IASO is a wearable low-level laser therapy medical device developed for the relief of musculoskeletal pain. It applies therapeutic laser technology with multiple wavelengths directly to targeted areas and features a compact, lightweight design that can be worn on various parts of the body, including the wrist, shoulder, knee, and lower back. Multiple IASO devices can be used simultaneously to manage different treatment areas, while its rechargeable and wireless design enables convenient use in everyday settings. By combining WellsCare's medical laser technology with wearable device engineering, IASO provides an accessible solution for users seeking convenient and continuous pain management beyond conventional clinic-based physical therapy. IASO is approved by the Korean Ministry of Food and Drug Safety (MFDS) as a Class III medical device.

IASO ULTRA is a high-output wearable cold laser medical device developed for the relief of musculoskeletal pain. Featuring multiple wavelengths of therapeutic laser energy, it is designed with an expanded treatment area and enhanced laser output for more intensive management of larger or chronic pain areas such as the lower back, shoulders, and knees. Its compact, lightweight, wireless design allows users to conveniently apply laser therapy in everyday settings, while multiple devices can be used simultaneously when broader treatment coverage is required. Built on WellsCare's medical laser technology, IASO ULTRA provides a more powerful and professional solution for convenient and intensive pain management. IASO ULTRA is approved by the Korean Ministry of Food and Drug Safety (MFDS) as a Class III medical device.

IASO Pro is WellsCare's next-generation wearable combination rehabilitation medical device currently under development. It integrates multiple wavelengths of therapeutic laser technology with multi-frequency ultrasound into a single platform, with the aim of expanding treatment applications to musculoskeletal pain, edema, lymphedema, and other rehabilitation needs. Compact wearable laser applicators can be positioned on multiple areas of the body for simultaneous treatment, while ultrasound therapy can be selectively combined depending on the treatment purpose. Building on WellsCare's expertise in medical laser and wearable technologies, IASO Pro is being developed as an advanced laser-ultrasound combination rehabilitation platform for professional use in clinical and rehabilitation settings.
