What should you know about hyperpigmented spots on skin?

Dark marks may appear after pimples, folliculitis, shaving irritation, or a rash has settled. This is called post-inflammatory hyperpigmentation. Sunlight can deepen existing marks and contribute to uneven tone. Facial pigmentation may also occur with hormonal changes or skin conditions such as acne, rosacea, or perioral dermatitis. The colour can range from tan to brown or grey, and the surface may be flat even when the original trigger was raised or inflamed.

The appearance alone cannot identify the cause. A clinician considers the spot’s onset, location, borders, texture, symptoms, medicines, and pattern of change.

Use broad-spectrum sun protection on exposed skin, seek shade, and avoid picking or scrubbing marks. A gentle cleanser and moisturiser help reduce irritation while active acne or shaving bumps are addressed. Introduce one pigment-focused product at a time because stinging and peeling can worsen discoloration. A dermatologist may discuss prescription creams, procedures, or treatment of the underlying trigger after examining your skin. Read about Acne, Folliculitis, or LED Light Therapy when those topics match your symptoms.

Arrange a skin assessment for a new or changing dark spot, especially if it develops irregular edges, several colours, a firm or rough surface, repeated bleeding, persistent crusting, or ongoing pain. Seek prompt care when a mark changes quickly or does not behave like your other spots. A clinician can decide whether examination alone is enough or whether testing is needed.

Could this be post-inflammatory pigmentation, a medication effect, or another condition? Which ingredients should I avoid if my skin is sensitive? What sun-protection routine fits my daily exposure? Should a changing spot be examined or monitored?
