Allergy-Friendly Detergents Safe for Atopic Dermatitis Patients
Key Takeaways
Sensitive skin detergents tested did not disrupt skin microbiome viability or diversity in atopic dermatitis patients.
Participants reported high tolerability with no worsening of atopic dermatitis symptoms.
Findings support the use of allergy-friendly detergents for individuals with sensitive skin conditions.
A recent clinical study found that two laundry detergents marketed for sensitive skin do not negatively impact the skin microbiome or worsen symptoms of atopic dermatitis (AD).
The study was conducted in 41 participants diagnosed with AD. For the present study, the researchers evaluated the microbiome compatibility and tolerability of Persil Sensitive Gel and Persil Megapearls Sensitive detergents. Participants wore socks washed with these detergents for seven days, after which their skin microbiomes were analyzed using swab samples.
Results indicated no significant changes in bacterial viability or biodiversity for either detergent. Both of the detergents were highly rated for tolerability, with participants reporting minimal itch and no adverse effects on AD-related skin conditions. Bacterial diversity remained stable, and the prevalence of beneficial bacteria such as Staphylococcus epidermidis was unaffected. No detection of the pathogenic Staphylococcus aureus was reported.
The authors noted limitations in applying results to other body parts or skin conditions due to the study's focus on foot microbiota and emphasized the need for further investigations to confirm these findings.
"This study provides valuable information about laundry detergent effects on microbiome fluctuations and influence on skin-allergic symptoms of AD patients," the authors concluded in the study. "The results of this study suggest that AD patients can use the tested laundry detergents without any concerns of negative impacts on their skin condition. Given the significance of maintaining a healthy skin microbiome, further research in this area is crucial to develop recommendations for maintaining skin health."
