Biosensor Research Institute Launches 'Naked Sunshield' Golf Patch

‘Franz Skincare,’ a brand under Biosensor Research Institute Co., Ltd. located at Seoul National University, introduced the transparent UV protection patch ‘Naked Sunshield Patch’ on the 8th.

The Naked Sunshield Patch is a transparent and thin multi-functional outdoor sun patch with UPF 50+, blocking 99.9% of UV-B and 95.8% of UV-A rays, providing up to 99.9% UV protection throughout the day.

Compared to sunscreen, which the FDA recommends reapplying every two hours, the Naked Sunshield Patch neither melts nor falls off, maintaining UV protection all day with just one application.

As a result, even during hot summer outdoor activities like exercise that cause heavy sweating, sweat is immediately released outside the patch, allowing comfortable outdoor activity.

Additionally, the Naked Sunshield Patch has been rated non-irritating in skin irritation tests, making it safe for children aged 3 and older. The application method is similar to the familiar tattoo sticker style, allowing easy attachment and removal for people of all ages and genders.

A representative from Biosensor Research Institute stated, “The Naked Sunshield Patch is a product developed through over 100 formulation tests by our in-house research team, achieving a thickness more than six times thinner than hair and transparency. Unlike existing golf patches, it allows tinted makeup, so users can take selfies with their natural face, making it popular among many women. It also does not come off with water or sweat, making it a great alternative to sunscreens that run when wet, and highly useful for water play and various outdoor activities.”

Meanwhile, the product is available at the Franz Skincare official online store operated directly by Biosensor Research Institute Co., Ltd., and a promotional event is currently underway to celebrate its launch.
