Nanocrystals: A Multifaceted Regimen for Dermatological Ailments

Skin disorders are the most common apprehension worldwide among different regions of the world. Topical route of administration offers benefits over other routes such as avoidance of first‐pass metabolism, low dose, longer residence time, and absence of off‐target delivery. Skin serves as a mechanical barrier for therapeutic delivery with selectively permeable essential molecules. Considering the structural complexity of skin, delivery of therapeutics at targeted site requires sophisticated method such as nanotechnology‐assisted therapeutic delivery. The roadmap for combinatorial approach of nanotechnology and skin therapeutics has proven significant in clinical and marketed products. Currently, various pharmaceutical aids such as nanocrystal (NCs), nanoparticles, nanoemulsion, nano‐micelles, nano lipidic carriers, and hybrid nanocarriers are currently in market. Among all the other nanocarriers, nanocrystal offers precedence over other nanocarriers due to its facile method of preparation, reproducibility, low excipient concentration, and high therapeutic loading capacity. The recent literature data suggest the breakthrough evolution of NCs in topical therapeutic delivery. The outcome of these interventions envisages the applicability of NCs for delivering molecules with compromised physicochemical characteristics such as solubility, stability, toxicity, and bioavailability concerns.
