Hi Tan SP,
I fully agree t hat you most likely have post-inflammatory hyperpigmentation (PIH), which commonly occurs after inflammation or injury to the skin. This condition is more common in darker skin types.
Some common precipitating factors include acne or trauma, but may also be caused by previous laser therapy, dermabrasion or chemical peels. It can affect patients of all ages and gender, but is more severe usually in darker skinned individuals.
Depending on the underlying cause, the pigment may be deposited in the epidermis (superficial layer of the skin) or dermis (deeper layer of the skin).
PIH usually resolves over a few months, although dermal hyperpigmentation may not improve significantly with time.
Treatment options include:
1. Topical treatment with medications containing hydroquinone, a skin bleaching agent, or retinoids such as Triluma. These options typically require weeks to work.
2. Chemical peels containing alpha hydroxy acid or beta hydroxy acid. A series of superficial peels may be required, as deeper peels themselves MAY result in hyperpigmentation
3. Lasers, utilising Q switched or fractional resurfacing modalities
Your physician will be able to diagnose your PIH and advise on treatment options!
