Shaving effects on percutaneous penetration: clinical implications

Human/animal shaving biology.

To assess the effect of shaving on percutaneous penetration and skin function.

We screened 500+publications in Pub Med, Scopus, Cochrane Library and pertinent journals out of which only 17 were deemed relevant. Terms for searches included shaving and skin, percutaneous penetration and shaving, skin absorption and shaving, absorption of dyes and shaving, skin penetration, effects of shaving and absorption, shave and dyes, axillary shaving and stratum corneum, shaving and breast cancer, shaving and infections, etc.

Shaving appears to have an exaggerated effect on percutaneous absorption; however, some studies do not support this evidence.

Shaving enhances percutaneous penetration of some chemicals; however this effect is species and chemical specific. Further investigations of chemicals of varying physio-chemical properties are mandated before a generalized theory can be promulgated.
