Yes, in some cases stretch marks may become more visible over time, particularly if the skin continues to be exposed to factors that put it under strain. Although the marks themselves enter a white phase and become less biologically active, their structure remains weakened. If there are further fluctuations in body weight, pregnancy or intense muscle growth, stretch marks may widen or appear in new areas. Without treatment, they will not „reverse”, as the damage to the dermis is permanent and requires regenerative stimulation.
