What should you know about pico laser 532?

The device delivers very brief pulses that create a photoacoustic effect, fragmenting some pigment without relying only on prolonged heating. The 532 nm wavelength is commonly selected for pigment closer to the skin surface. A clinician still needs to distinguish a sun spot from melasma, post-inflammatory hyperpigmentation, or another lesion before treatment. Search the related guides for [Melasma](/conditions/melasma/) and [Sun Spots](/conditions/sun-spots/) to understand why diagnosis matters.

Tell the practitioner about recent tanning, active rashes, cold sores, medicines, and previous pigment changes after procedures. Arrive with clean skin and follow instructions about products that may irritate the area. Afterward, use gentle cleansing, moisturiser, and diligent broad-spectrum sun protection. Do not pick flaking skin. Darkening, redness, swelling, or temporary sensitivity can occur, and pigment may need time to settle. Treatment for uneven tone is often planned as a series rather than judged immediately after one visit.

Contact the treating clinic if pain is increasing, swelling is marked, blisters develop, the area becomes hot or increasingly tender, or there is spreading discharge. Prompt review is also sensible if a treated spot changes in a way that was not expected or healing appears stalled. Urgent care is appropriate for breathing difficulty or facial swelling after any product or procedure.

Ask which diagnosis is being treated, why 532 nm is appropriate for your skin tone, what alternatives such as [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/) or [Laser Toning](/treatments/laser-and-energy/laser-toning/) would change, and how you will protect against rebound pigmentation.
