Skincare has become an essential part of our daily routine, and with so many treatments available, it can be challenging to find the one that suits our skin best. 

Red light therapy has been taking the skincare community by storm; and for good reason. This treatment, once only available in clinical settings, is now accessible from the comfort of your own home.


At its core, red light therapy uses tiny LED bulbs to emit red and/or near-infrared light into the skin. It can come in the form of a panel, which is found in professional settings, or portable masks for at-home use. 

When the red and near-infrared light is applied to the skin, it works by stimulating the mitochondria within each skin cell, giving the cells more energy. With this newfound energy, the skin can better repair itself, leading to increased collagen and elastin production, reduced inflammation and redness, and plumper, firmer, more youthful-looking skin.

Here are five reasons why red light therapy should be your go-to skincare treatment:

It has a multitude of anti-aging benefits

Red light therapy is known for its anti-aging benefits. By stimulating fibroblast cells, it reduces fine lines and wrinkles and may help improve sun spots by unifying skin tone and texture. It also boosts cellular energy, helping cells to grow and repair themselves, leading to plumper, healthier, and younger-looking skin. 

Red light therapy is also a great treatment alongside other cosmetic procedures, like Botox, microneedling, lasers, and fillers, as it can significantly reduce downtime after these procedures by decreasing bruising and swelling. It’s perfectly safe when used in conjunction with other treatments.

It soothes inflammatory skin conditions and decreases inflammation

Red light therapy is a popular choice among many for its ability to soothe inflammatory skin conditions like eczema, rosacea, and psoriasis. It can also be used to treat chronic inflammation, aid in wound healing, and can even provide relief from joint pain, such as arthritis. Red light therapy works by decreasing chronic inflammation present in the body and helps increase blood flow to damaged tissue. This helps to soothe the skin, while reducing symptoms like itching, burning, pronounced redness, and dryness. Unlike other popular treatments, red light therapy helps to heal the skin barrier from the inside out. Treating deep within the tissue makes for long-lasting results.

It reduces visible signs of sun damage

Red light therapy helps to drastically improve the skin’s appearance by kicking your cells into high gear to accelerate the healing process. When red and near-infrared light is absorbed into the skin, the mitochondria (your skin cell’s battery) is able to convert the light into energy. This creates a cascade of biochemical reactions like increased collagen and elastin production. The result? Calmer, firmer, more balanced, glowing skin.

It’s the #1 treatment for sensitive skin

One of red light therapy’s best qualities, compared to other cosmetic treatments like chemical peels or microneedling, is that it’s fabulous for sensitive skin! One-hundred percent natural, red light is responsible for reducing inflammation and sensitivity-related redness. 

What sets red light therapy apart is that it utilizes the skin’s own healing process to strengthen itself from the inside out. This FDA-cleared treatment helps to fortify the skin barrier to ensure skin health for the long haul.

It's 100% natural

Red light therapy is a totally natural, non-invasive treatment that produces noticeable results. This makes it ideal for those wanting to take a more holistic approach to their anti-aging oracne-clearing journeys, or for those looking to combine more aggressive therapies (like chemical peels, lasers, or dermal fillers) with a gentle, safe, and effective complementary treatment.



Red light therapy works by emitting low-level wavelengths of red and near-infrared light that penetrate the skin at various depths. These wavelengths of light are absorbed by the skin cells' mitochondria, which are often referred to as the "powerhouses" of the cells. This absorption of light energy stimulates the production of adenosine triphosphate (ATP), the primary source of cellular energy.

Increases the level of cellular energy.

When cells have increased levels of ATP, they are better equipped to perform vital functions, such as repairing damaged tissues, regenerating cells, and promoting the production of collagen and elastin. These proteins are essential for maintaining skin's firmness, elasticity, and overall health. As a result, red light therapy helps to reduce signs of aging, decrease inflammation, and improve the appearance of various skin conditions.

Improves blood flow and cellular oxygenation.

Furthermore, red light therapy stimulates the release of nitric oxide, a naturally occurring molecule in the body that aids in increasing blood circulation. Improved blood flow ensures that oxygen and essential nutrients are effectively delivered to the skin cells, further promoting cell growth, tissue repair, and overall skin health.

In summary, red light therapy works by harnessing the power of specific wavelengths of light to boost cellular energy, stimulate collagen and elastin production, improve blood flow, and encourage the natural healing processes of the skin. This ultimately leads to healthier, more radiant, and youthful-looking skin.



With the availability of portable red light therapy devices, it has become easier than ever to experience the benefits of this treatment in the comfort of your own home. Here are some steps to guide you through the process:

Choose a device: 

When selecting a red light therapy device, consider the area you want to treat, your budget, and the desired intensity. There are handheld devices, masks, and full-body panels available at various price points.

Prepare your skin: 

For best results, clean your skin and remove any makeup or skincare products. This ensures that the light can penetrate your skin effectively.

Follow the instructions: 

Each device comes with specific instructions for use. Make sure to follow the recommended treatment time and distance from your skin. Some devices may require you to wear protective eyewear.

Consistency is key: 

Like with any skincare treatment, consistency is crucial. Most at-home red light therapy devices recommend using them daily or every other day for several weeks to see optimal results. As your skin improves, you can reduce the frequency of your treatments.



Q: How long does it take to see results from red light therapy?

A: The duration required to see visible results from red light therapy varies from person to person and depends on factors like the severity of the skin condition being treated, the type of device used, and the consistency of treatments. Some individuals may notice improvements within a few weeks, while others might take up to several months. However, patience and consistency are key to achieving the best results.

Q: Is red light therapy safe for all skin types?

A: Yes, red light therapy is generally safe for all skin types and tones. However, if you have a history of light sensitivity or are taking medications that increase your sensitivity to light, it's best to consult with a healthcare professional before starting red light therapy treatments.

Q: Can I use red light therapy while pregnant or breastfeeding?

A: While there is limited research on the safety of red light therapy during pregnancy and breastfeeding, it's best to consult with a healthcare professional before using red light therapy during these times.

Q: Are there any side effects of red light therapy?

A: Red light therapy is generally considered safe and non-invasive, with minimal side effects. However, some people may experience mild redness, irritation, or warmth in the treated area. These side effects are usually temporary and should subside shortly after treatment.



Red light therapy offers a multitude of benefits for various skin conditions and concerns. Its anti-aging, anti-inflammatory, and reparative properties make it a versatile and effective treatment for a wide range of skin types, including sensitive skin. With at-home devices becoming increasingly accessible, red light therapy has become an essential addition to modern skincare routines. So, if you're looking to improve your skin's appearance and overall health, red light therapy should undoubtedly be your go-to skincare treatment.
