The theoretical basis of losing weight with perfume is that losing weight with perfume is not really about losing weight, but using the olfactory system to reflect different scents to convey the magical effect that this person smells thinner, which is exactly the same as the internationally popular aromatherapy. Aromatherapy is the use of essential oils to relieve mental stress and improve physical health. Aromatherapy not only depends on the medical properties of essential oil, but also emphasizes the all-round reflection of essential oil by human brain and body, including smell. Modern industrial perfume is not made of essential oil, so it does not have the chemical basis of essential oil aromatherapy, but the influence of taste on human senses has always been recognized: human olfactory system will directly transmit some information to the nerve center of the brain, and then reflect some images from the brain. This has become the theoretical basis for some perfumes to make people "slim". What kind of perfume makes people smell slimmer? Grass green perfume is the first perfume that makes people smell slimmer. The representative perfume of grass green perfume is tea fragrance, such as Arden green tea lady perfume, BVL Darjeeling tea and black tea neutral perfume. The taste of bitter tea or citrus in this fragrance can tighten the human body curve, and the image reflected by the scented person tends to be "slim".
