Is Low Fluence Nd:YAG Effective and Safe for Treating Senile Lentigo?
Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser treatments are popular and effective for treating many pigmentary conditions, but may lead to post-laser hyperpigmentation for some patients. A low fluence Nd: YAG treatment, also known as laser toning, may be a better option for treating benign lesions such as senile lentigo.
Senile lentigo, while not harmful to health, consist of well-defined, annular or ovoid, uniform tan to brown, small macule or patches, found mostly on sun-exposed skin, such as the face, dorsal hands, and extensor forearms. A recent study sought to examine the efficacy of using laser toning to treat these pigmentary lesions. This small, retrospective case study included 12 patients who were treated at least four times with low fluence 1,064 nm QS Nd:YAG laser for skin brightening. Patients were older than 40 years of age and had moderate to severe grade of multiple senile lentigines on the face.
The results showed that most patients experienced marked improvement or more satisfactory results without permanent injuries, such as scarring or pigmentary changes. These changes were achieved in as few as three sessions. However, limitations such as the small sample size and retrospective design preclude any cause-and-effect conclusions.
The authors state that laser toning could be a new approach to treating senile lentigo, especially due to the safe profile of the laser. If patients need to avoid recovery downtime or who are at risk for post-inflammatory hyperpigmentation, this may offer an acceptable alternative to conventional laser systems.
