Avoid reactions and wasted money with strategic testing.
Patch Testing Protocol:
- Where: Behind ear or inner forearm
- How: Apply small amount twice daily for 5-7 days
- What to Watch For: Redness, itching, burning, bumps
- If Clear: Test on small area of face (jawline or temple)
The One-at-a-Time Rule:
- Introduce only ONE new product every 2-4 weeks
- This helps identify what works (or causes issues)
- Start with most important product first (often treatment serum or moisturizer)
Realistic Timeline:
- Hydration: Improvement in days
- Texture: 2-4 weeks
- Acne: 4-8 weeks
- Hyperpigmentation: 8-12+ weeks
- Anti-aging: 3-6 months for visible results
