The widespread use of digital devices has led to prolonged exposure to blue light, which is increasingly recognized as a contributing factor in skin damage. Blue light penetrates the skin and induces oxidative stress, leading to premature aging, hyperpigmentation, inflammation, and skin barrier impairment. Conventional topical formulations provide limited protection against blue light–induced damage owing to the poor stability and insufficient skin penetration of active compounds. This study aimed to develop a smart nanoparticle-based topical formulation to enhance protection against blue light–induced skin damage. Nanoparticles are prepared using a suitable technique and loaded with antioxidants and photoprotective agents. The prepared nanoparticles were characterized in terms of particle size, polydispersity index, zeta potential, morphology, and encapsulation efficiency. The optimized nanoparticles were incorporated into a topical dosage form, such as a gel or cream, and evaluated for physicochemical properties, stability, spreadability, and in vitro release behavior. The expected results include improved stability of the active ingredients, enhanced skin penetration, and superior protection against blue light–induced oxidative stress compared to conventional formulations. The nanoparticle-based system is anticipated to exhibit significant antioxidant activity and effective blue-light attenuation, thereby reducing cellular damage. In conclusion, the proposed smart nanoparticle-based topical formulation represents a novel, effective, and safe approach for protecting the skin from blue light–induced damage, offering a promising strategy for next-generation dermocosmetic and therapeutic applications.
