Thermasol announces a single tub for cold and warm immersion
New equipment announcement · manufacturer specifications · sales date is planned
Thermasol says the single-user Obsidian Recovery Tub combines a chiller and heater with touchscreen and Wi-Fi controls. It lists a 37°F to 104°F temperature range for the equipment. The manufacturer announced the model on November 5, scheduled a showcase at BDNY and lists December 1 as the planned sales start. We verified the published dates and specifications. Retail inventory and real-world temperature performance remain unverified.
Why it matters for buyers: Start with the installation. Ask the installer to check the filled load, dedicated circuit, access for delivery and drainage. The manual includes filter changes and water care, so budget for replacement filters and ask who can service the heater and chiller locally.

Dermalux adds a wearable LED device for the neck and upper chest
New manufacturer announcement · cosmetic claims unverified · FDA record applies to a separate model
Dermalux announced the Neck & Décolletage LED Device after trade coverage appeared earlier in the week. The brand lists 633 nm, 830 nm and 1072 nm emitters and markets the wearable for cosmetic skincare. We verified the published specifications and the FDA record for the separate Flex MD model. U.S. clearance for this wearable and the brand’s cosmetic outcome claims remain unverified in our review.
Why it matters for buyers: Compare the area the device actually covers, how it fits at the shoulders, the exact model’s safety labeling, and the return policy for opened devices. If a seller cites FDA clearance, ask for a record that names the model you would receive.
