WHAT IS HYPERPIGMENTATION
The skin gets its color from a pigment called melanin. Skin pigmentation disorders include hyperpigmentation (dark skin patches on the skin) or hypopigmentation (light skin patches). Hyperpigmentation normally occurs when there’s an increased secretion of melanin, which is produced by special skin cells, melanocytes, in the lower epidermis.
Melasma (tan or brown patches)
Hyperpigmentation typically occurs as a result of excessive sun exposure. In other words, to protect the skin from this, melanin absorbs the harmful ultraviolet rays form the sun. But, while doing so, it may trigger appearance of freckles and age spots (liver spots). It may even make other darkened skin patches become even more prominent. This skin pigmentation disorder is more common in people with darker Asian, Mediterranean or African skin tones, especially after too much sun exposure.
CAUSES OF HYPERPIGMENTATION INCLUDE:
- PIH (Post Inflammatory Hyperpigmentation),
- Estrogen (HRT),
- Continual sun exposure,
- Razor bumps,
- Severe sunburn,
- Chemical irritations,
- Abrasive scrubs,
- Some medications,
- Chicken pox,
- Insect Bites,
- Skin trauma,
- Surgical procedures,
- Perfumes applied on sun-exposed areas.
*** It’s the harmful UV rays that affect melanin function thus triggering temporary or permanent skin discoloration including freckles, age and sun spots. Although these are most obvious on the face, they can actually appear on any part of the body that’s been sun-exposed.
*** Skin trauma such as scars, including surgery scars,
