What should you know about Quanta Discovery pico laser?

A clinician assesses the colour, depth, and cause of the target area before choosing the wavelength and energy. The device may be considered for concerns such as [Melasma](/conditions/melasma/), [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/), [Sun Spots](/conditions/sun-spots/), [Dark Patches On Skin](/symptoms/dark-patches-on-skin/), or [Uneven Skin Tone](/symptoms/uneven-skin-tone/). Pico pulses deliver energy in an extremely brief burst, which can fragment pigment while limiting prolonged heat compared with some conventional approaches. It is still a medical procedure: temporary redness, swelling, tenderness, crusting, or a change in pigmentation can occur.

Tell the clinician about recent tanning, active rashes, cold sores, medicines, previous pigment changes, and any tendency to form raised scars. Arrive with clean skin and follow instructions about products that may irritate the area. After treatment, use gentle cleansing, prescribed ointment if advised, and diligent sun protection. Do not pick flakes or crusts, and pause unapproved exfoliants until the skin has settled. A consultation can also compare [Picosecond Laser](/technology/picosecond-laser/) with [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/) or [Laser Toning](/treatments/laser-and-energy/laser-toning/).

Contact the treating clinic promptly if pain is worsening rather than easing, blisters spread, the area becomes increasingly warm or swollen, or drainage develops. Seek urgent medical help for facial swelling affecting breathing or vision, or for a widespread blistering reaction. New, changing, bleeding, or non-healing pigmented lesions need diagnostic assessment rather than cosmetic laser treatment.

Which pigment or skin feature are you treating, and how will you distinguish it from a lesion needing examination? Which wavelength and settings suit my skin tone? What reactions should I expect, how should I protect the area, and what is the plan if pigmentation becomes darker or lighter?
