Dermatologists participating in the study conducted an analysis of 1,651 skin care products, including creams, soap, and moisturizers.The results show that 90% of these products contain at least 1 of 100 common allergensExposure dermatitis.
The manifestation of contact dermatitis is the red, itchy, worse rash than the blistering reaction at the place of contact with the cause of allergies, or dermatitis.Once exposed to dermatitis, the skin will become more sensitive to other harmless agents.

Exposure dermatitis can be prevented if users identify substances that can cause skin irritation in the list of ingredients listed on the product.However, this is not easy.
Research published in medical magazineJama Dermatology, The American Medical Association published, made to seek the relationship between rapid increase of dermatitis contact with the lack of regulations on advertising in the beauty cosmetic industry.
"It has not yet issued definitions of 'clean' or 'natural' or 'natural' definitions, causing free sellersAnd health benefits to advertise, "dermatologist Peter Young and colleagues participated in research at Stanford Medical University explained.
Typically, a skin care product or cosmetics can contain 15-50 ingredients.Research also shows that, depending on the skin care habits, one can apply more than 500 different chemicals to the skin every day.
Thus, the more skin care products, the more likely you will come into contact with the hidden allergens.
The results of the study showed that allergens commonly found in perfumes, which are likely to be extracted from lavender and plants are the leading agents causing contact dermatitis.
On average, the composition of a product mentioned in the study contains 4 to 5 allergens.A total of 73 different allergens have been listed 7,487 times on 1,651 products studied.
This is only the result obtained when calculating the information available on the Internet, but also shows the size and importance of this issue.
"Users and health care experts need to be warned so that they can be aware of substances applied to the skin," the study concluded.
Research by Dr. Young and colleagues is not the first study to check allergens in personal care products.
In 2017, another study in the US also showed that some moisturizers were labeled "without allergens" and products "without fragrance" sometimes still scent and still haveContains skin irritants.
By labeling "natural", brands make users think that the product they are using is safe.However, consumers have no information on the safety of "natural" products.Sometimes they are fraudulent about the natural origin of the ingredients and compounds similar to "natural substances" chemically.
Along with that, the affirmations "non -allergic" and "certified by the doctor" are used by many brands, in order to create a medical reputation for the product without having to meet a French criterion.reason.
"Consumers and experts need to require evidence from cosmetic companies according to the trend of natural products," the two dermatologists who did not participate in the research were Courtney Blair Rubin and Bruce Brod from the University of Pennsylvaniasaid.
