What causes uneven skin tone?

Skin colour changes when pigment production or pigment distribution differs between nearby areas. Ultraviolet exposure can deepen existing marks and contribute to sun spots and photoaging. Melasma can create symmetrical brown or grey-brown areas, often on the face, and may be influenced by hormones and light. After acne, eczema, burns, or a cosmetic procedure, inflammation can leave darker or lighter areas called post-inflammatory pigment change.

The pattern matters. Gradual facial patches, isolated spots, marks after a rash, and widespread blotchiness point toward different explanations. A clinician may examine the skin in natural light and ask about sun exposure, pregnancy or hormonal medicines, skincare products, and recent irritation.

Use broad-spectrum sun protection and protective clothing, because ultraviolet and visible light can deepen several pigment conditions. Keep skincare gentle and stop products that sting or cause persistent redness. Avoid picking spots and pause aggressive exfoliation while the skin is irritated. Once the cause is clear, a clinician may discuss prescription pigment treatment or procedures such as an IPL photofacial, picosecond laser treatment, or chemical peel. These options are not interchangeable and can worsen pigment if used at the wrong time or setting.

Book an assessment for a new, rapidly changing, bleeding, crusting, painful, or persistently itchy pigmented area. Seek advice when colour change follows a treatment, spreads beyond the original rash, or does not improve after removing an irritant. An examination is also useful when facial pigmentation affects confidence or when you are unsure whether the change is a sun spot, melasma, or post-inflammatory pigment.

Ask what pattern of pigment change is present, which triggers may be maintaining it, what sun protection is appropriate, and whether a topical treatment or procedure is suitable for your skin.
