Have you ever sprayed a perfume that smelled incredible on a friend, you’ve rushed out to buy it, only to find it now smells really weird on yourself? It’s not your imagination or a bad batch or anything like that. It can actually be explained by science; chemistry, to be specific. The way fragrance reacts with your unique body chemistry means that it will perform differently on different people.
One of the biggest influences is your skin’s PH level. Skin can be more alkaline or acidic, which can subtly manipulate how the fragrance molecules behave. Perfumes aren’t static, so on some people, specific notes can come across as sharper or sweeter depending on the skin.
Body temperature can also play a role. For those of you who run hot, your warmer skin can accelerate the evaporation and therefore the projection of a scent. This means it may smell stronger at first than with someone who runs more cold. It can also shift how quickly the perfume evolves. Cooler skin will tend to hold the scent closer to the skin, which means it will project more subtly and unfold slowly.
Getting even more sciency, your skin’s microbiome can also interact with your perfume, influencing how long a scent lasts and which notes are emphasised. Skin type goes along with this, with oily, moisturised skin holding onto fragrance better than drier skin, though this can be corrected by applying lotion before perfume application.
Diet and lifestyle are also factors that we can control to some extent, which can contribute to how a scent might unfold. What you eat, how hydrated you are and even your hormones can all alter your natural scent and therefore how the perfume will smell, blending with that.
Understanding this phenomenon can actually be a fun way to help you choose fragrances that feel truly yours.
