![]() By multiple synchronized pulsing, which are usually two to three and maximum five pulses, with delays in between, both the target and epidermis are heated by the first pulse just within the threshold limit of the epidermis, therefore the epidermis is not damaged. Longer TRT means the target takes longer time to cool to 50% of the temperature achieved. Even though the epidermis is a strong competing chromophore for smaller targets, it can be spared as long as the TRT of the target is longer than that of epidermis. The UV irradiation induced chemical changes in deoxyribonucleic acid (DNA) may be responsible for cell death and neoplastic transformation. This is made use of in removing tattoos and clearing certain pigmented lesions.Įxample of light energy causing a chemical reaction is photosynthesis in plants. Physical or mechanical tissue changes, known as photoacoustic changes occur when high energy photons are delivered in ultra short pulses of nanoseconds. Out of these, thermal changes are most useful, as in hair reduction, skin rejuvenation and in vascular lesions. However the selection of spot size also depends on the power generation of the system as well as on the depth of the chromophore from the skin surface.Ībsorbed photons can produce thermal, mechanical, or chemical changes in and around the chromophore. Therefore, larger the spot deeper is the penetration. In case of large spot, after scattering, photons hit each other and get recollected and redirect themselves in the direction of the beam thereby increasing the depth of penetration. In the tissues more scattering occurs when a small spot is used. The greater the scattering, less will be the depth of penetration, and more possibility of absorption. It, therefore, appears to act as a turbid matrix in which scattering is an approximately inverse function of wavelength (shorter wavelength, greater scattering). In the dermis, scattering has been shown to occur predominantly from inhomogeneities in structures whose size is of the order of the wavelength or slightly larger e.g. ![]() We also have beautiful Elemis gift sets and products available for purchase, you can purchase at the Killashee Spa or call us for further information.Scattering is due to lack of homogenety in the skin's structures, such as molecules, organelles, cells or larger tissue structures.
