The Truth About Red Light Therapy: Can It Really Improve Your Skin?

Red light therapy has gone from niche to mainstream in recent years, touted for everything from smoothing fine lines to calming breakouts. But does it actually work—or is it just another overhyped trend?

Let’s take a closer look at what science really says about red light therapy, and when it might be worth exploring as part of your skincare or dermatology routine.

What Is Red Light Therapy?

Red light therapy (also called low-level laser therapy or photobiomodulation) uses specific wavelengths of red or near-infrared light to stimulate the skin and deeper tissues. Unlike UV rays, red light doesn’t burn or damage the skin. Instead, it works at a cellular level to boost energy production, reduce inflammation, and promote healing.

It’s used in dermatology for various skin concerns, and is even gaining traction in sports medicine and pain management for its anti-inflammatory effects.

How Does It Help the Skin?

1. Acne and Inflammation
   Red light therapy may help reduce acne by calming inflammation and supporting the skin’s repair processes. It doesn’t kill bacteria like blue light, but it can help soothe redness and speed healing in combination with other treatments.
2. Anti-Aging Support
   One of the most researched benefits of red light therapy is its effect on collagen production. Collagen is a protein that gives skin its firmness and elasticity—but it naturally declines with age. Red light has been shown in studies to stimulate fibroblasts (the cells that produce collagen), which can help improve skin texture, reduce fine lines, and enhance overall tone.
3. Wound Healing and Skin Recovery
   Red light therapy may accelerate wound healing and help minimize scarring. That’s one reason it’s sometimes used after microneedling, laser treatments, or even surgery—supporting the body’s natural healing process without introducing heat or trauma.

What Red Light Therapy Can’t Do

It’s important to have realistic expectations. While red light therapy can improve skin health, it’s not a miracle cure.

• It won’t replace sunscreen, retinoids, or professional treatments for severe acne, deep wrinkles, or pigmentation.
  
  
• It works best with consistent use—usually in a series of sessions over weeks or months.
  
  
• At-home devices may be convenient, but professional-grade treatments tend to deliver more reliable results due to higher intensity and precise dosing.
  
  

Is It Safe?

When administered correctly, red light therapy is considered safe for most skin types. It’s non-invasive, pain-free, and typically involves no downtime. However, those with certain conditions—like light sensitivity or active rashes—should consult a dermatologist first.

Should You Try It?

If you’re dealing with mild acne, sensitive skin, or early signs of aging—and want to explore non-invasive options—red light therapy might be worth trying. It's especially promising when combined with other dermatologist-recommended treatments and tailored to your unique skin goals.
