On the finish of the examine’s 16 weeks, each teams skilled improved pores and skin elasticity and higher dermal construction, however the group who solely did weight coaching additionally had improved dermal thickness. That’s essential as a result of the dermis—an elastic help construction mendacity simply beneath the pores and skin’s outer layer (dermis) that incorporates nerves, blood vessels, and glands—thins progressively over time, contributing to pores and skin sagginess and different indicators of damage and tear.
