Applicable objects: both roller-shaped and carriage-shaped acne pits can be treated by subcutaneous separation.

Subcutaneous separation: the operation of subcutaneous separation is to insert a needle at the edge of the acne pit, and then rotate the needle parallel to the acne pit to separate the epidermis and dermis at the acne pit, thus cutting off the skin fibers adhered up and down and promoting the growth of dermis. It is said that it is cruel to hear the crackle of fiber breakage during surgery.

The doctor said: after subcutaneous separation, dot matrix laser can get better results.

Recovery period: The wound will be bruised and swollen after operation, which usually takes several weeks to recover.

Cost: according to Asako 40- 100 yuan/piece.

Applicable object: deep acne pits with good elasticity of surrounding skin (individual deep pits)

Layered kerf: You may not find a suitable method for all kinds of difficult acne pits on the surface of the moon and all kinds of acne pits that are ineffective in treatment.

For deep car-shaped pockmarks and ice-cone pockmarks, the effect of laser drilling or strong acid cauterization will not be ideal, just like clothes with holes, laser drilling will only make the holes bigger and bigger, and the elevation will become a slope, which is not conducive to repair, so the layered incision effect is better.

Treatment: Incision of epidermis and dermis (fat layer) according to specific conditions, thorough removal of contracture and subcutaneous tissue with inflammatory cells, cosmetic suture, and later laser treatment.

Cost: 400-800 yuan/piece (generally calculated according to the number of acne pits).

Applicable object: the skin is inelastic and widely fibrotic (pockmarked-pockmarked connection in a large area, pockmarked with skin wrinkles in severe cases).

Micro-skin cell implantation: first do subcutaneous release and mechanical grinding, and then take micro-skin and other cell implantation methods for surface transplantation.

Cost: there are not many hospitals that can do it, and the quotation is generally more than 20,000-30,000 yuan.

Subcutaneous separation, layered incision, and microparticle skin cell implantation are not many hospitals in China, and there are not many doctors who can do it. Probably because of the high technical requirements and long operation time, all doctors who can do it (burn plastic repair experts) have gone to do organ reconstruction, and junior doctors can't do this.
