LED Light Therapy
LED (light-emitting diode) therapy uses specific wavelengths of red and near-infrared light to support collagen synthesis, reduce inflammation, and improve skin health at the cellular level. It is a non-invasive, painless treatment with no downtime — used as a standalone session or as a complement to other procedures.
What LED light therapy is
LED light therapy uses photobiomodulation — the delivery of specific, non-thermal wavelengths of light energy to skin tissue. Different wavelengths penetrate the skin at different depths and produce different biological effects. Red light (approximately 630 to 660 nm) targets the epidermis and upper dermis to stimulate fibroblast activity and collagen production and reduce surface inflammation. Near-infrared light (approximately 800 to 850 nm) penetrates more deeply to support tissue repair and reduce deeper inflammatory processes. Unlike laser treatments, LED does not cause thermal damage.
What LED light therapy can address
LED therapy is used to support collagen synthesis and reduce early signs of skin aging, reduce redness and inflammation in reactive or post-procedure skin, support wound healing and recovery after microneedling, peels, or other procedures, improve overall skin quality and tone, and reduce acne-related inflammation (with blue light protocols where indicated). It is a supportive and adjunctive treatment, not a primary corrective procedure for significant structural concerns.
Who may be a candidate
Adults seeking a low-risk, no-downtime skin support treatment — particularly those with sensitive or reactive skin, those in recovery from other procedures, or those building a comprehensive skin health protocol. LED is one of the most broadly tolerated aesthetic treatments and is appropriate across all skin tones and most skin types. Candidacy is reviewed at consultation.
Who should avoid or delay treatment
LED therapy is not appropriate for patients who have active photosensitivity disorders (lupus, porphyria, xeroderma pigmentosum), are taking photosensitizing medications (certain antibiotics, retinoids, some acne medications — discuss at consultation), have active epilepsy (due to flickering light), have uncontrolled thyroid conditions (if near-IR is applied to the neck), or are pregnant (caution for abdominal application; discuss with your provider). It is also not applied over areas of active cancer or suspicious lesions. Eye protection is required during all sessions.
What to expect during a session
The skin is cleansed and protective goggles are applied. An LED panel or device is positioned over the face (or targeted area) at a prescribed distance and duration — typically 10 to 20 minutes per session. There is no discomfort; most patients experience mild warmth. There is no UV light involved. Sessions are often combined with other treatments (delivered after microneedling, peels, or injectables) to support recovery, or scheduled as standalone maintenance appointments.
Recovery and downtime
There is no downtime. Patients can resume all normal activities immediately after treatment. Skin may appear temporarily flushed for 30 to 60 minutes in some patients. Apply SPF 30 or higher as part of your daily routine. LED therapy does not create photosensitivity on its own.
Risks and side effects
LED therapy at appropriate clinical parameters has a very favorable safety profile. Risks are primarily related to improper use, photosensitizing medications, or use in contraindicated conditions. Without eye protection, prolonged light exposure can cause eye strain or temporary vision effects — protective goggles are always used during treatment. Rarely, patients with unrecognized photosensitivity may develop a skin reaction. Results are gradual and subtle; LED is not a stand-in for more targeted corrective treatments.
Alternatives
Alternatives for collagen support and anti-inflammatory skin management include microneedling, PDRN therapy, PRF/PRP treatments, retinoid home protocols, and medical-grade topical antioxidants. LED is most valuable as a complement to these approaches rather than a replacement. It is one of the few skin treatments with no recovery period and suitable for use even in sensitive or reactive skin during active treatment protocols.
How long results last
The effects of LED therapy are cumulative and gradual. Individual sessions produce mild, transient improvements; a course of sessions (typically six to ten, two to three times per week) is needed to see meaningful change in collagen density and inflammatory tone. Maintenance sessions once or twice monthly are commonly recommended. Results vary based on individual skin condition, the wavelengths used, device parameters, and consistency of treatment.
When to contact us
Contact us if you develop unexpected skin redness, burning, or irritation during or after LED therapy, particularly if you are taking any medications not previously disclosed. If you develop a skin reaction you believe may be photosensitivity-related, contact us and your prescribing physician before your next session.
Clinical notice
Information on this page is educational and does not replace an in-person consultation. Treatments are recommended only after reviewing medical history, anatomy, goals, and clinical suitability. Results vary. Appropriate candidates are determined at the time of consultation.
If you experience severe swelling, vision changes, difficulty breathing, signs of vascular compromise, or another urgent symptom after treatment, seek emergency care immediately.
