Derma shine pro setting and usage on screen, including needle install will be same on 3rd generation.
Vacuum setting
The vacuum relative to pushing power. In usual higher vacuum cause deeper damage and bigger needle spot. In general, the hyaluronic acid and liquid injection setting on 2-3. But if more sticky serum need to raise vacuum to create stronger power pushing into skin.

Dosage setting
Dosage setting and full capacity. Such as using 5CC syringe serum. Setting valuum 0.01ml each shot. Then 5ml serum support 500 shots. In general one facial doing about 300 shots.
Injection Model
Auto-sensing, auto dose, dose, count normal, count slow. Mostly use auto – sensing. Do not need to hit padder or control speed. The motor control as most people feedback. Once needle touch skin will produce vacuum to lift skin up. After needle inject dosage will release vacuum and pulling needle out. That calls a shot.
Using shot by shot model should combine with pedal. Needle touch skin cause vacuum, hit pedal the needle will inject to skin.
Syringe type
Have 1ml/2ml/3ml/5ml for option. Combing considering and setting with dosage setting.
Needle setting
The adjustable 32G 9pin needle length 0.2mm to 2.0mm. In general needle length setting 1mm for scalp injection and forehead injection. For facial treatment mostly setting on 1.2mm. Some doctors also setting 0.8mm on scalp treatment. But once needle length less than 1.0mm will easy cause leakage because part of needle tip still on plastic part do not entering skin.
There are also other needle type. Such as settle needle length needle, 34G 9pin needle and needle with silicone. The settle length needle and needle with silicone have better sealing. Which means vacuum offer stronger suction power and cause bigger skin damage and spot. In usual for more sticky serum use.
Filter
Filter use to prevent dirty serum or blood comming into machine body to damage machinery.
