TUTORIAL ACTIVITY 1 - ABSORPTION COEFFICIENT GRAPHAnswer the following question using the Coefficient graph below:Question 1YesNoAnswer true or false to the following statements:Statement500nm is a longer wavelength than 900nm.TRUE500nm will penetrate the skin deeper than 900nmTRUEMelanin absorption will occur no matter what IPL handpiece is usedTRUEYou can target blood vessels without targeting melaninTRUEQuestion 2YesNoDoes a Ruby Laser treat blood vessels?Ruby laser is used for the treatment of skin related problems like age spots, light pulses, hair removal, itcan not treat the blood vessels.Question 3YesNoAn IPL handpiece that emits 500nm to 670nm would target which chromophores?Melanin is considered as primary chromophores. Laser will directly target melanin.Assessor’s commentsAUSTRALASIAN ACADEMY OF COSMETIC DERMAL SCIENCE ©2015Version 1.03Data/Curriculum/Unit 1.1 / Assessments/Workbooks/Workbook Part B
Question 4YesNoWithin the visible light spectrum, which colour has the greatest depth of penetration into the skin?Red light has the greatest depth of penetration into the skinQuestion 5YesNoBriefly explain why longer wavelengths are used for hair reduction?Longer wavelengths are the largest wavelengths that are used, because these can treat the widest rangeof skins and hair types. 755Nm wavelength is used to treat thin hair, and light skin. 1100Nm wavelengthis used for thick hair and dark skin.Question 6YesNoWater absorption will decease or enhance tissue penetration?Our skin is having almost 70% of water, which is present in the tissues. Water penetration will enhancethe skin penetration because the moisture content will be more and it will be very easy for the laser of700nm to penetrate the skin.Question 7YesNoIndicate at which nanometer range are the various lights covered.VisibleUltravioletInfrared400-800nm100-400nm800nm-1mmQuestion 8YesNoCan IPL cause skin cancer? (Please explain your answer, referring to the Ionising and Non-Ionising Radiationhandout).IPL is not a radiation therapy. It is only the lights of different wavelengths, which are used for thetreatment of hair removal or other disease. So it will not cause skin cancer.Question 9YesNoWhich of the following chromophores has the shortest TRT and therefore, would require a shorter pulse width?HairMedium sized vesselMelanin (melanosome)Question 10YesNoIn your own words, briefly discuss why Fitzpatrick skin types IV+ are at a greater risk of burning with IPL and laser.Fitzpatrick skin type IV+ includes asian, indians, and some africans who are having dark or a little darkside of skin. These skins are having higher concentration of melanin, which means greater risk ofdamage, if the laser setting is not correct. That can cause permanent damage like hyperpigmentation,burning or scarring.Assessor’s commentsAUSTRALASIAN ACADEMY OF COSMETIC DERMAL SCIENCE ©2015Version 1.04Data/Curriculum/Unit 1.1 / Assessments/Workbooks/Workbook Part B
