Artificial nails may look glamorous, but dermatologists warn they can sometimes trigger nail psoriasis, especially in people with sensitive skin. The condition is linked to the Koebner phenomenon, where even small injuries to the skin or nails can spark psoriatic lesions.

According to Dr. Sonali Kohli, Senior Consultant Dermatology at Sir HN Reliance Foundation Hospital, patients with mild psoriatic tendencies often develop changes in their nails just 2–4 weeks after aggressive nail treatments. Common warning signs include nail pitting, oil-drop discoloration, thickening under the nail, or brittle texture.

It’s not just physical trauma like over-filing or harsh removal techniques that cause damage - chemicals in nail glue, acetone, UV curing, and strong removers can also create inflammation. Together, these weaken the nail barrier, making it easier for irritants to penetrate.

Experts suggest prevention is key. Choose trained nail technicians, opt for gentler application methods, use non-acetone removers, keep nails hydrated, and take breaks between artificial nail applications. If psoriasis develops, early treatment with creams, supplements, stress management, and medical care can stop it from spreading to the skin.

Bottom line: artificial nails are not unsafe if done responsibly, but those with autoimmune sensitivity must be extra cautious.
