But unprofessional, it is counterproductive.

For example:

1: Needle selection: No matter what effect you want, a 30-year-old woman can only use 192 needles, because 540 wounds are 30 years older than women.

Slow metabolism.

2: Freeze dried powder. If freeze-dried powder is not a good product, it means that you are injured and can't take medicine.

3. Use chemical skin care products to make your skin more sensitive. Redness, itching, swelling and pigmentation.

4. Operation steps: For example, poor disinfection will make the skin worse. Fortunately, many of them are disinfected with alcohol, as everyone knows.

Alcohol is volatile, but not completely volatile. So wash it again with normal saline.

Lack of operating experience also affects the effect (if the human body has platelets, it will block the wound in time).

Still slow, freeze-dried powder can't get in.

So if there is no full-time professional businessman to guide the operation. You know

I wish you happiness.
