Use 2 wooden tonguers with 1 cm or 2 cm width and begin from the intergluteal cleft (in) towards the external (out).

Use 2 wooden tonguers with width of 1cm or 2cm and proceed from infra gluteal fold to upper limit of the butt ( upper limit of the underwear-string).

Proceed in the whole gluteal area as described before to obtain squares .

• Even if we used 2 wooden tonguers in their width to divide in squares the gluteal area, all squares will be different ( some will be bigger and others smaller ).
• In such case, the quantity of product to inject should be more than average for larger squares 
• Average injection per square per vector or /and tensor is 0.1ml
• For bigger squares : 0.2 to 0.3 ml per vector and/or tensor
