Onycholysis is the separation of the nail from the nail bed. Photoonycholysis is onycholysis induced by sun and a photosensitizer, e.g. tetracycline, doxycycline. It has been reported in association with UV radiation exposure during nail gel manicures.


The sun exposure should cease. If needed, the medication may be stopped. The nail should grow out and return to normal.
