Abstract
The prolonged use of the over-the-counter whitening agent, e.g. hydroquinone, could lead to blue-black discoloration of the skin, also known as ochronosis. Other causes include use of phenol, quinine injection, resorcinol application and oral antimalarial. The pathophysiology of this cutaneous condition is unknown and treatment for exogenous ochronosis can be challenging. Combination of microneedle pulsed radiofrequency on top of Q-switched Nd:YAG laser followed by Copper-Bromide laser therapy seems to be an effective modality to treat patients with External Ochronosis (EO). We reported 2 cases of EO resulting from prolonged use of hydroquinone showing satisfying results with the above treatment. We propose that using the above combination as an effective and safe treatment for future exogenous ochronosis cases to come.
