What should you know about green light therapy for hyperpigmentation?

Hyperpigmentation means an area looks darker because skin pigment has increased or become more noticeable. It can follow inflammation, irritation, injury, hormonal change, or sun exposure. Green light is visible light delivered by a device; it does not reveal which cause is present, and it may not be the right option for every patch. Dark Patches On Skin can describe several different findings, including ones that should be examined rather than treated cosmetically.

Treatment aims often include reducing contrast and preventing further darkening. Improvement can be gradual, and irritation from an unsuitable procedure may make colour changes more noticeable, especially in skin that marks easily.

Have the patch assessed before booking a course. Share its onset, any itching or scaling, recent spots, pregnancy or hormonal treatment, and products that have irritated it. Daily broad-spectrum sun protection and gentle skincare help limit ongoing pigment stimulation. Do not layer unplanned light sessions with peels or strong bleaching products.

Depending on the cause and skin type, a clinician may discuss Skin Brightening Treatment, Chemical Peel, IPL Photofacial, Picosecond Laser Treatment, or Hydroquinone Treatment. Each has different preparation, aftercare, and risks of irritation, so the treatment should be selected for the diagnosis rather than the colour of a device.

Seek a dermatology assessment for a patch that is new, rapidly changing, irregular, bleeding, crusted, painful, or persistently itchy. Get advice promptly if several areas appear without a clear trigger or if a treatment causes blistering, marked swelling, or worsening colour. Avoid repeated cosmetic sessions until the skin has been reviewed.

What is causing this pigmentation? Is green light appropriate for my skin type and diagnosis? How will irritation or rebound darkening be prevented? Should I use a prescription product first? What aftercare and sun protection will I need?
