The British fragrance industry was treated to scientific and creative presentations on the theme of smell and memory at the 2023 IFRA UK Fragrance Forum, which took place yesterday in London.
Hosted by the UK branch of the International Fragrance Association, talks discussed in-depth how we scent, experience and remember different aromas.

Or, at least, what begins as a clear code produced by every odour is eventually muddled in the brain.
