Non-surgical tissue expansion techniques can expand one's surviving penile skin, making it a longer tube so it can function like a [[foreskin]]. <ref>{{REFjournal |last=Collier |first=Roger |author-link= |coauthors= |title=Whole again: the practice of foreskin restoration |trans-title= |language= |journal=CMAJ |date=2011 |volume=183 |issue=18 |pages=2092-3 |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3255154/ |quote= |pubmedID=3255154 |pubmedCID=22083672 |DOI=10.1503/cmaj.109-4009 |accessdate=}}</ref> Men who have been circumcised stretch and apply tension to their shaft and foreskin remnants to expand and elongate tissue in efforts to produce a functional foreskin. This form of tissue expansion can take years, as the amount of skin growth required is typically around 15 square inches.<ref>{{REFweb |url=http://www.noharmm.org/snip.htm |title=Not a "Snip," But 15 Square Inches |trans-title= |language= |last=Hammond |first=T |publisher= |website=NOHARMM |date=2012-02-28 |accessdate=2019-10-10 |format= |quote=}}</ref> This process does not regenerate or restore the function of the [[frenulum]] or the [[ridged band]]. It does, however, typically involve growing more preputial mucosa which serves to moisten and protect the [[glans penis|glans]]. Men who have restored their foreskin typically notice increased sensitivity and dekeratinization of the glans.<ref>{{REFweb |url=http://www.cirp.org/pages/restore.html |title=Foreskin restoration for circumcised men |trans-title= |language= |last= |first= |publisher= |website=Circumcision Information and Resource Pages |date=2013-08-17 |accessdate=2019-10-10 |format= |quote=}}</ref>
