At the Joanna Vargas Salons in New York City and Los Angeles, several different forms of light therapy treatments are offered. But what is red light therapy, you might be asking. Does red light therapy work? Is red light therapy safe? Depending on your skin type and concerns, the answer is Y E S.
What is Red Light?
Red light therapy (RLT) is a controversial therapeutic technique that has been used since the early 90s. While experimenting on getting plants to grow in space, scientists discovered that intense light from red-light emitting diodes (LEDs) helped promote growth and photosynthesis of plant cells.
Red light was then studied and researched in medicine. If red light helped grow plants cells, what was the benefit for human cells? Scientists were able to discover that red light therapy could increase energy in human cells, resulting in many benefits. But how does it work?
Unlike ultraviolet rays from the sun which damages the DNA of skin cells, red light emitted into the skin is perfectly safe. When your cells hit the red light, it begins a regenerative process. This process helps lead to many benefits that are listed in the section below.
Red light therapy works by rejuvenating the skin and not damaging it, by delivering safe, concentrated wavelengths of natural light into your skin (around five millimeters, to be exact). It is then absorbed by your cells, where they begin to recharge.
In the skin care realm, light therapy is administered via a until of small panels, directed at the skin from just a few inches away. Light like this has the ability to penetrate skin on a far deeper level than any tools or products can and with absolutely no discomfort or invasion.
LED lights come in different spectrums, including infrared and blue (which helps kill bacteria and subsequently vanquish acne). Besides being completely non-invasive, there are other benefits to incorporating light therapy in your life.
There are different kinds of light therapy, with LED infrared light therapy being the most popular for a youthful glow. Our LED beds, patented by Joanna Vargas herself, are made with healthy lights that do not have the same harsh effects on the skin as UVA or UVB rays. This "anti-tanning" bed offers various benefits to cure sunspots and burns on the body in each session. The infrared red light activates the body’s natural healing powers, stimulating cell turnover and jump-starting the reparative process to reverse signs of aging and promote well-being.
What are The Benefits?
Since everyone reacts differently to light therapy, depending on your age and skin condition, the more treatments, the better the results. Not only will this help with sunspots and burns, but red light also helps to temporarily minimize the appearance of cellulite and stretch marks, fine lines, acne scars and scars from injuries, and pores.
Red light therapy can even help with muscle repair from sore muscles from the gym or overall muscle repair from working out activities or an accident. It could also be helpful for pain relief if you suffer from inflammation, body pains and aches such as back or knee pains.

Can You Combine XERF with Botox, Filler, or Lasers?
Yes, XERF may be incorporated into a treatment plan with Botox or other neuromodulators, dermal fillers, biostimulatory injectables, lasers and selected ultrasound procedures. XERF uses noninvasive radiofrequency energy to heat tissue and support skin tightening, while neuromodulators address expression lines, fillers restore volume, and lasers may target pigmentation or texture. However, these treatments are not automatically safe to perform together or on the same day. Radiofrequency heating may affect certain existing fillers, and sequencing depends on the product, treatment area, settings and medical history. At Joanna Vargas in New York City, medically guided consultations help determine whether XERF belongs in a personalized approach to skin rejuvenation.

XERF vs. Thermage vs. Ultherapy: How They Compare
XERF and Thermage use monopolar radiofrequency energy to heat tissue and support collagen remodeling, while Ultherapy uses microfocused ultrasound with visualization to target selected tissue depths. XERF uses dual-frequency RF technology (6.78 MHz and 2 MHz), while Thermage FLX uses a single RF frequency of approximately 6.78 MHz. Ultherapy can target specific depths, including 1.5, 3.0 and 4.5 mm, depending on the treatment area and protocol. All three are non-surgical options for selected skin-laxity concerns, but they differ in energy delivery, comfort, clinical evidence and treatment planning. No device is universally best; the right choice depends on your anatomy, skin laxity, goals and medical evaluation.

Why the DEJ Holds the Secret to Younger Skin
The dermal-epidermal junction (DEJ) is the structural foundation where the epidermis meets the dermis, and its deterioration drives visible aging. Clinical biopsy data from a 63-year-old male patient treated with E-50 Skin Booster after microneedling showed a 17% increase in rete ridge density, 52% increase in epidermal thickness, and 61% increase in basal keratinocyte density, demonstrating that targeted exosome delivery can restore the DEJ architecture that gives skin its density and firmness.
