scattered off a material most of it is scattered in its original wavelength but a small amount is scattered in a different wavelength (2013). A microscope is used to collect the light giving a Raman spectrum‚ which gives a characteristic vibrational fingerprint (2013). This can then be compared to various types of lipsticks (2013). Currently more research is being conducted into applying the same method on other types of cosmetic evidence‚ such as eyeliners‚ and skin creams (2013). This recent advancement
