Background and aims: The selective removal of tattoos and benign cutaneous pigmented lesions with laser energy evolved rapidly with the development of the nanosecond-domain Q-switched laser (ns-laser). Recently, however, a series of picosecond-domain lasers (ps-lasers) with pulsewidths less than 1 ns has become commercially available, enabling more efficient and faster removal of pigmented lesions in the field of dermatologic laser surgery. Rationale behind the ps-laser: The efficacy of the ns-laser depended on the theory of selective photothermolysis, whereby an extremely short pulse width was delivered less than the thermal relaxation time (TRT) of a target...

Pigmentation disorders are commonly diagnosed, evaluated, and treated in primary care practices. Typical hyperpigmentation disorders include postinflammatory hyperpigmentation, melasma, solar lentigines, ephelides (freckles), and café au lait macules. These conditions are generally benign but can be distressing to patients. Appropriate dermatologic history, skin examination, and skin biopsy, when appropriate, can help exclude melanoma and its precursors. In addition to addressing the underlying condition, hyperpigmentation is treated with topical agents, chemical peels, cryotherapy, light or laser therapy, or a combination of these methods...

There is an increasing demand for imaging tools in clinical dermatology that can perform in vivo wide-field morphological and functional examination from surface to deep tissue regions at various skin sites of the human body. The conventional spectral-domain optical coherence tomography-based angiography (SD-OCTA) system is difficult to meet these requirements due to its fundamental limitations of the sensitivity roll-off, imaging range as well as imaging speed. To mitigate these issues, we demonstrate a swept-source OCTA (SS-OCTA) system by employing a swept source based on a vertical cavity surface-emitting laser...
