Laser Pigmentation and Spot Removal (K-Laser)

Targeted removal of pigmented patches and age spots using the K-Laser Blue Derma diode laser, which delivers precise energy to melanin-rich tissue to break down excess pigment and allow the body to clear it over two to four weeks. The treatment addresses solar lentigines (sun spots), post-inflammatory hyperpigmentation and other discrete pigmented patches on the face, décolleté and hands. MUDr. Irena Hejcmanová assesses each lesion dermoscopically before treatment to distinguish pigmentation from potentially melanocytic lesions requiring a different approach.

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 hands, the forearms and the décolleté. Post-inflammatory hyperpigmentation (PIH) develops after skin injury or inflammation — acne, dermatitis, laser or peel treatments — and is driven by the inflammatory cascade triggering melanocyte overactivation. 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, progressively lightening the treated area. Surrounding skin, which contains less melanin, absorbs far less energy and is not damaged. 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 pigmentation proceed to laser removal. The procedure itself is brief — a few minutes for small spot clusters — and uses topical anaesthetic cream applied beforehand to minimise discomfort from the laser pulses. Immediately after, the treated area may appear darker and slightly swollen as the disrupted melanin oxidises; this darkening (the 'frosting' phase) then gradually lightens over two to four weeks as clearance proceeds. Sun protection with SPF 50+ is essential throughout the healing phase and afterwards to prevent repigmentation. In patients with deeper dermal pigmentation or resistant PIH, a course of two to three sessions may be recommended for complete clearance.
