Hyper pigmentation is a prevalent skin disorder that has numerous causes and often challenging to treat. The different types of hyper pigmentation will vary in each individual and may depend on genetics, skin color and life style. Some of the causes include:
- Post-inflammatory hyper-pigmentation – this is commonly found in acneic conditions, dark skin individuals, and post-operative procedures. It generally occurs after a wound or in response to an injury.
- Ethnicity or darker skin – which includes Hispanic, American and Eastern Indian, Asian, African and Middle Eastern are very susceptible to hyper-pigmentation. These particular skin types have a tendency to be hyper active within the melanocytes cells and production of the tyrosine enzyme or in other words, sensitivity can lead to hyper pigmentation.
- Melasma, also referred to as Chloasma, symptoms include dark irregular patches commonly found on the cheeks, nose, lips and forearms which usually develops over time. It’s generally more common in darker skin, lighter skin can be affected especially from intense sun exposure. Hormones and medication can also trigger Melasma.
- Sun damage – or over exposure to the sun can cause solar lentigines or freckles. They are generally found on the face,
shoulders, neck, back, arms and hands and can affect all skin types.
Prevention and Treating…
In all cases sun protection must be considered to protect avoiding further damage. Studies have shown that diet can contribute to treating post-inflammatory hyper pigmentation by eliminating white wheat and sugar. For darker skin, some ingredients that may help include, kojic acid, mandelic acid, hydroquinone, and tretinoin (beware of sun exposure when using).
Other procedures for treating hyper-pigmentation may include chemical peels, Photo-Rejuvenation (IPL, BBL), laser resurfacing or Profractional treatments.
