the risk of burns.
The Superbium IPL handpiece offers optimal results for full face freckle treatments.
