Rise in Childhood Contact Allergies Over Two Decades

Recent research from the University of Oulu highlights a notable increase in contact allergies among children in Finland over the past 20 years. The study reveals that allergic reactions caused by chemicals in cosmetics and adhesives have surged significantly, raising concern among healthcare professionals. Contact allergy typically manifests as an itchy, visible rash that can develop anywhere on the skin subjected to allergenic exposure. This condition can sometimes become chronic, potentially impacting a child's future occupational choices.

The research, published in the journal Acta Dermato-Venereologica, underscores the alarming trend of early and increased cosmetic use among children and adolescents. Younger children are now exposed to preservatives and chemicals in skincare products like face masks and lip gloss, while teenagers often use makeup products more extensively than before. The rise in adhesive-related allergies is partly linked to the use of glucose sensors in diabetes management and other products such as eyelash extensions and artificial nails, which involve adhesive application.

Associate Professor Suvi-Päivikki Sinikumpu emphasizes that many parents are unaware of the risks associated with early cosmetic use, which increases the likelihood of developing persistent contact allergies. Such allergies can cause long-term skin issues, including facial rashes, and may influence future career prospects.

This study is particularly significant as no comprehensive nationwide registry had previously documented the prevalence of contact allergies across the entire paediatric population in Finland. The data was obtained from the Finnish Care Register for Health Care, covering children diagnosed between 2001 and 2021.

Overall, the findings highlight the need for increased awareness around early cosmetic and adhesive exposure in children, along with preventive measures to curb the rising trend of contact allergies. Monitoring and education are crucial in reducing these allergic reactions and safeguarding children's skin health.
