The evidence guide describes the underpinning knowledge and skills that must be demonstrated to prove competence. It is essential for assessment and must be read in conjunction with the performance criteria, the range statement and the assessment guidelines of the relevant Training Package. Overview of assessment A person who demonstrates competency in this standard must be able to identify, describe and apply skin biology, including the anatomy of human skin and hair, to the performance of beauty treatments. Knowledge and understanding of the principles of skin biology as they relate to beauty treatments must be demonstrated.
Critical aspects of evidence required to demonstrate competency in this unit
Knowledge and consistent application of relevant workplace policies and procedures.
Knowledge and consistent application of Federal, State and local health and hygiene requirements/regulations and skin penetration legislation.
Knowledge and consistent application of safe work practices and the safe use of products and equipment including the use of preventative measures, according to manufacturer safety manuals and Occupational Health and Safety regulations/requirements.
Knowledge and consistent application of the principles of skin biology as they apply to beauty treatments, including:
main functions and role of the skin
structure, function, distribution and development of the glands of the skin
skin colour and its implications to the beauty industry
role of the skin in homeostasis and thermoregulation
role of skin as a sense organ
main functions and role of hair
gross structural features of the pilobaceous unit
structural and cellular features of hair and hair follicles
process of hair growth and the hair growth cycle
effects of beauty treatments on hair and skin
provision of aftercare service and advice.
Knowledge and skill in the application of a variety of beauty treatments, using a variety of techniques/procedures involving skin care.
Accurately and legibly recording relevant data.
Context of assessment
For valid and reliable assessment of this unit, competency should be consistently demonstrated over a period of time and observed by the assessor and/or the technical expert working in partnership with the assessor. The technical expert may include the beauty therapist and/or a skin biology specialist and may be in a simulated environment.
Competency should be demonstrated in the workplace or a simulated workplace environment in a range of situations which may include client interruptions and involvement in other related activities normally expected in the workplace. For further guidance on the use of an appropriate simulated environment, refer to page 32 of the Assessment Guidelines in this Training Package.
Relationship to other units
This unit is a co-requisite for a range of beauty units. It requires an assessment outcome which includes evidence of the application of knowledge of skin biology to the performance of one or more beauty treatments.
This unit must therefore be assessed in conjunction with one or more of the following related units:
WRBBS407B Provide body treatments
WRBBS509A Plan the spa program
WRBBS510A Provide the spa program
WRBBS511A Apply aromatic plant oil chemistry to beauty treatments
WRBBS512A Blend a range of aromatic plant oils for beauty treatments
WRBBS513A Use reflexology relaxation techniques in beauty treatments
WRBFS305B Provide lash and brow treatments
WRBFS406B Provide facial treatments
WRBFS407B Provide advanced facial treatments
WRBSS302B Provide temporary epilation and bleaching treatments
WRBSS503B Provide permanent epilation
WRBSS504B Perform diathermy service
WRBSS505B Design and perform cosmetic tattooing/micropigmentation procedures
WRBSS506A Provide upper body piercing
Method of assessment
The following assessment methods are suggested:
observation of the learner performing a range of tasks in an actual or simulated work environment, over sufficient time to demonstrate his/her handling of a range of contingencies. Tasks may include:
