The disclosed technology can be used to enhance the brightness of a multi-wavelength light source incorporated within a dermatologic system to thereby increase its efficiency and reduce the power and filtering requirements of the system resulting in an overall reduction in the size and cost of the system. The disclosed technology can enhance a users experience with the dermatologic system by reducing the users pain sensation when using the system during a dermatologic treatment and/or facilitating the movement of the system across a skin surface under treatment.
