Hyperpigmentation, which is caused by an increase in the skin's melanin content, is one of the most common skin concerns seen by skin care professionals. This condition is most often caused by sun exposure; inflammation; hormonal changes, such as pregnancy; certain medical conditions, like Addison's disease; and various drugs, such as certain antibiotics. Hypopigmentation lies on the other side of the pigmentation coin and is the result of a lack of melanin production in the skin. The most recognizable forms of hypopigmentation include vitiligo and albinism, although the most common cause of the condition is damage or trauma to the skin, such as burns, blisters, and scrapes. Hypopigmentation can also be caused by improperly administered resurfacing treatments, such as IPL, laser, and chemical peels. Pigmentation concerns, like many other skin conditions, can have a negative emotional impact on sufferers. These conditions, especially very severe forms of them, can lower self-esteem, cause undue stress, and impact the client's productivity and quality of life. As a result, professionals can suggest that clients engage in spa treatments that are geared toward stress relief and practice stress management skills at home.Want to read more?
