Red Light Rejuvenation Therapy

What Are the Benefits of Red Light Therapy? Acne Often acne is accompanied by a fair amount of inflammation. Red light therapy helps to calm and decrease redness, and minimize oil production and bacteria on the skin. Zubritysky says it is ideal for the mild to moderate treatment of acne.   According to a 2018 study, "acne and sensitive skin are often associated due to the involvement of an impaired skin barrier in both conditions, which can be further aggravated by certain topical acne treatments...therefore, a nontopical, chemical-free treatment that is well tolerated by patients with self-perceived sensitive skin for use in the treatment of acne is highly desirable."3  Anti-Aging One of the most popular uses of red light therapy is for its anti-aging benefits, and for good reason: There are an abundance of studies to support its positive anti-aging effects. A 2019 study from The Journal of The American Academy Of Dermatology found that red light therapy increases production of collagen, elastin, and hyaluronic acid in the skin. This, in turn, can help with skin laxity, fine lines, pore size, texture, and wrinkles, making low-level red and infrared light treatments ideal "opportunities for daily, at-home treatments for patients with photo-aging and photo-damaged skin."1  Wound Healing Have a scar you would like to fade? Red light therapy can help minimize scar tissue as it helps boost circulation and brings more oxygen to the area.4  Cold Sores If you deal with reoccurring cold sores (oral herpes simplex virus), red light therapy can help accelerate healing time and decrease pain associated with these lesions.5  Hair Loss For alopecia—specifically androgenetic alopecia, also known as male and female pattern hair loss—some studies support red light therapy as an effective treatment.6 It may not work for everyone, and is best used in the earlier stages of hair loss and for less severe cases. Once the hair follicle has been scarred, it is unlikely to be effective.  What to Expect During a Red Light Therapy Treatment Unlike some beauty treatments, you don’t feel a whole lot with red light therapy. Once the light warms up, you will feel some heat on your skin, but most find it to be very tranquil and relaxing.  At-Home vs. Professional Red light therapy can be performed in a professional setting as part of a dermatological procedure, as part of a facial treatment by an esthetician, or with an at-home device. You may even see red light therapy treatment booths pop up at your fancy gym. Both professional and home tools come in a large variety of devices, but are most often found in a single or tri-panel handheld wand, mask, or even a full-body bed or stand-up panel. Keep in mind that the at-home version may be less potent than the professional version, but they are still very beneficial.  If you plan on using red light therapy at home, make sure you do your homework while looking for devices, especially with so many on the market. The sweet spot for both therapeutic and cosmetic benefits is between the mid-600 to 900 nanometer.7  The jury is still out on the exact ideal frequency for red light therapy, but it's most commonly recommended that the lights are pointed at the skin several inches away for a number of minutes, depending on the manufacturer's instructions. The treatments are painless and require no downtime. The benefits are cumulative, so it's essential to be consistent to reap all the benefits.   Does It Really Work? Yes; it can be useful and effective when used appropriately, realistically, and in some cases under the supervision of a board-certified dermatologist, Zubritsky says. For example, it can be an excellent complementary treatment for mild acne cases in combination with other acne treatments like topical products or medications.8 However, it may not totally clear particular types of acne like cystic acne.   Many studies support red light therapy as an effective treatment modality in treating pre-cancerous lesions like actinic keratoses.9 It's typically used with a topical photosensitizer to be effective.
