Nanotechnology Increases Effectiveness of Skin Products

Nanotechnology may have a future in cosmetic products, as researchers continue to study the effects of nano-sized particles in topical skincare solutions including sunscreens and anti-aging serums.

Several major cosmetic manufacturers are waiting for the U.S. Food and Drug Administration to approve the safety of the technology, and are still researching the side effects and outcomes of certain applications.

Products that incorporate nanotechnology are being manufactured at a steady rate, and many clothing manufacturers are already making use of the nanomaterials to increase wrinkle resistance and water repellance in certain types of clothing. The cosmetic industry has begun developing products that can enhance the effects of sunscreen, lipstick, eye shadow, shampoo, conditioner, moisturizer and even certain types of perfumes.

Dermatologist Adnan Nasir, MD, PhD, FAAD, clinical assistant professor in the department of dermatology at the University of North Carolina in Chapel Hill, presented an overview of nanotechnology and how nanoparticles may eventually be used in cosmetic products at the 68th Annual Meeting of the American Academy of Dermatology in Miami this past month. Dr. Nasir states, “Research in the area of nanotechnology has increased significantly over the years, and I think there will be considerable growth in this area in the near future…the challenge is that a standard has not been set yet to evaluate the safety and efficacy of topical products that contain nanosized particles.”

Dr. Nasir reports that nanotechnology does offer a number of benefits for use in anti-aging products, and when properly engineered, may be able to deliver topical products such as retinoids and growth factors deep into the skin’s layer for enhanced skin rejuvenation benefits. For the consumer, these products may be a little more expensive than traditional products, but may be more effective in the long-run because they can produce better results and improve the health and resilience of the skin overall.
