4.3.2. Contraindications — When to Modify or Decline Service

💡 First Principle: Contraindications exist on a spectrum. An absolute contraindication means no service — the risk of harm is too great to proceed regardless of modification. A relative contraindication means the service may proceed with appropriate modifications — a different product, technique, or treatment area.

Correctly distinguishing absolute from relative contraindications is a high-frequency exam skill. The key question is: can the risk be managed by adapting the service, or does the condition require medical clearance before esthetics treatment is appropriate?

Absolute contraindications (decline service):

• Active infectious skin conditions (impetigo, herpes outbreak, ringworm in treatment area)
• Open wounds, sores, or recent surgery in the treatment area
• Undiagnosed skin lesions or growths (refer to physician)
• Severe systemic illness or fever
• Known allergy to a product with no safe alternative
• Clients on Accutane within 6 months (for waxing and chemical treatments)

Relative contraindications (modify service):

• Mild acne — avoid inflamed areas, proceed with gentle techniques elsewhere
• Rosacea — proceed with no heat, no steam, gentle products only
• Sensitive skin — use fragrance-free, minimal-ingredient products; skip aggressive exfoliation
• Recent sun exposure — avoid chemical exfoliants and aggressive treatments
• Topical retinoids — reduce exfoliation intensity; check last use date

The referral responsibility: When you decline a service, the professional obligation doesn't end with "no." You should explain why the service cannot be performed at this time, suggest they consult their physician, and offer to provide service after medical clearance if appropriate.

✅ Best Practice: Document all consultation findings, your decision, and any referral recommendations. If a client declines a referral and insists on service, document that refusal as well. Your documentation protects you professionally and legally.

⚠️ Exam Trap: The exam frequently presents a client who is frustrated that service is being declined and offers a waiver or insists their condition is mild. The correct answer remains: decline and refer. Client insistence does not change a contraindication into a safe situation.

Reflection Question: A client mentions they started using a prescription retinoid three nights ago and wants their normal facial including microdermabrasion. Classify this as an absolute or relative contraindication, and describe what the appropriate professional response is.
