Patch Test

Method

1. Apply small amount behind ear or inner arm
2. Wait 24-48 hours
3. Check for redness, itching, breakout
4. If OK, proceed full face

Always patch test new product especially:

• Retinoid
• Acid
• Strong serum
• Premium products (expensive to waste)

Pro Tips

1. Slow Routine Changes:

Add 1 new product/2 weeks. Easier identify trigger if reaction.

2. Keep Product Diary:

Note reactions + improvements. Helps narrow down sensitivities.

3. Consult Dermatologist:

Persistent sensitivity → da liễu test + diagnosis. Possible underlying condition.

4. Stress Management:

Sleep, exercise, meditation reduce skin sensitivity.

5. Diet Considerations:

Anti-inflammatory diet (omega-3, vegetables) supports skin.
