FDA cleared Biolinq Shine for over-the-counter sale, and the company announced it on September 24. The clearance covers adults 22 and older who are not taking insulin. Shine reports glucose ranges and trends, not values for dosing.
Shine already held a De Novo classification, granted in September 2025 for adults with type 2 diabetes not on insulin. That De Novo created the device type. The 510(k) a year later removes the prescription.
The sensor is a coin-sized forearm patch. Its microsensor array sits in the top layers of skin, which Biolinq puts at up to 20 times shallower than filament-based CGMs. A color-coded LED on the patch shows the range with no phone in the loop, and a companion app adds detail.
That labeling puts Shine in the retail biosensor aisle with Dexcom Stelo and Abbott Lingo rather than against prescription CGM. The San Diego company raised $100M in a Series C in April 2025, after $58M in 2024.
