Scientists at Stanford University have found that over 94% of cosmetics labeled “natural” on beauty websites contain at least one known allergen and therefore should be used with caution by people with sensitive skin. Research published JAMA Dermatology.
Sometimes, in people with skin allergies, contact with the allergen causes a rash, rash, and itching, symptoms of contact dermatitis that can last for weeks. Such people tend to turn to “natural” cosmetics. A new study has found that these types of foods are just as dangerous, and sometimes more dangerous.
Researchers have studied more than 1,700 “natural” remedies. They found at least one known contact allergen in more than 94% of the products: limonene, eugenol, hexyl cinnamal. They were often found in scents.
The study’s authors recommend that people with sensitive skin purchase products marked “fragrance-free” or “hypoallergenic” and not pursue “naturalness.”
