Obesity lines in men can be eliminated by fractional laser, microneedling, and medication. Fractional Laser: Fractional laser involves the delivery of narrow columns of laser light to the skin in order to produce thermal damage to vertical zones and induce the damage healing process, thereby improving pigmentation abnormalities and skin texture. Microneedling: Microneedling involves the insertion of a set of fine needles into the skin to cause damage to the dermal columns, thereby stimulating neocollagenesis, which induces tissue remodeling and neocollagenesis for the elimination of obesity lines. Medication: For patients who are unable or unwilling to undergo fractional laser treatment and microneedling, topical retinoic acid treatment can be tried, but current research is not clear whether topical retinoic acid is effective for obesity lines. If obesity lines appear, it is recommended to go to the hospital in time for early formal treatment.
