What should you know about fractional pico laser?

A picosecond laser delivers energy in extremely brief pulses. With a fractional handpiece or pattern, the energy is distributed across small treatment zones rather than covering every millimeter. The goal may be to break up pigment or stimulate remodeling with limited surface disruption. It can be discussed for [Melasma](/conditions/melasma/), [Sun Spots](/conditions/sun-spots/), post-inflammatory marks, or uneven tone, but the cause and depth of pigment matter.

Temporary redness, swelling, sensitivity, pinpoint crusting, or darkening of treated spots can occur. Pigment can also become lighter or more noticeable during healing. A fractional pico approach is not interchangeable with every picosecond treatment, so the clinician should explain the device, handpiece, and intended endpoint.

Tell the clinic about recent sun exposure, tanning products, active rash, infection, cold sores, pregnancy plans, and a history of pigment changes after skin injury. Follow instructions about stopping irritating products. After treatment, cleanse gently, moisturize, leave crusts undisturbed, and use broad sun protection as directed. Avoid heat, rubbing, and unapproved bleaching or exfoliating products while the skin settles. If your concern is a symptom such as [Dark Patches On Skin](/symptoms/dark-patches-on-skin/), ask whether its cause has been assessed before treating its appearance.

Contact the clinic if pain or swelling keeps increasing, blisters spread, drainage appears, or redness becomes hot and expanding. Fever may indicate infection. Get urgent help for breathing difficulty, widespread hives, or swelling that affects the eyes or vision.

Ask whether the pigment is suitable for laser treatment, what settings and fractional pattern will be used, how recurrence will be managed, and which signs indicate irritation, infection, or a pigment reaction.
