A Pendant Necklace That Tracks UV Exposure: Ex-Fitbit Employee Launches Skin Protection Wearable
The90: A New Venture Hits the Market
According to НВ — Техно: On June 12 at 4:00 PM, former Fitbit employee Stacey Salvi unveiled her new company, The90, along with its debut product: The90 Gem necklace pendant. This innovative device is engineered to monitor ultraviolet (UV) radiation. Equipped with sensors that detect both UVA and UVB rays, The90 Gem syncs data to a dedicated app, which builds a personalized skin profile and sends reminders to apply sun protection.
The90 Gem carries a retail price of $300, but early adopters can snag it for $200 for a limited period. Salvi, who spent eight years at Fitbit, emphasized that the modular design of this 'smart' jewelry piece allows for UV tracking in a stylish accessory that can be worn all day and matched with various outfits.
Health Tech Innovation Continues
For context, in 2020 the European Commission approved Google's acquisition of fitness tracker maker Fitbit Inc. for $2.1 billion, with the deal closing in 2021. Stacey Salvi's new product from The90 represents a fresh wave of health and beauty technology emerging in the wake of Fitbit's ownership change.
The launch of The90 Gem signals a growing appetite for devices that blend technology with fashion, as well as a rising consumer focus on healthy lifestyles. It also highlights a trend toward personalized products that cater to individual needs, particularly in skincare and UV protection. With heightened awareness around personal health, this device holds strong potential to gain traction in the market.
