Antiseptics are typically small simple molecules such as ethanol, or soap, or phenol, that kill all types of cells (including your own) by non-specific mechanisms, such as disrupting cell membranes. They are never taken internally, as they are poisons.
Antibiotics, whether applied systemically or topically, are more-complex molecules that bind to specific molecular targets in bacteria or fungi and disrupt their functioning. Because they bind to microbial proteins, and not human ones, they have very low toxicity.

Antiseptics are antimicrobial substances that are applied to living tissue/skin to kill germs and reduce the possibility of infection or sepsis.
They are different from antibiotics that destroy microorganism within the body.
Ethyl alcohol or ethanol is the most commonly used antiseptic.
Boric acid and hydrogen peroxide are also used as antiseptic.
There are many types of antibiotics including penicillin, streptomycin, chloramphenicol, sulphonamides and many others, which are taken as tablets or administered by injections to fight infections.
