Skin Analysis and Client Consultation

Skin Analysis and Client Consultation

This domain tests intake, visual and tactile assessment, contraindication screening, Fitzpatrick typing, lesion recognition, consent, and documentation. The exam favors safe referral over diagnosis.

Core rules

  • Begin with a health history, medications, allergies, recent procedures, pregnancy status, and current home care. Ask about isotretinoin, retinoids, acids, waxing, laser, and sun exposure.
  • Classify skin type as normal, dry, oily, combination, or sensitive; note conditions such as dehydration, hyperpigmentation, and telangiectasia.
  • Use the Fitzpatrick scale to estimate sun reactivity and treatment risk; higher types have greater pigmentary response.
  • Recognize suspicious lesions using ABCDE: asymmetry, border irregularity, color variation, diameter greater than 6 mm, and evolving change. Refer; do not diagnose.
  • Obtain informed consent and document findings, products, patch tests, and recommendations.

Worked example

A client asks you to cover a new dark, irregular mole on the cheek with makeup. Inspect without diagnosing, note the ABCDE features, and refer to a dermatologist before cosmetic camouflage. Document the referral and avoid commenting that it is benign. Reasoning: estheticians may recognize suspicious lesions but cannot diagnose skin cancer; referral is the safe standard.

Traps

  • Calling a lesion 'just a mole' or 'nothing serious' exceeds scope.
  • Missing recent isotretinoin or retinoid use increases treatment risk.
  • Testing products on the hand does not predict facial allergy.
  • Failing to document a patch test or refusal weakens risk management.
