Creams and lotions may contain harmful substances

Creams and lotions may contain harmful substances

Urea, petroleum, parabens and dyes are common ingredients in most cosmetic formulas around the world. They help fight against dryness, premature aging and other skin problems, but can be potentially hazardous to health. In contact with the skin, they can cause irritations and skin allergies and even increase the risks of serious diseases, such as cancer.

The consumer hardly identifies the ingredients that can be harmful because they do not know the nomenclatures used in the labels. Formaldehyde derivatives, which contain odor, can be camouflaged by pleasant aromas.

The most common adverse reactions are allergies, which can cause edema, pruritus (itching), or local hypersensitivity. Minibars, known as vesicles, scaling, eczemas and crusts also indicate that the cosmetic is not doing well.

The factor that triggers the reaction depends on each organism, but is usually linked to the amount used and frequency of use. Not always the allergy manifests itself immediately. Over the long term, and in large amounts, preservatives can cause liver and kidney problems. Continuous use of benzophenones, a substance found in many sunscreens, can cause hormonal changes.

Simplifying the routine is one of the options

"The frequent use and the adequacy of the cream used can trigger the appearance of skin reactions"

Preferring cosmetics with less dyes, essentials or preservatives may be an option. You have to be careful, because it is very common to think that we are using a natural product, when in fact it presents in its composition several chemical ingredients embedded. It all depends on knowing which substance we are sensitive to. For this, the ideal is to talk to the dermatologist.

If the idea is to reduce the risk of allergies, it is not recommend organic products. The fact that they do not use chemicals in their composition does not make them free to cause some kind of allergy. Hypoallergenic are most indicated.

As almost no cosmetic is tested on pregnant women, they are prohibited from using a number of substances. The main ones are derivatives of vitamin A, such as retinoic acid, acitretin and isotreinoin, hydroquinone and immunosuppressants, such as cyclosporin and azatiorpin. Antifungals, such as ketoconazole, should also be avoided because they can cause problems in the fetus, such as malformation, miscarriages and premature delivery.

Pregnant women should be aware

"Most active substances should not be used in pregnant women, especially in the first trimester of pregnancy. "

In pregnancy, urea is not indicated because it easily crosses the placental barrier and also increases the absorption of other active substances by up to 3%, but is released by Anvisa. Most of the assets should not be used in pregnant women, especially in the first trimester. In the event of suspected pregnancy, the use of cosmetics should be discontinued and a dermatologist should be consulted.

To avoid allergies and other health hazards at any stage of life, it is advisable to consult a physician before using any product.
