What it is

A description, not a diagnosis.

Hyperpigmentation is a term to describe darker than normal skin and not a diagnosis. It is important to get the diagnosis right before the treatment.

There is a wide differential diagnosis of hyperpigmentation, and the right treatment depends entirely on which condition is causing it and at what depth the pigment sits.

What we treat

Four categories, four approaches.

Hormonal & UV

Melasma

Melasma is a common hyperpigmentary disorder which can be triggered or worsened by sun exposure and hormonal changes. There is no cure and it often recurs after treatment, so the key to successful management is to address all underlying causes as well as preventing recurrence after the initial successful treatment. A combination of medical therapies and laser toning can improve melasma.

Post-inflammatory

Post-inflammatory hyperpigmentation (PIH)

PIH is caused by inflammation on the skin such as acne, eczema, trauma or cosmetic procedures including peels, microneedling and laser. It may fade with time over months to years, but treatments can speed up the process: laser toning, prescription cream, or iontosonophoresis combined with skin lightening ingredients to deliver the lightening actives to the deeper layers of the skin where the pigmentation tends to be found.

Superficial

Freckles & age spots (lentigines)

Freckles and age spots are more superficial pigmentation which can be removed successfully with lasers, but there is a high risk of recurrence, especially with sun exposure. Some maintenance gentle laser treatment can keep it under control for a longer duration.

Cellular

Other pigmentary conditions

Some pigmentary disorders such as naevus of Ota, ABNOM and café au lait macules are caused by an increased number of cells containing pigments rather than increased production of melanin. Topical skin lightening cream is not effective for these, and they are best treated with laser. We have various pigment lasers to target different depths and types of pigmentation.
