Experiencing green discoloration on your nails after wearing press-ons is a common issue, often called “green nail syndrome.” This treatable condition has a clear scientific explanation. This article explores what causes green nails, why press-ons contribute, and provides guidance on treatment and prevention.
Understanding Green Nail Discoloration
Green nail discoloration is typically caused by the bacterium Pseudomonas aeruginosa, not a fungal infection. This bacterium produces pigments like pyocyanin and pyoverdin, responsible for the characteristic green, blue-green, or greenish-black hues seen on the nail plate.
Pseudomonas aeruginosa thrives in moist environments and does not typically survive on dry, healthy skin. When it infects the nail, the discoloration is usually superficial, affecting the nail plate rather than deeply penetrating the nail bed.
Common Causes of Green Nails Under Press-Ons
Green nail discoloration, particularly after wearing press-on nails, often stems from conditions that create a hospitable environment for Pseudomonas aeruginosa. A primary factor is trapped moisture between the natural nail and the artificial press-on. This can occur if nails are not thoroughly dried before application, or if water seeps through gaps or areas of poor adhesion during daily activities.
Poor adhesion or “lifting” creates small pockets where moisture accumulates. These damp, enclosed spaces, with limited air circulation, become ideal breeding grounds for Pseudomonas bacteria. Insufficient nail preparation and hygiene also contribute, as existing bacteria or moisture can become sealed in. Prolonged wear, especially with lifting, increases the risk of bacterial growth.
Addressing Green Nail Discoloration
Once green discoloration appears, carefully remove the press-on nail to expose the affected area. Gently clean the natural nail with warm water and mild soap. Keep the nail dry and exposed to air as much as possible, as Pseudomonas bacteria thrive in moist conditions.
Over-the-counter antiseptic solutions can treat the infection. Diluted white vinegar (one part vinegar to four to ten parts water) can be used to soak the affected nail for about 10 minutes, twice daily. Rubbing alcohol is another option for disinfecting the nail. These solutions create an acidic environment unfavorable for bacterial growth.
Avoid covering the nail with new press-ons or polish until the discoloration has completely grown out or cleared, which can take several weeks or months. If the discoloration spreads, the nail becomes painful, inflamed, or if pus develops, seeking professional medical attention is advisable.
Preventing Future Occurrences
Preventing green nail discoloration with press-ons requires meticulous preparation. Thoroughly clean and dry natural nails before application. Using a dehydrator or rubbing alcohol removes any remaining moisture and oils, promoting better adhesion.
Ensuring a proper fit and strong adhesion of the press-on nails prevents moisture from seeping underneath. Apply sufficient nail glue to cover the entire natural nail surface, avoiding gaps where water could become trapped.
After application, minimize prolonged exposure to water, such as extensive dishwashing or bathing, or wear protective gloves to keep nails dry. Regularly inspect your press-ons for any signs of lifting, and promptly remove and reapply them if any separation is noticed. Additionally, allowing your natural nails to breathe between press-on applications can help maintain their health and reduce the risk of bacterial growth.
