The dirty manicures to watch out for
<p>New research has uncovered the type of nail polish that harbours the most bacteria after hands are sanitised.</p>
<p>The study, published in the <em>American Journal of Infection Control</em>, found that gel nails, or Shellac, retain the most bacteria after cleaning.</p>
<p>For the study, researchers compared the nails of healthcare workers with standard polish, gel polish and those whose nails were left unpainted.</p>
<p>They then measured the bacterial contamination over 14 days.</p>
<p>The study, which evaluated more than 700 bacterial cultures, found that all types of nails became contaminated over time regardless of the product applied, but gels were the worst.</p>
<p>Acrylic nails aren’t recommended for healthcare workers as sanitising hands is more difficult, but researchers explained that little is still known about gel products.</p>
<p>Gel nails require curing or hardening under an ultraviolet light and are popular because it is believed they are gentler on natural nails.</p>
<p>Shellac nail polish has risen in popularity over recent years due to celebrity endorsement.</p>
