AACDS Unit 1.1 Tutorial Activity Workbook Part B: Light Therapies

This workbook is a comprehensive tutorial activity guide for students studying the Advanced Diploma of Cosmetic Dermal Science, focusing on light-based therapies and IPL/Laser safety. It comprises eight activities covering topics such as absorption coefficients, laser and light physics, IPL permanent hair reduction, Fitzpatrick skin classification, photo rejuvenation, infrared, radiofrequency, and LED technology, mock incident reports, and IPL/Laser safety protocols. The workbook includes questions, case studies, and practical exercises to reinforce learning and prepare students for examinations. The activities assess understanding of key concepts, including chromophore targeting, treatment contraindications, and safety measures. Students are prompted to analyze scenarios, complete tables, and create incident reports, demonstrating their ability to apply theoretical knowledge to real-world situations within the cosmetic dermal science field. The workbook emphasizes the importance of patient safety, appropriate treatment protocols, and effective communication. The student is required to submit the completed workbook to their assessor prior to completing the part B exam.

Please read carefully through your Internal Audit for Cosmetic Medical Practices and Beauty Clinics with Intense Pulsed
light and /or class 3B and 4 Laser.
This self-assessment is a summary of the role of the IPL/Laser Safety Officer. It will also serve as a checklist to
help you monitor risk assessment and management procedures associated with IPL and Laser.
If you are currently working with IPL or Laser, please use the audit to conduct a risk assessment and
management plan. If you are not currently working with IPL or Laser, please keep this audit document on file
for you to use in your pending role as IPL/Laser Safety Officer.
Tutorial Activity – Incident Reports Yes No
Using the information from Clinical Study 9 (Vesiculobullus Eruption from Intense Pulsed Light Treatment),
write a mock incident report on the following page (extracted from page 11 of your Internal Audit for Cosmetic
Medical Practices and Beauty Clinics with Intense Pulsed light and /or class 3B and 4 Laser).
Patient/client name: DOB: 01.01.1234
Please specify the type of treatment and the particular IPL or LASER used in which the incident occurred.
Please provide the details of the incident.

Tutorial Activity 7 – Incident Reports (cont.)
Dealing with an adverse incident in the medical or beauty practice can be a sensitive issue. The staff member
associated with the incident may feel ashamed and concerned about loss of credibility or even losing their job.
This is not the type of environment conducive to proper risk assessment and management. Staff must feel
comfortable about discussing adverse incidents without fear of criticism.
a) Explain how you would discuss the incident with other staff members Yes No
