IPL or laser for dark spots: what to know first

Dark patches are a symptom, not one single condition. Melasma can form recurring facial patches; post-inflammatory hyperpigmentation can follow acne, eczema, injury, or a procedure; and sun spots are linked with cumulative ultraviolet exposure. Tinea versicolor is a superficial yeast-related condition that can alter skin colour and needs a different approach. Because these causes behave differently, a flash of light may be unsuitable or may worsen pigment in some people.

IPL uses a broad range of light, while a laser delivers a more specific wavelength or pulse pattern. Neither should be used to erase an undiagnosed changing spot. A clinician may examine the area, ask about onset and triggers, and review medicines or previous reactions before discussing treatment.

Arrange an assessment if a patch is new, spreading, itchy, scaly, inflamed, or repeatedly returning. Share your skin tone, recent sun exposure, history of dark marks after irritation, pregnancy or hormonal changes, and previous procedures. Treatment may involve sun protection and addressing the cause first. Depending on the diagnosis, options can include a chemical peel, a skin brightening treatment, or a picosecond laser treatment; selection should be individualized rather than based on the darkest-looking patch.

Seek prompt assessment for a spot that changes in size, shape, colour, or texture, bleeds, crusts, becomes persistently painful, or differs clearly from nearby marks. After IPL or laser, contact the provider for blistering, severe pain, worsening swelling, spreading redness, or pronounced lightening or darkening. Urgent help is warranted for eye pain or vision changes.

Ask what diagnosis is being treated, why IPL or a particular laser is suitable, how your skin tone changes the plan, and what alternatives exist. Confirm sun precautions, expected recovery, warning signs, and whether a test area is appropriate.
