What should you know about laser treatment for skin brightening?

Dark patches can result from melasma, post-inflammatory hyperpigmentation after acne or injury, sun exposure, medicines, or another skin condition. A laser may break up or remove pigment in selected layers, but it does not correct every cause. Melasma in particular can return or become more noticeable after irritation or heat.

Skin tone, pigment depth, recent tanning, and the treatment area affect the risk of prolonged redness or darker or lighter patches. A clinician may recommend a topical routine before or after laser, such as a carefully selected brightening ingredient. The goal should be more even tone while preserving the skin barrier, not changing your natural skin colour.

Ask for the cause of the pigmentation to be assessed before treatment. Mention pregnancy, hormonal medicines, acne, eczema, recent sun exposure, cold sores, previous pigment changes, and all skincare products. Avoid tanning and follow the prescribed plan; daily broad-spectrum sunscreen, shade, and physical protection help limit re-darkening.

Cysteamine or kojic acid may be discussed for some pigment concerns, but suitability depends on the diagnosis and skin sensitivity. Pause irritating products only as directed. After laser, use gentle cleansing and moisturising, avoid picking or scrubbing, and report worsening pigment or prolonged inflammation.

Arrange prompt assessment for a new dark patch that changes quickly, bleeds, crusts, becomes painful, or has an irregular appearance. After treatment, seek care for blistering, severe pain, spreading swelling, pus, fever, or pigment change that is worsening. Cosmetic brightening should not delay evaluation of a suspicious lesion.

Ask what is causing the uneven tone, whether laser is appropriate for your skin type, how heat and pigment changes will be managed, and what non-laser options may help. Ask about preparation, aftercare, sun protection, signs of infection, and the plan if pigmentation returns.
