While it is true that in ancient perfumes were the product of a natural process of flowers, are today the creation of some chemicals, which may have consequences for some people, such as allergies.

These are a form of skin reaction against allergens, which may be in contact with the body externally, when in contact with skin or through inhalation.

An allergen is a substance that can induce a hypersensitivity reaction or allergy in susceptible people, who have previously been in contact with it. This hypersensitivity reaction involves recognition of the allergen as a substance "foreign" and alien to the body in the first contact.

Cause. As explained by Dr. Elfid Sánchez, head of the Department of Contact Dermatitis Dermatology Institute and Skin Surgery, contact dermatitis, is usually related to cosmetics, as most of these contain fragrances.

"The styles are different. Contact dermatitis is an allergic reaction or sensitivity type 4 delayed. While allergies by inhalation or ingestion are mediated by type 1 or immediate immunity, "says dermatologist.

In turn, contact eczema can be classified as irritative (most common) and allergies. The irritant contact non-allergic inflammatory reactions are triggered in the skin by applying a chemical that is present with eczematous reaction. Allergic contact eczema is a reaction of delayed type hypersensitivity, which is presented as eczema and dermatitis is caused by skin contact or mucous membranes with a substance to which the patient is previously sensitized.

Time of occurrence. According to Sanchez, the clinical lesions appear on the skin within 14 to 24 hours after exposure to the allergen, however, when the type 1, usually the reactions are faster, practically "Immediately the patient is contacted with the causative agent. "

"When we see a patient with a sensitivity or dermatitis at the neck or face, which are the areas most commonly used fragrances, we think you may have a contact dermatitis to perfumes," said the expert, who also said the confidentiality that exists in the environment to the substances used in the manufacture of perfumes, more complicated the process of determining the allergens that cause allergies or irritation in patients.

Elfid Sanchez said that despite the above, there are standard batteries recommended by research groups of international contact dermatitis, which can contain more than 25 allergens, one of the most frequent Eugenol, the same used in the development of toothpastes we use daily brushing. But something to keep in mind is that there are fragrances and aromas. "The aromas are used in the bakery and are derived from spices or vanilla. Sometimes the patient is cross-sensitivity between fragrance and aroma. When we have a patient who is sensitive to any allergen in perfume, trying to discontinue the aromas, "said the doctor.

Treatment. Sanchez explains that the first treatment is prevention, do not wear perfume directly into the body and advised to use only on clothing. "You can also use cosmetics that are free of fragrance, which are less sensitizing to the patient."

Symptoms

There are some characteristics to determine when it is addressing some of these reactions. In the case of contact dermatitis to perfumes, the lesions usually appear in the contact area of the perfume, neck, behind the ears, in areas where it is usually put on perfume. The lesions are characterized by erythema, or you skin turns red and the appearance of small blisters or vesicles in the affected areas. But here the reaction is a type I allergy may appear edema (swelling) of face, hives, or itching associated with itching of the skin.
