Red Light vs Blue Light Therapy: What’s the Difference & Which Should You Use?

What is red light therapy?

Red light therapy uses low-level wavelengths in the visible red spectrum. It’s often used in wellness and beauty routines because it can support cellular energy, which in turn may help with:

  • A sense of muscle ease and post-activity comfort
  • Skin luminosity and smooth-looking texture
  • A general feeling of recovery after daily strain

Red light is popular for people who train, stand or sit for long periods, or want a calm, consistent at-home routine that supports how they move and feel.

Where red light fits in a daily routine?

  • After a workout or long day at a desk
  • Before evening wind-down, paired with gentle stretching
  • As part of a skincare ritual for a healthy-looking glow

On Ultrasonic PRO, choose 🔴 Red when your focus is muscle comfort and overall recovery.

What is blue light therapy?

Blue light therapy uses visible blue wavelengths that focus more on the skin’s surface. In wellness routines, it’s valued for a calming, clarifying effect and for supporting joint comfort when used consistently.

People often choose blue light when they want a fresher-feeling complexion or a soothing option for joints after daily activity.

Where blue light fits in a daily routine?

  • On days when joints feel taxed (after long walks, stairs, or training)
  • In morning routines to refresh the look/feel of skin
  • Between work blocks for a short, calming session

On Ultrasonic PRO, choose 🔵 Blue when your focus is joint calm and surface-level clarity.

Red vs Blue: how to choose?

  1. Muscles feel tight or taxed? → Start with 🔴 Red
  2. Joints feel sensitive or you want surface clarity? → Choose 🔵 Blue
  3. Unsure? → Try 3–5 minutes of one mode, then switch and notice which feels more supportive that day.

Tip: Consistency > intensity. Short, regular sessions create the best experience.

 

Safety basics:

  • Use on clean, dry skin.
  • Start with short sessions (3–5 minutes) and build gradually.
  • Avoid use on broken/irritated skin.
  • If you are photosensitive, pregnant, or have a medical device/condition, consult your clinician before use.
  • Eye care: Don’t stare directly into the light source and keep a sensible distance.

At-home best practices:

  • Stack your habits: Pair light therapy with something you already do—morning coffee, evening journal, or post-shower skincare.
  • Track your sessions: 3–5 minutes per area, up to 10–20 minutes total, 3–5× per week is a great place to start.
  • Keep it comfortable: The goal is a calm, soothing experience—not heat or intensity.
