Perfume has been used for thousands of years and is still very popular today. The perfume industry makes billions of dollars each year by developing and selling new fragrances. However, because no two people are alike as far as their body chemistry goes, each fragrance can smell different from one person to the next. Body chemistry includes things such as the amount of perspiration on the skin, hormone levels, oils or medications excreted through the skin.
If under stress, be aware that it can affect the body's chemistry by increasing the heart rate, thereby generating more heat or causing sweating that can alter the scent. Apply perfume to the pulse points, the area where the blood vessels are close to the surface and create the most heat -- the wrists, neck and behind the ears. Smell the fragrance throughout the day to see if the scent lingers or fades away quickly.
Eating certain foods can alter body chemistry and make fragrances smell different, most notably onions or garlic. The smell of garlic will drift out through the pores in the skin and can mix with perfume in an unpleasant way.
The aging process can change the body's chemistry due to hormonal fluctuations. A perfume that used to smell good can change with the increase or decrease in hormone levels.
Skin type can determine the way perfume smells. Certain skin types absorb the oils in perfume and cause the scent to vanish quickly. A person with this skin type will need to test many different fragrances to find one that will last.
