Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to apply an understanding of the composition and function of normal skin in promoting and enhancing skin care in the application of beauty services and advising on home-care products.

This unit requires the operator to demonstrate in their practice an understanding of skin biology as it applies to beauty treatments and in the promotion of healthy skin through provision of skin care advice. Knowledge of relevant legislation and workplace policies and procedures, particularly in regard to safety and hygiene, is also required.

Application of the Unit

This unit applies to beauty therapists exercising judgement in planning and selecting appropriate products, services, equipment and techniques.

Licensing/Regulatory Information

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.

3.4 Apply relevant principles of skin biology in provision of skin care and service advice. 

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

The following skills must be assessed as part of this unit:

  • technical skills to:
  • respond to possible skin damage situations
  • identify client characteristics and recommend services
  • literacy skills to source, read and apply relevant information on skin biology
  • communication skills to respond to questions and provide information, advice and reassurance to clients on skin care and beauty services.

Required knowledge 

The following knowledge must be assessed as part of this unit:

  • provision of relevant health and hygiene regulations and requirements and skin penetration legislation
  • relevant occupational health and safety regulations and requirements
  • principles of skin biology as they relate to beauty treatments
  • workplace policies and procedures in regard to beauty treatments
  • skin biology in relation to beauty treatments and procedures
  • effects of intense pulsed light (IPL) and laser hair removal on the skin.

Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the following is essential:

  • applying knowledge of:
  • main functions and role of skin
  • structure, function, distribution and development of glands of skin
  • skin colour and reaction to light and implications for beauty industry
  • role of the skin in homeostasis and thermoregulation
  • applying a range of beauty treatments, using a variety of techniques and procedures involving skin care
  • accurately and legibly recording relevant data.

Context of and specific resources for assessment 

Assessment must ensure:

  • that competency is consistently demonstrated over a period of time and observed by the assessor or the technical expert working in partnership with the assessor as described in the Assessment Guidelines
  • that competency is demonstrated in the workplace or a simulated workplace environment in a range of real work situations which may include client interruptions and involvement in other related activities normally expected in the workplace.

Assessment must ensure access to:

  • text and online resources
  • relevant workplace documentation including:
  • manufacturer's equipment instructions
  • product instructions
  • manufacturer safety data sheets
  • workplace policies and procedures manuals, including workplace services and prices
  • a range of clients with different skin and hair characteristics and treatment requirements.

For further guidance on the use of an appropriate simulated environment, refer to the Assessment Guidelines in this Training Package.

Methods of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • applying principles of skin biology in client analysis
  • completing client skin analysis and treatment plans
  • providing skin treatment and care advice for a range of beauty treatments
  • third-party reports from technical experts
  • written and oral questioning appropriate to the language and literacy level of the learner, to assess knowledge and understanding of composition and structure of normal skin
  • completion self-paced learning materials, including personal reflection and feedback from the trainer or supervisor.
