Frequency of Red Light Therapy


The frequency of red light therapy treatments can also vary depending on the condition being treated and the individual's response to treatment. In general, it's recommended to start with 2-3 sessions per week and gradually increase as needed.

For example, a review of red light therapy for pain relief published in the journal Pain Medicine found that most studies used 2-3 sessions per week for 4-6 weeks. A study published in the Journal of Clinical and Aesthetic Dermatology found that red light therapy for acne was most effective when used 2-3 times per week for 4-8 weeks.

It's important to note that while red light therapy is generally considered safe, it's still important to consult with a healthcare provider before starting treatment. They can help determine the appropriate duration and frequency of treatment based on your individual needs and medical history.


For example, a study published in the journal Obesity Surgery found that red light therapy combined with exercise and a low-calorie diet led to significant reductions in body weight and body fat compared to exercise and diet alone. The participants received red light therapy three times per week for four weeks.

Another study published in the journal Lasers in Surgery and Medicine found that red light therapy combined with a low-calorie diet led to significant reductions in body weight, body mass index (BMI), and waist circumference compared to diet alone. The participants received red light therapy twice per week for four weeks.

While these studies suggest that red light therapy may be a promising tool for weight loss, more research is needed to determine the optimal frequency and duration of treatment. It's also important to note that red light therapy should not be used as a substitute for a healthy diet and exercise regimen, but rather as a complementary therapy.
