What Is Red Light Therapy, and What Can It Do for My Skin?

At Brillare Beauty Institute, we believe in teaching our students about the latest tools and techniques that can shape their careers—and red light therapy is one of them. Whether you’re a future esthetician or someone curious about skincare, let’s explore what red light therapy is, how it works, and if it’s right for you.

So, What Is Red Light Therapy?

Red light therapy is a non-invasive skincare treatment that uses low-wavelength red light to penetrate the skin’s surface and stimulate cellular repair. It’s also referred to as low-level laser therapy (LLLT) or photobiomodulation. Unlike UV rays, red light does not damage the skin—instead, it encourages cells to regenerate and function more efficiently.

Originally used in medical settings to help heal wounds and reduce inflammation, red light therapy has made its way into esthetics because of its noticeable effects on skin tone, texture, and signs of aging. It’s now a popular offering in both dermatology clinics and beauty schools alike.

How Does Red Light Therapy Work?

Red light therapy uses specific wavelengths—typically between 630 and 850 nanometers—that can penetrate the skin at different depths. Once absorbed, these wavelengths stimulate the mitochondria (a.k.a. the “powerhouse” of your cells) to produce more energy.

With that extra energy, your skin cells can:

Repair damage
Boost collagen and elastin production
Reduce inflammation
Promote healthier, smoother skin

In simpler terms, red light therapy gives your skin a boost so it can do what it does best—heal and glow.

The Benefits of Red Light Therapy

When used consistently and correctly, the benefits of red light therapy can be transformative for many skin types and concerns. Here are some of the most common benefits:

1. Improved Skin Texture and Tone

Red light therapy stimulates collagen production, which helps reduce the appearance of fine lines, wrinkles, and enlarged pores. Over time, the skin looks smoother and firmer.

2. Reduced Redness and Inflammation

Whether you’re dealing with acne, rosacea, or post-procedure irritation, red light therapy has a calming effect on the skin. It soothes inflammation and can reduce redness in sensitive or reactive skin.

3. Faster Healing

This therapy can help accelerate the skin’s natural healing process. It’s often used after more intensive treatments—like chemical peels or microneedling—to reduce downtime and improve recovery.

4. Less Acne

By reducing inflammation and stimulating cellular repair, red light therapy can help clear up acne-prone skin. While it doesn’t kill bacteria like blue light therapy does, it supports the skin’s ability to repair and regenerate.

5. Even Skin Tone and Radiance

Regular use can lead to brighter, more even skin. Many clients report a subtle “glow” after just a few sessions.

Is Red Light Therapy Safe?

Yes, when used properly. Unlike UV light (which can damage the skin), red light does not burn, harm, or increase the risk of skin cancer. It’s considered gentle and non-invasive, making it safe for most people when used with appropriate precautions. The light itself doesn’t hurt, and there’s no recovery time needed.

However, there are a few things to keep in mind:

Avoid Overuse: While red light therapy is gentle, more isn’t always better. Following recommended guidelines for frequency and duration is key.
Check for Photosensitivity: If you’re taking medications or have medical conditions that cause photosensitivity, check with your healthcare provider before starting treatment.
Use FDA-Cleared Devices: Not all devices are created equal. For home use, it’s important to use devices that are FDA-cleared and used according to manufacturer instructions.
Always Wear Sunscreen: While red light therapy doesn’t make your skin more sensitive to light like UV rays do, pairing it with daily sunscreen use is essential. Especially when using more intensive skincare treatments, sun protection helps maintain healthy skin and prevent damage.

Curious minds should also know that red light therapy has minimal side effects when performed correctly. Most people experience no discomfort at all—just a gentle warming sensation. However, here are a few possible side effects to be aware of:

Temporary redness or tightness (usually mild)
Eye strain if goggles aren’t worn
Irritation if combined with aggressive treatments (like retinoids or acids)

As always, it’s important to follow guidelines, wear sunscreen, use proper protection for the eyes, and space out treatments to avoid overstimulation.
