Home-Use Devices: An Overview and Regulatory Aspects

Media exposure of light-based technologies and medical and scientific validation has led to the introduction of miniaturized, low-cost devices for home use by the consumer (HUDs). These scaled-down lasers and intense pulsed light appliances produce measurable results in hair removal, hair growth stimulation, acne and psoriasis management, and skin rejuvenation at home, both medically directed and consumerled. This chapter reviews major brands of hair reduction and skin rejuvenation devices that have entered the market, their mode of action (both thermal and non-thermal), and their clinical efficacy and safety. Reported side effects and adverse incidents are examined, and reasons for products being withdrawn from the market are explained. The development of international standards and regulatory changes intended to accommodate this new generation of home-use appliances is described, and their impact on professional service providers and how they are being integrated as potential "companion" products alongside professional consultation and treatments is discussed.
