Specific Operation Steps

Eyebrow Removal

• Parameters: 400–800V, start at 400V; frequency 1–3Hz; distance 2–3cm.
• Key points:

1. Before treatment, confirm whether the customer has scar constitution, allergic skin, or has used other removal methods.
2. For black/blue brows, use 1064nm. If reverse coloration occurs after 5–10 minutes, repeat treatment with slightly higher energy.
3. For light red brows, directly use 532nm.
4. For dark red/brown-red brows: first use 1064nm, then use 532nm. Review after one month and perform second treatment if needed.
5. For covered brows or damaged skin, only treat once, then repeat after one month.
6. Recommended treatment: 2–4 times, once per month.

 

Eyeliner Removal

• Parameters: 300–600V, start at 300V; frequency 1Hz; distance 1–2cm.
• Key points:

1. Strictly protect the eyeball; use an eye shield if necessary.
2. Try to avoid anesthesia.
3. Darker areas may be treated again after one month.
4. Recommended treatment: 1–3 times.

 

Lip and Lipline Removal

• Parameters: 300–600V, start at 300V; frequency 1–3Hz; distance 2–3cm.
• Key points:

1. First test a small point at the lip corner. If the test spot immediately turns black, it indicates iron ions in the pigment – stop the procedure.
2. For black, dark red, or dark coffee lips: first use 1064nm, then 532nm. Repeat after one month.
3. For light red or red lips: directly use 532nm.
4. Lipline or lip blush treatment must be done at least six months after the tattooing, otherwise it may fail.
5. Recommended treatment: 1–3 times.

 

Tattoo Removal

• Parameters: Black/blue – 1064nm (500–800V); red/orange – 532nm (400–600V); frequency 1–3Hz; distance 2–3cm.
• Key points:

1. Operation method is the same as eyebrow removal.
2. Only treat once per session, avoid repeating to prevent blistering or swelling.
3. Recommended treatment: 3–6 times, once per month.

 

Age Spots, Moles, and Freckles

• Parameters: 500–800V, start at 500V; frequency 1Hz; distance 2–3cm.
• Key points:

1. For age spots, first use 1064nm; if no reaction, switch to 532nm.
2. For moles, generally use 1064nm; if no reaction, switch to 532nm. Must reach bleeding point.
3. For freckles (epidermal lesions), usually use 532nm. Be aware of possible bleeding or temporary darkening.
4. Recommended treatment: 3–6 times, once per month.

 

Carbon Peeling (White Doll / Black Doll)

• Parameters: 300–600V; frequency 4–5Hz; distance 2–3cm; large spot size, low energy.
• Key points:
•     Black Doll: Suitable for oily skin. After cleansing, apply a thin layer of carbon powder, leave for 5–10 minutes, then treat full face 1–2 times.
•     White Doll: Suitable for normal/dry skin. After cleansing, operate 3–4 passes over the face, with extra focus on pigmented areas.
•     Recommended treatment: 3–6 times, once per month.

 

Post-Treatment Care

1. Avoid water contact and eyebrow makeup for 3–7 days.
2. Do not eat spicy food; pay attention to sun protection.
3. Avoid heavy sweating and high-temperature environments.
4. Short-term pigmentation changes may appear, usually fading within 1–2 months.
5. Scabs may form – do not pick them, allow them to fall off naturally.
6. Keep skin hydrated, moisturized, and apply physical sun protection (hat, mask, sunglasses).
