Treatment

Postpartum stretch marks result from the mechanical rupture of collagen and elastin fibers in the dermis, caused by the rapid stretching of the skin during pregnancy. This leads to linear atrophic lesions characterized by disorganized extracellular matrix architecture, thinning of the epidermis, reduced fibroblast activity, and, in mature lesions, significant loss of dermal volume and dyschromia.

The 1,340 Nd:YAP ProDeep® fractional laser emits controlled thermal microzones (MTZs) in the deep dermis, inducing a photothermal lesion cascade that stimulates the synthesis of new collagen, correcting the structural deficit underlying the stretch marks. The 2,940 nm DualMode® fractional laser complements the protocol by acting on both the epidermis and dermis, improving skin color and remodeling the texture of the skin's surface.

The combination of the two technologies promoted the progressive reorganization of collagen and elastin fibers, with a reduction in erythema, improved texture, and normalization of skin color.

After 8 months with a monthly interval, the clinical objectives were achieved, with a significant reduction in scar relief, regression of erythema, normalization of melanin, and measurable improvement in skin texture and elasticity, as evidenced in the images.
