Professional Treatment Rules
1. Always start lower
Begin with the lowest effective depth and increase gradually.
2. Sensitive areas = shallow depth
Under eyes and neck should always stay minimal.
3. Deep areas = controlled zones
Cheeks and nasolabial folds tolerate deeper settings.
4. Never use one depth for the entire face
Customize per zone for best results.
Recommended Strategy (Salon Use)
- Anti-aging treatment: 0.5 – 1.0 mm overall + deeper cheek zones
- Acne scar protocol: 1.0 – 1.5 mm cheeks + 0.5 mm surrounding areas
- Sensitive skin protocol: 0.25 – 0.5 mm full face
- Lifting treatment: jawline + cheeks at 0.75 – 1.25 mm
