METHOD FOR DERMAL PIGMENTATION OF HUMAN EYEBROW SKIN Russian patent published in 2023 - IPC A61M37/00 

Abstract RU 2790767 C1

FIELD: cosmetology.

SUBSTANCE: first, the sketch is fixed within the contour previously drawn with a pencil by filling the surface of the skin of the eyebrow with arrays of strokes overlapping and end-to-end with each other in the direction from the tip of the eyebrow to the head of the eyebrow, using an electromechanical tool held at an angle of 90 degrees to the skin surface, with sweeping pendulum movements away from the master, with a gradual change in the depth of penetration of the needles into the upper layer of the dermis, with a smooth exit from the skin at the end of the arcuate stroke along the arc trajectory. Each next array of strokes is shifted in the direction of the eyebrow head by 2 mm, thereby filling the gaps in the previous array of strokes, according to the artistic concept. At the same time, the filling of the tip of the eyebrow to the apex point is carried out with arrays of strokes 5 mm long, penetration depth into the skin is 1.52 mm with increments of 1 mm, forming a pattern on the skin in the form of a drop-down fan. When filling in the body of the eyebrow, the length of the strokes increases to 10.0 mm, the depth of penetration into the skin to 1.5 mm in increments of 1 mm. When filling in the head of the eyebrow, the length of the strokes increases to 15.0 mm with a simultaneous decrease in depth to 1.0 mm. When performing the second pass, the strokes are applied with movements “towards the master”, the layers of arrays of strokes form a pattern in the form of a lattice on the pigmented area. When performing the third final pass, pigmentation is carried out in the opposite direction, namely in the direction from the head of the eyebrow to the tip of the eyebrow.

EFFECT: ensuring a visual effect of natural eyebrows, giving the face expressiveness, attractiveness, a finished and well-groomed appearance; evenly painting over pigmented areas; reduction of the time of the procedure, reduction of the risk of injury to the skin and increasing the long-term effect of permanent makeup; increasing the motor activity of the master when changing the position of the body.
