Prognosis
Prognosis Colloid milium lesions remain static and do not resolve. Lesions reach their peak within 3 years, after which very few new papules occur. Patient Education Genetic counseling is advisable for the rare juvenile form of colloid milium. [emedicine.medscape.com]
Etiology
Etiology The classic adult and nodular forms of colloid milium are believed to be due to excessive sun exposure, which appears to cause degeneration of elastin. [emedicine.medscape.com]

Prolonged use of hydroquinones has resulted in the development of the pigmented form of colloid milium, sometimes in association with ochronosis. [13] Epidemiology Frequency Colloid milium is rare, but more than 100 case reports are present in the world [emedicine.medscape.com]
Pathophysiology
The 4 variants are (1) an adult-onset type, (2) a nodular form (nodular colloid degeneration), [1] (3) a juvenile form, [2, 3] and (4) a pigmented form, thought to be due to excess hydroquinone use for skin bleaching. [4] Pathophysiology Colloid milium [emedicine.medscape.com]
