Green nail discoloration after applying press-on nails is common. While startling, it’s typically not a severe health concern, but it does signal an underlying issue requiring attention.
Understanding the Green Discoloration
The green color on your nails is primarily caused by Pseudomonas aeruginosa bacteria, a condition known as “green nail syndrome” or “chloronychia.” These bacteria are widespread in nature, found in soil, water, and on human skin, but they do not thrive in dry, healthy environments.
The discoloration results from pigments produced by the bacteria. When moisture, warmth, and lack of air circulation are present, such as between a natural nail and a lifting press-on, these bacteria find an ideal environment to multiply and release their distinctive green waste products.
Addressing the Green Discoloration
If you discover green discoloration after removing press-ons, gently remove any remaining artificial nail material. Clean the affected nail thoroughly with warm water and mild soap to eliminate debris and bacteria. Keeping the nail dry and exposed to air is important for healing.
For mild cases, soak affected nails in a solution of one part white vinegar to four to ten parts water for about 10 minutes twice daily to inhibit bacterial growth. After soaking, dry the nails completely. While the green tint may take time to disappear as the nail grows out, this method helps. If the discoloration spreads, or if you experience pain, swelling, broken skin, or nail separation (onycholyisis), consult a healthcare professional, such as a dermatologist. They may recommend topical antibacterial agents or other treatments if the condition is persistent or severe.
Preventing Green Nail Discoloration
Preventing green nail discoloration involves careful preparation and maintenance when using press-on nails. Begin by ensuring your natural nails are thoroughly clean, dry, and free of oils before application. Using an alcohol wipe to dehydrate the nail surface can help create a better bond and prevent moisture from becoming trapped.
Proper application of the press-on nails is equally important, including selecting the correct size that fits flush to your nail bed to avoid gaps. Apply an adequate amount of adhesive to prevent air pockets, as these spaces can trap moisture and foster bacterial growth.
After applying press-ons, it is beneficial to avoid prolonged exposure to water for several hours to allow the adhesive to fully cure. For activities involving extended water contact, such as washing dishes, wearing gloves can provide a protective barrier. Taking breaks between press-on applications also allows your natural nails to remain dry and helps maintain their overall health.
