Study Reveals Chemical Basis for Teenagers' Distinct Body Odor

Researchers identify steroids and carboxylic acids unique to teenagers, shedding light on puberty's role in body scent changes.

Scientists have identified the chemical compounds responsible for the distinct body odor in teenagers, which includes notes of cheese, goat, urine, and musk.
The study found that two specific steroids and elevated levels of six carboxylic acids are exclusive to teenagers, contributing to their unique scent.
Infants, in contrast, were found to have higher levels of a ketone that smells like violets, along with a pleasant, soap-like odor.
The onset of puberty activates sweat and sebum glands, leading to the production of these odor-causing compounds through microbial action.
Understanding these chemical changes could aid in the development of more effective deodorants and personal care products for teenagers.
