How Long Should You Do Red Light Therapy on Your Face?

If you’re new to red light therapy and want to know how long your facial sessions should last, you’re not alone. For optimal results and safety, most experts recommend the following:

Per session: 10–20 minutes
Frequency: 3–5 times per week to start
Consistency: Stick with the schedule for at least 4–8 weeks to see visible results

This guidance fits most at-home devices and professional treatments for facial rejuvenation, reducing fine lines, improving skin tone, and treating common concerns like acne or hyperpigmentation.[1][2]

Why 10–20 Minutes Is Ideal

The 10–20 minute session window allows enough time for therapeutic red and near-infrared wavelengths to penetrate the skin, triggering collagen production and cellular repair. Sessions shorter than 10 minutes often don’t provide enough stimulation for visible change, while longer than 20 minutes may lead to diminishing returns or skin sensitivity, without adding more benefit.[3][4]

Session Timing Recommendations for Common Skin Goals

Skin Goal	Session Duration	Frequency	Notes
Fine lines & wrinkles	10–20 min	3–5x per week	Move to once/week for maintenance after 2–3 months
Acne or inflammation	10–15 min	3–4x per week	Avoid overuse if skin becomes dry or irritated[1]
Hyperpigmentation / Spots	15–20 min	3–5x per week	Results may take 8–12 weeks to appear
Sensitive skin/rosacea	5–10 min	2–3x per week	Start with shorter sessions, increase slowly
[1][3]
Always check your device’s instructions and consult a dermatologist if you have specific concerns.

Key Steps for a Red Light Facial Session

Cleanse your face before each session.
Position the device 6–12 inches from your skin (adjust per manufacturer).
Wear eye protection if needed, especially for bright LED panels or masks.
Relax and time your session—start with 10 minutes.
Moisturize afterward to lock in hydration.
Track your progress: Take regular photos to note improvements.

What If You Use Red Light Therapy Too Long?

Using red light therapy on your face for longer than 20 minutes does not provide extra benefits and may increase the risk of irritation for sensitive users. The skin’s response follows what’s known as the “biphasic dose response”—meaning there’s an optimum dose and duration, and more is not always better.[3][5]

Expert Tips For Beginners

Start slow: Begin with fewer, shorter sessions and work up if no irritation occurs.
Stay consistent: Session regularity is more important than doing longer treatments.
Monitor response: Redness, dryness, or tingling are signs to decrease either duration or frequency.
Review device specs: High-powered devices may need less time; always check manufacturer guidelines.

Common Misconceptions

“The longer, the better”—False. Too much exposure does not speed up results and may slow progress.[3]
“Daily use is always best”—Unnecessary; 3–5 sessions a week is sufficient.
“All devices need 20 minutes”—Not true; follow your device’s instructions and adjust for power.

Summary

Most people should do red light therapy on the face for 10–20 minutes per session, 3–5 times a week, and stay consistent for at least 1–2 months for visible results. Start with shorter sessions if you’re new, and adjust based on your device and your skin’s needs.[1][3]
