Noninvasive Radio Frequency for Skin Tightening and Body Contouring Consumer demand for noninvasive methods for skin tightening, wrinkle reduction, body contouring, and cellulite reduction is continuously growing. Patients want to look better and younger, in part due to the fear of being replaced by younger colleagues in a competitive job market. As less time for…
Selective photothermolysis (Part 2) Melanin absorbs across a wide spectrum of wave-lengths. Eumelanin, the primary chromophore in the epi-dermis and darkly pigmented hair follicles, has a broad absorption spectrum spanning from ultraviolet light to the near-infrared region. Eumelanin is the chromophore targeted in lentigo simplex. It is also the target in laser hair removal with…
Selective photothermolysis (part 1) SP relies on fundamental choices being made correctly – wavelength, pulse duration, fluence, exposure spot size, and use of skin cooling. First, a wavelength (or, with IPLs, a range of wavelengths) must be used that is preferentially absorbed by the intended ‘target’ structures such as hair follicles, microvessels, tattoo inks, or…
Light interactions with skin Photons can be absorbed (giving up their energy to matter) or scattered (changing their direction of travel). Light that is scattered back from skin is called reflectance. For a given skin layer, light that passes through it is called transmittance. Scattering is inversely wavelength depen-dent, such that shorter wavelengths are scattered…
Facial Aging-Related Problems Facial aging can result from a variety of causes. Some factors are intrinsic and uncontrollable; others are extrinsic and controllable to a certain degree. All human beings appear to age along a common progression; however, differences related to lifestyle, gender, and ethnicity can be seen. For example, it is noted that the…
Changes in the Skin The facial skin is continually exposed to a variety of external conditions, such as wind, cold, heat, and ultraviolet radiation. The last factor is the principal agent causing extrinsic aging of the skin, with effects that are significant enough to warrant the term “photoaging.” This exposure extends throughout an individual’s life,…
Laser and Light Light is a fundamental form of energy with numerous medical applications. At the quantum level, light is composed of packets of energy, known as photons. Each photon carries a discrete amount of energy. Light is also an electromagnetic wave. The electromagnetic spectrum extends from low frequency radio waves to ultra-highenergy gamma rays.…
