How long does picosecond laser take to work for freckles?

The laser targets melanin in freckled skin. After treatment, freckles may temporarily darken or develop fine crusts, then shed as the surface recovers. Pigment clearance continues after the appointment, so early photographs can be misleading. Freckles are strongly influenced by ultraviolet exposure, and new or darker freckles can appear even after an initially good response.

The clinician will consider your natural skin tone, the number and size of freckles, recent sun exposure, and whether another condition resembles freckles. A diagnosis matters before any pigment treatment.

Protect the treated skin from sunlight with clothing and the sun-protection plan recommended by your clinician. Keep hands off crusts, pause irritating products until the skin has recovered, and follow instructions about cleansing and makeup. Keep scheduled reviews; treatment settings or the interval between sessions may need adjusting according to healing and pigment response.

Tell the clinic about increasing pain, spreading redness, pus, severe swelling, or blistering. Arrange a medical review for a freckle that changes independently of treatment, bleeds, develops several colours, or has a new uneven edge.

Ask when to take comparison photographs, how long redness or darkening may last, whether a test area is advisable, and which products to avoid while healing. Ask how to reduce the chance of pigment returning with sun exposure.
