1. Why Do Eyelash Extensions Trigger Allergies?
① Adhesive Chemicals
Common Irritants:
Formaldehyde (in 78% of low cost glues according to Journal of Cosmetic Science)
Carbon black pigment (Cause of dermatitis)
Cyanoacrylate monomers (responsible for redness is vapor)
② Lash Material Risks
Synthetic fibers: Could have trace acrylates
Mink lashes: Animal protein allergens (via the Allergy & Rhinology study)
③ Poor Application
Unsterilized Instruments → Bacterial Infection
Gluing to skin vs. lash base
2. Safety ProtocolISO 13485 Certified

3. Emergency Care for Allergic Reactions
| Symptom | Action |
|---|---|
| Mild redness/itch | Remove extensions → Apply cool compress + saline rinse |
| Swollen eyelids | Use 1% hydrocortisone cream (avoid eyes) → See ophthalmologist |
| Blurred vision/pain | EMERGENCY → Flush with water → Seek ER care |
4. 3-Step Allergy Prevention
Pre-Test

protect lid with gel that is oil-free
Post-Care
Avoid steam/sauna ×48hrs

A: Look for:
ISO 13485 certification
"Formaldehyde-free" label
EU EC 1223/2009 compliance
