What Does Red Light Therapy Do for Skin?

Red light therapy is making waves in the skincare world, and for good reason. Backed by science and trusted by professionals, it’s become a go-to solution for clearer, firmer, and more radiant skin. But what does red light therapy do for skin, exactly?

In this guide, we’ll break down how red light therapy works, the proven benefits for your skin, and why it’s quickly becoming a staple in at-home and clinical skincare routines alike.

What Is Red Light Therapy?

Red light therapy (RLT), sometimes called low-level light therapy (LLLT) or photobiomodulation (PBM), is a non-invasive treatment that exposes the skin to low levels of red or near-infrared light. This light penetrates the skin's layers to stimulate energy production at a cellular level.

Unlike ultraviolet (UV) rays, which can damage the skin, red light is safe, painless, and does not burn. It simply boosts your body’s natural ability to heal and regenerate.

How Does Red Light Therapy Work?

Red light therapy uses wavelengths in the 620 to 750 nanometre (nm) range. These wavelengths penetrate the skin and are absorbed by the mitochondria—the “powerhouses” of your cells. Once stimulated, the mitochondria produce more adenosine triphosphate (ATP), which fuels cellular activity.

In simple terms? Red light therapy gives your skin cells more energy to:

  • Repair damage

  • Produce collagen

  • Increase circulation

  • Reduce inflammation

These biological processes are the foundation for healthier, younger-looking skin.

What Does Red Light Therapy Do for Skin?

Let’s get to the core question: what does red light therapy do for skin? Here are the top skin benefits, supported by research and thousands of glowing user reviews.

1. Boosts Collagen and Elastin Production

Collagen is the protein responsible for keeping your skin plump, smooth, and youthful. As we age, collagen production naturally slows, leading to wrinkles, sagging, and fine lines.

Red light therapy stimulates fibroblasts (the cells responsible for producing collagen and elastin), which leads to:

  • Firmer skin texture

  • Reduced wrinkles

  • More elasticity around the jaw, eyes, and forehead

Clinical studies have shown that consistent red light therapy sessions over 8–12 weeks can significantly improve collagen density and skin firmness.

2. Reduces Fine Lines and Wrinkles

One of the most sought-after benefits of red light therapy is anti-aging. By stimulating collagen and boosting blood circulation, red light helps smooth out crow’s feet, forehead creases, and smile lines.

In a 2014 study published in Photomedicine and Laser Surgery, participants who used red light therapy experienced visible wrinkle reduction and overall facial rejuvenation after just four weeks of treatment.

3. Improves Skin Tone and Texture

Red light therapy doesn’t just work on wrinkles—it also improves overall skin tone and texture. It reduces redness, balances pigmentation, and smooths rough patches.

This makes it ideal for treating:

  • Uneven skin tone

  • Post-acne marks

  • Dull complexion

  • Sun-damaged skin

By improving circulation and increasing oxygen flow, red light therapy leaves skin looking fresher, more radiant, and naturally glowing.

4. Fights Acne and Breakouts

If you’re wondering what does red light therapy do for acne-prone skin, the answer is promising. Red light therapy reduces inflammation and boosts healing, making it a great option for:

  • Active breakouts

  • Redness and irritation

  • Preventing future flare-ups

While blue light therapy targets acne-causing bacteria, red light soothes and supports the healing process. Many at-home LED masks, including those offered by LED Skin Solutions, combine both blue and red light for a dual-action acne treatment.

5. Accelerates Wound and Scar Healing

Red light therapy speeds up the skin’s natural healing response. It’s often used to:

  • Minimise surgical scars

  • Heal wounds faster

  • Improve the appearance of stretch marks

  • Fade acne scars

Because it enhances blood flow and cell regeneration, RLT is a powerful tool in scar reduction and recovery care.

6. Reduces Inflammation and Redness

If you suffer from rosacea, eczema, or sensitive skin, red light therapy can help calm irritation. Its anti-inflammatory properties reduce swelling, soothe redness, and strengthen your skin barrier over time.

Many people report that regular use leads to less skin reactivity and a more balanced complexion overall.

How Often Should You Use Red Light Therapy?

Consistency is key.

For best results, experts recommend starting with 3–5 sessions per week for the first month. Each session should last between 10 to 20 minutes, depending on the area being treated.

After 4–6 weeks, you can maintain your results with 2–3 sessions per week.

At-home LED masks and handheld wands, like those from LED Skin Solutions, make it easy to integrate red light therapy into your daily skincare routine—no salon visits required.

Is Red Light Therapy Safe for All Skin Types?

Yes. One of the biggest advantages of red light therapy is that it’s:

  • Non-invasive

  • Chemical-free

  • Safe for all skin tones and types

  • Painless and comfortable

There are no known long-term side effects, and it can be used alongside other skincare products like serums and moisturisers.

That said, results can vary based on age, skin condition, and lifestyle. Always follow usage instructions, and if you have a medical skin condition, consult your doctor before beginning.

Who Should Try Red Light Therapy?

Red light therapy is suitable for almost anyone looking to improve their skin, especially those who struggle with:

  • Signs of ageing

  • Uneven skin tone

  • Acne or inflammation

  • Dull or tired skin

  • Scarring or stretch marks

Whether you're in your 20s looking to prevent ageing or in your 50s aiming to refresh your skin, red light therapy offers benefits at every stage.

Choosing the Right Red Light Therapy Device

Not all devices are created equal.

Look for an LED mask or wand that offers:

  • Wavelengths between 620–660nm (red) and 810–850nm (near-infrared)

  • Medical-grade LEDs

  • Comfortable fit for face or targeted areas

  • Hands-free options or adjustable timers for convenience
