Red light therapy (RLT) has become a popular treatment for skin rejuvenation, acne reduction, and anti-aging, but many people wonder: Is it safe for the face?
The good news is that red light therapy is generally safe, non-invasive, and UV-free, but like any treatment, it can have minor side effects in some cases.
How Red Light Therapy Works
Red light therapy uses red (620–700 nm) and near-infrared (700–1100 nm) light to penetrate skin cells. This light stimulates collagen production, improves circulation, and supports cellular repair — all without heat or harmful UV exposure.
Possible Side Effects on the Face
-
Mild Redness or Warmth
-
Some users experience temporary pinkness or warmth on the skin immediately after treatment.
-
This usually fades within a few hours.
-
-
Dryness or Flakiness
-
Increased cellular activity can sometimes lead to temporary dryness.
-
Using a hydrating moisturizer after sessions can prevent this.
-
-
Eye Sensitivity
-
Although RLT is safe, looking directly at bright devices can cause eye discomfort.
-
Always use protective goggles or close eyes during facial sessions.
-
-
Mild Breakouts
-
Rarely, people with acne-prone skin may experience a temporary breakout as the skin purges toxins.
-
This usually improves with continued sessions.
-
-
Overuse Risks
-
Too many sessions in a short time may lead to skin irritation or overstimulation.
-
Follow manufacturer or professional guidelines: typically 2–5 sessions per week is recommended.
-
How to Minimize Risks
-
Start with shorter sessions (5–10 minutes) to see how your skin reacts.
-
Use eye protection if targeting the facial area.
-
Keep skin clean and moisturized before and after treatments.
-
Consult a dermatologist if you have sensitive skin, rosacea, or severe acne.
