Post – inflammatory hyperpigmentation (PIH) is skin pigmentation that is seen after injury to the skin. It is commonly seen in individuals with dark skin tone as any slightest injury will trigger the numerous pigment producing cells in the skin to produce even more pigment. In dark skin persons, the colour may be more intense and lasts for a longer period of time. The pigmentation is confined to the areas of injury
Causes of post-inflammatory hyperpigmentation
- After skin injury or irritation
- After an underlying skin condition has healed
- After skin procedures like chemical peels, surgery, laser treatments
- After taking some medication
Treatment of Post-inflammatory hyperpigmentation
- Prescription creams and oral medication
- Laser treatments
If you are prone to post injury pigmentation, or PIH, let your dermatologist know before you undertake any aesthetic skin procedures
Dark eye rings are seen in children and adults and are often due to a combination of factors.
Causes of dark eye rings
- Congestion of vessels below the skin
- Pigmentation in the skin
- Post eczema (PIH)
- Hollowness due to aging. As one grows older the eye socket gets larger and the lower eyelid skin sags and this accentuates the dark rings
- Genetic predisposition. In Asians dark eye rings may appear at an early age and they get darker with age
Treatment of dark eye rings
- Treatment depends on the various causes
- Prescription creams
- Light and laser treatment
- Sometimes dermal fillers will improve the sunken eyelids and as light reflects from the skin the dark eye rings appear lighter
