Dermatologist Promotes Sunscreen and Antiaging Benefits of Nanotechnology

But nanotechnology does not just have benefits in sunscreen, according to Nasir. It also can deliver antiaging ingredients such as retinoids and antioxidants topically. Nasir noted that many of these ingredients such as vitamin C are not stable and are unable to penetrate the skin. He found that nanotechnology could not only make them stable but also could help them penetrate the skin.
Nasir continued that there are a number of dermatology-related uses for nanotechnology. He added that drugs such as botulinum toxin or growth factors may be able to rejuvenate the skin topically when nanosized. Nanosized gold, known as gold nanoshells, was referenced by Nasir as a possible treatment for melanoma. In mice, these nanoshells, have been shown to heat up in cancerous tissue to effectively kill the area. Non-invasive treatments for atopic dermatitis and ichthyosis also could be created with nanotechnology.
Although he finds benefits in nanotechnology, Nasir is still awaiting safety reviews. “We anxiously await the FDA’s review of the safety of nanoparticles which will determine their future role in skin cancer products,” he concluded.
