Laser Pigmentation and Spot Removal (K-Laser)

Hyperpigmentation — the localised excess of melanin that produces brown, dark or discoloured patches — is one of the most common aesthetic skin concerns. Solar lentigines (commonly called age spots or sun spots) arise from chronic UV exposure that stimulates melanocytes in localised clusters to produce excess pigment, creating flat, sharply defined brown marks most visible on areas with the greatest cumulative sun exposure: the face, the backs of the…

At Derma-plus Tábor, MUDr. Irena Hejcmanová uses the K-Laser Blue Derma to selectively target melanin-dense tissue. The laser energy is absorbed preferentially by melanin — the dark pigment in the lesion — converting to heat that disrupts the melanin granules and causes controlled injury to the pigmented cells. The body's immune system then removes the broken-down pigment debris through macrophage clearance over the following two to four weeks,…

Before treatment, dermoscopic assessment is mandatory: solar lentigines have a characteristic 'moth-eaten' border and uniform pigment network under dermoscopy, distinctly different from the irregular pigment networks and atypical structures seen in early melanoma or dysplastic naevi. This assessment step protects against treating a potentially malignant lesion with ablation rather than excision and histopathology. Only lesions confirmed as benign…
