Red Light Therapy for Better Skin – A Non-Invasive Treatment


Interested in how to use red light therapy for skin health? This comprehensive guide covers everything you need to know.

When it comes to achieving healthy and radiant skin, the beauty industry is constantly introducing new treatments and products. However, one innovative approach that has been gaining popularity in recent years is red light therapy.

Red light therapy, or RLT, involves directing red- or near-infrared light at the skin. This application of light triggers a cellular response. And this response is believed to help the skin naturally repair itself.

Red light therapy therefore offers potential rejuvenating effects on the skin, including reducing psoriasis symptoms and reducing cellulite.

In addition, research suggests that red light therapy may help address common skin concerns, such as discoloration, sun damage, and dark spots. Interested in how it works? This guide takes a closer look at this emerging therapy and how light therapy is used to improve skin health.

What Is Red Light Therapy: A Brief Overview

Red light therapy is a treatment that exposes the skin to low-level red or near-infrared light wavelengths. It is the most common form of photobiomodulation therapy.

Here’s a quick theory of how red light therapy for skin health works:

When using this therapy, the wavelengths of red light penetrate the skin’s surface, stimulating various cellular processes and promoting healing and rejuvenation.

Ultimately, photobiomodulation and red light therapy are booming in popularity. Today, many celebrities use it to promote healthier skin and reduce wrinkles.

How Does Red Light Therapy Work?

Red light therapy uses low-intensity red and near-infrared light that can improve the skin’s condition. Red light therapy may significantly show positive results on skin burns, wrinkles, black spots, scars, redness, and acne. It is also known to treat other medical bodily conditions.

Red light therapy is known to improve energy levels by strengthening mitochondria, the ‘power plants’ of your cells, which are responsible for creating energy. Researchers believe that red light therapy can stimulate the production of more ATP, which is responsible for storing and providing energy to the cells.

How Does Red Light Therapy Work for Skin?

Red light therapy may help improve skin as it stimulates collagen production, which helps strengthen skin elasticity, further reducing the signs of aging. RLT may also improve blood circulation, which can promote acne reduction and scar healing.

Targeted Solutions for Skin Concerns

There are numerous benefits of photobiomodulation and red light therapy. However, when it comes to skin health, this therapy may help treat sun damage and discoloration and reduce fine lines by stimulating collagen production.

Here’s a closer look at using red light therapy to treat various skin conditions:

1. Red Light Therapy for Sagging Skin

Sagging skin is a common occurrence with aging. Red light therapy stimulates the body’s natural collagen production processes to fight off sagging skin. The stimulation of collagen is responsible for skin structure and firmness.

There are a few reasons for sagging skin, such as:

  • Weight loss
  • Pregnancy
  • Lifestyle changes, such as smoking
  • Aging
  • Skin burns and sun damage

How does it work?

Red-light and near-infrared light wavelengths penetrate the skin, increasing collagen production and ultimately promoting skin tightening. This targets the sagging skin and pulls.

2. Red Light Therapy for Itchy Skin

Itchy skin generally causes discomfort, and excessive itchiness can cause severe damage to the skin.

Itchiness can be caused by:

  • Eczema
  • Psoriasis

Fortunately, research on red light therapy has shown a positive impact on reducing itchiness and associated inflammation. Simultaneously, the treatment helps in the quick healing process of the skin.

What is recommended?

  • It is recommended to incorporate regular sessions in your routine on a weekly basis.
  • It is crucial to continuously moisturize the skin to reduce discomfort and inflammation.
  • It is said that combining red light therapy with bathing therapy can be more beneficial.

Start with short sessions before increasing the duration depending on your skin’s response and reaction. Also, make sure the device is clean before use.

3. Red Light Therapy for Skin Tightening

Red light therapy helps with skin firmness, improves skin elasticity, and enhances skin complexion. A regular skincare routine along with sessions of red light therapy may help with skin tightening.

4. Red Light Therapy for Fading Dark Spots

Dark spots, also known as hyperpigmentation, can be a common and frustrating skincare concern. Whether caused by sun exposure, acne, or aging, these patches of discolored skin can significantly affect one’s confidence. Red light therapy offers an effective solution for fading dark spots and achieving a more even complexion.

The therapy works by targeting melanin-producing cells (melanocytes) in the skin. Melanin is responsible for skin pigmentation, and overactive melanocytes can lead to the formation of dark spots. Red light therapy for dark spots can help regulate melanin production, gradually reducing the appearance of dark spots.

