We use it almost without thinking, right on one of the most sensitive areas of the body – but is there really any reason for concern?
Spraying perfume on the neck is a common part of many people’s routine. Recently, however, the claim has been spread on social networks that this area should be avoided due to its proximity to the thyroid gland.
But is there evidence that perfume applied to the neck can damage the thyroid?
According to the scientific data so far, there is no evidence that perfume components penetrate through the skin directly into the thyroid gland. Also, it has not been shown that the thyroid is exposed to a greater amount of chemicals just because perfume is applied near it.
The skin acts as a protective barrier. After application, a part of the ingredients evaporates, a part remains on the surface, while some substances can penetrate the layers of the skin and, depending on their properties, reach the bloodstream.
However, a substance that reaches the blood is distributed in the body. The fact that perfume is placed near the thyroid does not mean that it goes directly to this gland.
Part of the concern is related to phthalates, a group of chemicals with various uses. Diethyl phthalate (DEP), for example, can be used in some fragrance products as a solvent or fixative.
Studies have found links between exposure to some phthalates and changes in the levels of some thyroid hormones. However, the results are not consistent, and these studies have not specifically analyzed perfume sprayed on the neck, nor have they proven that it causes thyroid disease.
The fact that a substance can affect the hormonal system under certain conditions does not automatically mean that normal use of a perfume causes clinical harm, reports the Telegraph.
The most documented problem from perfumes applied directly to the skin is allergic contact dermatitis.
It can appears with redness, itching, irritation or eczema-like changes. In some people, perfume can irritate the skin even without causing a genuine allergy.
If the reaction recurs or does not go away, a dermatological check and allergy testing may be necessary.
Perfume and the sun – here you need to be more careful
Some aromatic ingredients can cause phototoxic reactions when perfumed skin is exposed to UV rays.
A well-known example is bergamot, some of whose ingredients can make the skin more sensitive. sensitive to UVA. This can lead to a rash or a sunburn-like reaction.
This does not apply to every perfume, because the risk depends on the composition and concentration.
According to current evidence, there is no evidence that normal use of perfume causes cancer, nor that spraying on the neck creates any special pathway to the thyroid.
So the claim that neck perfume is particularly dangerous to the thyroid gland is not supported by the data. so far.
Perfume on the neck can be avoided if the skin is irritated, itchy or red, if you have eczema or dermatitis, or if you will be exposed to the sun and the product contains photosensitizing ingredients.
Even “natural” perfumes are not necessarily milder, because essential oils can also cause allergies.
So for most people there is no scientific reason to avoid the neck for fear of the thyroid. The most real risks are related to irritation, allergies and, in some cases, skin reaction to the sun.
