Q&A

Can you develop allergy to fragrances?

Yes, fragrances can cause allergy. If a product contains one or more fragrances this will be listed on the product as ‘perfume', ‘fragrance' or ‘aroma'. If you buy certified products labeled with The Blue Label you will avoid fragrances and minimize the risk of developing allergy.

Are natural and organic ingredients better for the skin than synthetic?

Many people wrongly believe that organic or natural products are equivalent or the same as allergy friendly. This is not the case. Organic products will often contain ingredients that can give you an contact allergy. One example is the natural fragrance Limonene which is a fragrance that many people is allergic to.

Are you more likely to develop contact dermatitis if you have or have had atopic dermatitis?

  • DMDM hydantoin
  • Formaldehyd
  • Midiazolidinyl urea
  • Methenamine

Related to work you often find formaldehyde in cleaning detergents, cutting oil, paint and paper. In addition formaldehyde is used in the production of plastic, waterbased paint, glue, varnish and construction material.
