What is Red Light Therapy?

Red light therapy, also known as photobiomodulation or low-level laser therapy (LLLT), involves exposing the skin to red and near-infrared light for a variety of potential benefits. Red light therapy devices emit light at wavelengths ranging from 630-950nm. This red to near-infrared spectrum penetrates tissue deeper than other visible light and has positive effects on skin cells.

Red light therapy can be administered alone or in combination with other skin treatments like microneedling. Handheld at-home red light therapy devices are now available, but in-office treatments administered by a dermatologist or esthetician are more powerful and tend to use a combination of red and near-infrared wavelengths for enhanced results.

How Red Light Therapy Rejuvenates The Skin?

Red light therapy works by using wavelengths of natural red and near-infrared light to stimulate a biological response in skin cells. Some key ways red light rejuvenates the skin include:

  • Increased Cellular Energy: The light is absorbed by mitochondria in skin cells and helps increase adenosine triphosphate (ATP) production. This provides cells with more energy and boosts basic cellular functions.
  • Improved Blood Circulation: By increasing cellular activity, red light therapy improves blood flow in the small blood vessels of the face. Better circulation delivers more oxygen and nutrients.
  • Collagen Production: Red light exposure stimulates fibroblasts to produce more collagen and elastin, which are proteins that provide structure and elasticity in skin.
  • Reduced Inflammation: The light has an anti-inflammatory effect that helps calm irritation and redness on the skin’s surface. This helps reduce acne breakouts.

So in summary, red light therapy aims to create healthier, rejuvenated skin from the inside out by energizing cells, improving blood flow, and stimulating collagen. This is meant to have an overall anti-aging effect.

The Many Benefits of Red Light Therapy for Skin

So what exactly will consistent red light therapy sessions do for your skin? The benefits are numerous! Here are some of the top reasons to make red light a regular part of your skincare routine:

  • Smoother, firmer, more youthful skin texture
  • Reduction of fine lines, wrinkles and crow’s feet
  • Strengthen skin barrier function
  • Reduce enlarged pores
  • Decrease puffiness and under eye circles
  • Fading of sun/age spots and hyperpigmentation
  • Decreased redness and inflammation
  • Improved moisture retention and hydration
  • Treatment of acne and acne scarring
  • Accelerated healing of wounds or scars
  • Overall more radiant, youthful complexion

These benefits are said to be achieved through consistent use of professional red light therapy treatments or at-home LED light therapy masks and devices. Proponents claim results can become visible in as little as 4-6 weeks, with optimal results after 12 weeks or more of consistent treatments.

Research Supports red light therapy for rejuvenate skin

While red light therapy has become popular in skincare, what does the research have to say about its rejuvenating benefits? Here’s a look at some key studies:

  • A 2009 study found a significant increase in collagen production and an improvement in skin appearance after 11 sessions of red light therapy
    Multiple studies have proven that red light can smooth lines/wrinkles, shrink pores, and improve skin texture and radiance.
  • A 2014 study found that red light therapy can speed wound healing outside the body.
  • In a 2017 study, subjects who received red light therapy experienced significant improvements in hyperpigmentation.
  • In a 2021 study, patients with mild to severe acne experienced a significant reduction in inflammatory acne lesions after six red light treatments without any adverse effects

Clearly the science strongly supports incorporating red light therapy into your skincare routine to rejuvenate your complexion and achieve glowing, youthful skin!

Are There Any Risks or Side Effects?

A major perk of red light therapy is the lack of adverse side effects. Red light is a completely natural wavelength that your body responds to favorably. Unlike lasers that burn the skin, red light provides pure warmth and healing. There is no pain, peeling, or downtime. For optimal results, use your red light device as directed and don’t exceed recommended treatment times. With proper use, red light only activates beneficial skin cell pathways for collagen regeneration and renewal.

At-Home vs In-Office Red Light Therapy Treatments

Now that you know the science behind how red light revitalizes skin, you’re probably eager to start treatment! You have two main options for reaping the benefits of red light: professional treatments at a dermatology or skincare clinic, or convenient at-home treatments. Let’s compare the pros and cons:

Professional Red Light Therapy


  • Higher treatment power/energy for faster, more dramatic results
  • Large panel devices cover more surface area
  • Precise treatment wavelengths and parameters
  • In-office expertise and supervision


  • Very expensive per treatment
  • Inconvenient to travel to appointments
  • Less customizable sessions

At-Home Red Light Therapy


  • Affordable devices to own
  • Treatment anytime at your convenience
  • Customizable parameters to suit your needs
  • Can treat your entire body
  • Ongoing unlimited treatments


  • Lower power so results take longer
  • Smaller treatment areas
  • You manage your own treatment protocol

The choice between professional or at-home treatments depends on your budget, convenience, skin concerns, and how fast you want results. Many people find at-home red light therapy a cost-effective way to safely maintain their skin’s youthfulness as part of their regular beauty regimen.

Do At-Home Red Light Devices Really Work?

At-home red light therapy devices have exploded in availability and popularity in recent years thanks to their lower cost and convenience factor. But with so many products flooding the market, how can you know which actually work? After extensive research, I recommend considering devices from Reddot LED when shopping for red light therapy panels. Here’s why:

  • Precise Wavelengths – RedDot LEDs emit light at exact wavelengths optimized for absorption by cells – 660 nm (red) and 850 nm (near infrared).
  • Power Density – RedDot LEDs maximize power density, meaning they deliver higher intensity light in a focused beam for enhanced penetration into the skin. This translates to better results compared to panels with lower power density.
  • Full Coverage – RedDot LED panels that treat the entire face will be most effective for anti-aging benefits and skin rejuvenation. Spot treatment wands have limited use.
  • FDA Approved – RedDot LED products are FDA approved and have passed safety testing requirements.
  • 3 Year Warranty – A 3-year warranty provides peace of mind that your investment is protected. The company stands behind their product quality.

In conclusion, red light therapy shows significant promise as a non-invasive, natural way to rejuvenate aging skin and promote a more youthful complexion. Take control of your skincare by harnessing the power of red light today. Your skin will thank you for it. Don’t wait, order an RedDot LED device now and see the astonishing results for yourself!