Consistent use of red light therapy devices at home, such as specially designed PBM (photobiomodulation) therapy devices, can yield noticeable results over time. This non-invasive approach offers a gentle and natural way to combat stubborn dark spots that may have been bothering you for years.

5. Red Light Therapy for Skin Discoloration

Skin discoloration can occur for various reasons, including hormonal changes, skin conditions, and inflammation. Red light therapy for skin discoloration can be a valuable ally in correcting these uneven skin tones by promoting a more uniform complexion.

The therapy’s ability to increase blood circulation and stimulate cellular activity is particularly beneficial in addressing discoloration. Improved circulation ensures that oxygen and nutrients are efficiently delivered to the skin cells, aiding repair and regeneration.

Ultimately, it’s a non-invasive and safe option that complements your existing skincare routine.

6. Red Light Therapy for Dry and Sun-Damaged Skin

Excessive sun exposure and heat stroke can lead to various skin issues, including sunburn, premature aging, and even skin cancer. While sunscreen and protective clothing are essential for preventing sun damage, red light therapy can play a vital role in repairing the damage that has already occurred.

How? Red light therapy stimulates collagen production. This protein is crucial in maintaining the skin’s elasticity and firmness. Collagen production tends to decrease with age and is often reduced by UV radiation.

By promoting collagen synthesis, red light therapy may help reduce damage caused by heat, such as the appearance of fine lines and wrinkles.

In addition, red light therapy alleviates sunburn-related inflammation and redness, providing relief and aiding in the skin’s natural healing process. With regular PBM sessions, individuals can experience a visible improvement in their skin’s overall texture and tone, making it a valuable tool in the battle against sun-damaged skin.

7. Red Light Therapy for Reducing the Appearance of Fine Lines and Wrinkles

As we age, our body’s natural production of collagen and elastin decreases, developing fine lines and wrinkles. Red light therapy can effectively target this age-related concern by stimulating collagen production and enhancing skin elasticity.

When collagen levels increase, the skin becomes more supple and firm, reducing the depth and visibility of fine lines and wrinkles. This non-surgical, non-invasive approach is particularly appealing to those looking for natural ways to combat the signs of aging.

One trial from 2014 aimed to assess the efficacy and safety of polychromatic light therapy, including red and near-infrared light, in improving skin appearance and feel. A total of 136 participants underwent treatments with varying light sources and parameters, including red light and energizing light technology.

Results showed significant improvements in skin complexion, skin feeling, collagen density, skin roughness, and wrinkle reduction in the treatment groups compared to controls. Long-term follow-up also indicated sustained benefits.

The study suggests that non-invasive polychromatic light therapy can enhance skin rejuvenation and collagen synthesis, making it a promising option for skin care.

Holistic Skin Care with Red Light Therapy

While shifting our focus towards holistic skincare, here’s a look at how red light therapy can contribute to overall skin health:

1. Red Light Therapy for Skin Rejuvenation

A lot of research has explored the benefits of red light therapy for skin rejuvenation, and studies claim positive abilities, such as:

  • RLT encourages and stimulates the production of collagen; this protein is responsible for skin firmness and elasticity.
  • Elastin synthesis improves the skin’s texture, making it firm and resilient. Red light therapy supports the synthesis of elastin.
  • When red light therapy is exposed to the skin, it gets penetrated, further promoting increased blood flow. This improved blood circulation helps send oxygen and nutrients to skin cells, fostering better skin health.
  • RLT can reduce inflammation, skin irritation, and redness.

2. Red Light Therapy for Acne and Scars

RLT has shown promise in offering a non-invasive, painless, low-level red wavelength approach to addressing acne scars. A few of the key benefits of RLT for acne scars are:

  • RLT can help accelerate scar healing, making the skin clean, clear, and glowing.
  • Regular red light therapy sessions can help improve skin texture, as reduced scars and acne can contribute to much smoother skin.

3. Red Light Therapy for Aging Skin

RLT can reduce fine lines and wrinkles, making the skin look even and clean. Here are some of the benefits for aging skin:

  • When fine lines and wrinkles are reduced, RLT can aid in enhancing skin elasticity.
  • Red light therapy can reduce age spots and hyperpigmentation, creating a more uniform complexion.
