Hyperpigmentation: What Causes It and How to Treat It Effectively

Dark spots, uneven skin tone, post-breakout marks, sun damage — hyperpigmentation is one of the most common skin concerns our clients bring to us, and one of the most misunderstood. The good news: with the right treatment approach, it is also one of the most treatable.

What is hyperpigmentation?

Hyperpigmentation is the overproduction of melanin — the pigment that gives skin its colour — in specific areas. When melanocytes are triggered by inflammation, UV exposure, or hormonal changes, they produce melanin in excess, resulting in patches or spots that appear darker than the surrounding skin.

The most common types

• Sun damage (solar lentigines): Flat brown spots caused by cumulative UV exposure, typically appearing on the face, hands, chest, and shoulders from your 30s onwards.

• Post-inflammatory hyperpigmentation (PIH): Dark marks left after acne, trauma, or skin inflammation. More persistent in deeper skin tones.

• Melasma: Symmetrical, blotchy darkening triggered by hormonal fluctuations — pregnancy, the pill, or perimenopause. Often appears on the cheeks, forehead, and upper lip.

Why SPF is non-negotiable

UV exposure is the primary driver of hyperpigmentation — not just its initial development, but its persistence. Even on overcast days, UV rays reach the skin and stimulate melanocyte activity. Without daily broad-spectrum SPF 50+, any pigmentation treatment will be undermined. SPF is foundational, not optional.

Professional treatments that clear pigmentation

Over-the-counter brightening products can provide modest improvement for mild pigmentation, but for meaningful clearance of established sun damage, PIH, or melasma, professional treatment is required. At St James Aesthetics, we use a targeted approach:

• Skin resurfacing: Accelerates cell turnover to bring pigmented cells to the surface and shed them rapidly, revealing fresher, more even skin beneath.

• Lactic acid peels: Gentle but effective chemical exfoliation that addresses surface pigmentation while also supporting hydration and skin texture.

• Microdermabrasion: Physical resurfacing that removes the outermost layer of dead, pigmented cells and stimulates cell renewal.

The right treatment depends on your pigmentation type, skin tone, and history. Melasma in particular requires a careful approach as aggressive treatments can sometimes worsen it. A thorough skin consultation is always the starting point at St James Aesthetics.

Book a skin consultation at our Camberwell, Moonee Ponds, or Geelong clinic and let our team assess your pigmentation and design a treatment plan that actually works.
