Description

A dermatologic procedure using picosecond-domain lasers to selectively target and fragment melanin in pigmented lesions, promoting natural clearance with minimal thermal damage to surrounding tissue.

Main Uses

Primary clinical uses include non-ablative removal of benign pigmented lesions (e.g., solar lentigines, freckles, café-au-lait macules, nevus of Ota), improvement of melasma (off-label, with caution), tattoo removal (especially multicolored or stubborn inks), and skin rejuvenation via laser-induced optical breakdown (LIOB) stimulating collagen/elastin. Applicable for Fitzpatrick skin types I–IV, with careful protocol adjustment for darker phototypes.

Normal Range

Not applicable — 'Ultra-Picosecond Laser Pigment Removal' is not a laboratory or diagnostic test with numerical biomarkers; it is a cosmetic dermatological procedure using ultrafast laser pulses (typically 450–750 ps pulse duration) to target melanin in pigmented lesions. There are no quantitative 'normal ranges' or reference values.

Low Values - Possible Causes

N/A — This is not a measurable physiological parameter; 'low values' do not exist for this procedure. Clinical outcomes (e.g., insufficient pigment clearance) may result from suboptimal treatment parameters, inadequate fluence, excessive skin cooling, or highly resistant melanin types (e.g., dermal nevus vs. epidermal melasma).

High Values - Possible Causes

N/A — No 'high values' apply. Adverse effects such as post-inflammatory hyperpigmentation (PIH), hypopigmentation, or textural changes may occur due to excessive fluence, overlapping pulses, inappropriate wavelength selection, or treating tanned/dark skin without proper pre- and post-care.
