Dermal patch

A dermal patch is a medicated patch that is applied to the skin where certain types of drugs are absorbed through the skin into the person's bloodstream. In real-life modern-day usage, dermal patches are used for weaning people off of using certain types of addictive drugs such as nicotine which is found in tobacco.

In the EMPATH: The Luckiest Smurf story series, dermal patches are used in Psychelia to administer psychelium to Psyches who are considered a threat to their society when they begin to lose control over their emotions. Papa Smurf also developed dermal patches for administering certain types of potions to his little Smurfs.
