Hyperpigmentation refers to the darkening of certain areas of the skin due to an overproduction of melanin, the pigment responsible for skin color. It can manifest in various forms, including age spots, sunspots, melasma, post-inflammatory hyperpigmentation (PIH), and freckles. Common causes of hyperpigmentation include: 1. Sun Exposure: UV radiation from the sun stimulates melanin production, leading to the formation of sunspots and uneven skin tone. 2. Hormonal Factors: Hormonal changes during pregnancy (melasma) or due to certain medications can trigger hyperpigmentation. 3. Acne Scarring: Post-inflammatory hyperpigmentation can occur after acne breakouts, leaving behind dark spots. 4. Skin Injuries: Burns, cuts, or skin inflammation can cause pigmentation changes as the skin heals. Treatments available at Dr Kora Aesthetics for skin pigmentation
