Available in PDF, EPUB and Kindle. Book excerpt: As skin care professionals, we are frequently presented with clients' skin concerns relating to hyperpigmentation disorders, or the uneven distribution of visible melanin in the skin. The source of this spotty disarray can be a combination of factors, with sun exposure being universally recognized as a primary cause. Evidence of adolescent inflammatory acne may be present decades later, compounding damage from new breakouts at the onset of mid-life. In men and women, hormonal fluctuations, smoking, and a history of excessive/aggressive treatments are known to trigger the production of melanin. The biomedical research of skin mechanisms that create melanin have allowed a discerning look into the topical agents currently in the professional skin care market, used across skin types and age ranges.
