MARCH 20258 APACAPACIN MY OPINIONBY JUN SASAI, VICE PRESIDENT, BASIC AND FUNDAMENTAL RESEARCH DEPARTMENT, BEAUTY INNOVATION CENTER, FINETODAY CO., LTD.NEW NANOTECHNOLOGY TREND IN THE HEALTHCARE AND COSMETIC INDUSTRYNANO MATERIALS SCIENCENanotechnology, the science of manipulating matter at the atomic and molecular scale, is revolutionizing various industries. This article explores the latest trends in nanotechnology applications within healthcare and cosmetics.DRUG DELIVERYOne of the most promising applications of nanotechnology is drug delivery. Nanoparticles can be engineered to carry drugs directly to diseased cells, reducing the side effects of systemic drug delivery. For instance, nanoparticles capable of encapsulating anticancer drugs have emerged. These protect the drugs from degradation and deliver them directly to tumor cells. This approach holds the potential to significantly improve treatment outcomes by more effectively targeting cancer cells and reducing damage to healthy cells.Similar techniques are used in the cosmetic industry to enhance the effectiveness of anti-aging products. Tiny capsules at the nanoscale carrying antioxidants or peptides can penetrate deeper into the skin, combating signs of aging more effectively. For instance, retinol, a popular anti-aging ingredient, is encapsulated in these tiny capsules to increase its stability and penetration into the skin. This allows for a more controlled release of the active ingredient, resulting in improved efficacy and reduced skin irritation.SUNSCREEN AND HAIR CAREIn the cosmetic industry, nanotechnology is primarily used to improve product performance. Nanosized inorganic particles like titanium dioxide and zinc oxide are widely used in sunscreens. These nanoparticles are efficient at absorbing and reflecting UV light and suppressing scattering visible light, providing broad-spectrum protection without leaving a white residue on the skin.In hair care, nanotechnology is being explored to improve hair health and appearance. The idea is to use nanoscale materials to deliver nutrients and active ingredients more effectively. For instance, it is thought that tiny lipid vesicles at the nanoscale could potentially be used to encapsulate active ingredients, ensuring they reach the hair follicles. This could result in healthier, more lustrous hair with less breakage and split ends. However, it's important to note that while the potential of nanotechnology in this area is vast, more research is needed to fully realize these benefits and ensure safety.EMERGING NANOMATERIALSEmerging nanomaterials, such as carbon nanodots derived from natural sources, are showing promise as future Jun Sasai
