What should you know about YAG pico laser?

Pico devices emit pulses measured in picoseconds. The rapid delivery can create a photoacoustic effect that breaks pigment into smaller particles, while the clinician aims to limit unnecessary heat. It may be considered for Sun Spots, selected Melasma, or Post-Inflammatory Hyperpigmentation, but not every dark mark should be treated before its cause is clear.

After a session, mild redness, swelling, tenderness, dryness, or temporary pigment change may occur. Some people develop darker or lighter areas after inflammation, particularly when the skin is pigment-prone. Improvement can be gradual and depends on the target, wavelength, settings, and ongoing triggers.

Arrange an examination for a new, changing, bleeding, or unusual lesion before cosmetic treatment. Share your history of tanning, eczema, cold sores, keloids, medicines, and previous procedures. Use the prescribed sun protection and gentle skin care, avoid picking, and pause irritating products as directed. A clinician may compare Pico treatment with IPL Photofacial or Laser Toning, depending on whether the concern is pigment, redness, or overall tone. Take a clear baseline photograph for comparison under similar lighting.

Contact the provider about blistering, severe or increasing pain, spreading redness, pus, or swelling that affects the eyes. Seek medical review for a treated spot that continues to change or cannot be confidently identified. Do not use another light treatment on a reaction until the skin has been assessed.
