What are the benefits of RLT?

According to a 2018 review of researchTrusted Source, many studies suggest promising results of using RLT, but it’s still controversial. Additional clinical research is needed to confirm its effectiveness.

• promote wound healing and tissue repair

• reduce some cancer treatment side effects, such as oral mucositis, radiation dermatitis, and lymphedema

• improve hair growth in people with androgenic alopecia

What are the risks of RLT?

RLT is typically safe and painless. However, experts disagree on whether it is suitable for cancer treatment.

Most studies, such as one from 2022, suggest that RLT may help manage negative cancer treatment side effects.

There have been reports of burns, lesions, and blistering from using RLT units. Some people developed burns:

• after using the device for 30 minutes

• after falling asleep with the unit in place

• due to broken wires or device corrosion

There’s also a potential risk of eye damage. Although LEDs are safer on the eyes than traditional lasers, proper eye protection should be worn during RLT.
