Do body lotions enter into bloodstream of people? And how do they do it?
Lotions, like any other drug, can effectively enter the blood system. However, the fraction of the applied lotion that actually enters is really small, and it only achieves a significant concentration in the zone near the application. The skin, if healthy, offers a very high resistance to the passage of substances. Moreover, the bloodstream actually dilutes even more the little fraction it achieves to enter, further reducing its effects. If the skin is damaged the penetration is greater, though you'll never be able to get drunk by dropping booze in an injury.
