TUTORIAL ACTIVITY 1 - ABSORPTION COEFFICIENT GRAPHAnswer the following question using the Coefficient graph below:Question 1 Yes NoAnswer true or false to the following statements:Statement 500nm 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 2 Yes NoDoes a Ruby Laser treat blood vessels?Ruby laser is used for the treatment of skin related problems like age spots, light pulses, hair removal, it can not treat the blood vessels.Question 3 Yes NoAn IPL handpiece that emits 500nm to 670nm would target which chromophores?Melanin is considered as primary chromophores. Laser will directly target melanin. Assessor’s comments AUSTRALASIAN ACADEMY OF COSMETIC DERMAL SCIENCE ©2015Version 1.0 3Data/Curriculum/Unit 1.1 / Assessments/Workbooks/Workbook Part B
Question 4 Yes NoWithin 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 5 Yes NoBriefly explain why longer wavelengths are used for hair reduction?Longer wavelengths are the largest wavelengths that are used, because these can treat the widest range of skins and hair types. 755Nm wavelength is used to treat thin hair, and light skin. 1100Nm wavelength is used for thick hair and dark skin.Question 6 Yes NoWater absorption will decease or enhance tissue penetration?Our skin is having almost 70% of water, which is present in the tissues. Water penetration will enhance the skin penetration because the moisture content will be more and it will be very easy for the laser of 700nm to penetrate the skin.Question 7 Yes NoIndicate at which nanometer range are the various lights covered.VisibleUltravioletInfrared400-800nm100-400nm800nm-1mmQuestion 8 Yes NoCan IPL cause skin cancer? (Please explain your answer, referring to the Ionising and Non-Ionising Radiation handout).IPL is not a radiation therapy. It is only the lights of different wavelengths, which are used for the treatment of hair removal or other disease. So it will not cause skin cancer.Question 9 Yes NoWhich of the following chromophores has the shortest TRT and therefore, would require a shorter pulse width?HairMedium sized vesselMelanin (melanosome)Question 10 Yes NoIn 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 dark side of skin. These skins are having higher concentration of melanin, which means greater risk of damage, if the laser setting is not correct. That can cause permanent damage like hyperpigmentation, burning or scarring.Assessor’s comments AUSTRALASIAN ACADEMY OF COSMETIC DERMAL SCIENCE ©2015Version 1.0 4Data/Curriculum/Unit 1.1 / Assessments/Workbooks/Workbook Part B
