Keep reading to learn all about this innovative approach to skincare and how it can help you achieve a healthy, radiant complexion.

What skin conditions are treated with light therapy?

What is Light Therapy?

Light therapy, also known as phototherapy or LED therapy, delivers beneficial wavelengths of light to the skin in order to treat various cosmetic skin concerns. It works on the principle that different colors of light have different effects on skin cells.

Specifically, light therapy makes use of LEDs (light emitting diodes) that emit light at very specific wavelengths and only target the top layers of the skin. This targeted approach makes LED light therapy gentler than many traditional skincare treatments like chemical peels or laser resurfacing.

Some of the most common lights used in light therapy for skincare include:

  • Blue light: Kills acne-causing bacteria on the skin and reduces inflammation.
  • Red light: Boosts collagen production, reduces fine lines and wrinkles, and improves skin tone/texture.
  • Near-infrared light: Encourages cellular renewal and regeneration for an overall rejuvenating effect.
  • Violet light: Calms redness and flushing from rosacea.
  • Green light: Fades hyperpigmentation spots and helps treat melasma.
  • Yellow light: Improves redness, sun damage, and overall skin health.

As you can see, each wavelength targets something different and can be customized to treat specific skin concerns.

Skin Conditions Improved by Light Therapy

Light therapy has proven effective at treating all kinds of skin concerns through its ability to target cellular processes. Here are some of the many skin conditions that can benefit from therapeutic wavelengths of light:


One of the most studied uses of light therapy is for reducing acne blemishes and breakouts. Blue light is frequently used for its antibacterial effects on p. acnes bacteria, while red light can decrease inflammation. With a series of in-office or at-home light therapy treatments, you can significantly improve inflammatory and non-inflammatory acne. Light therapy is also beneficial for acne scarring by smoothing and brightening the skin’s texture.


The flushing, redness, and irritation of rosacea can be difficult to manage. Studies have shown that light therapy offers a non-invasive way to calm symptoms and reduce facial redness. Violet light targets the dilation of blood vessels, while yellow light soothes overall redness and inflammation. Patients see a noticeable reduction in the intensity of rosacea flares and discomfort.

Wrinkles/Fine Lines

Collagen is the protein that keeps skin plump and supple. As we age, collagen breaks down faster than it can be replenished, causing wrinkles. Many studies have proven that red light boosts collagen synthesis, helping smooth out fine lines and wrinkles. It also improves facial contours for a more youthful, defined appearance.

Skin Texture/Tone

Dull, uneven, and rough skin tone can make you look older. Studies show that light therapy delivers energy to stimulate cellular renewal and regeneration for improved radiance. All wavelengths help even out skin tone, reduce visible pores, and restore a healthy glow. Your complexionwill appear noticeably smoother and brighter.


Dark spots and melasma can be stubborn to treat. However, green and yellow light therapy targets overproduction of melanin (pigment) at the source. This helps lighten brown spots, age spots, sun spots, melasma, and post-acne marks for a more uniform skin tone.


Picking, popping, and severe acne can lead to scarring. Light therapy helps repair this damage by reorganizing collagen distribution and increasing healthy collagen. This allows depressed scars to fill in and become smoother. Regular treatments also help blend away the discoloration of old scars.

Types of Light Therapy Systems

If you’re interested in trying light therapy for your skin, there are a few options for getting started. Light therapy is available through dermatology offices, medi-spas/aestheticians, or at-home devices. Here’s a look:

Professional Treatments

Your dermatologist or a licensed aesthetician can provide in-office light therapy. Professional devices deliver medical-grade light at higher intensities than home systems. This gives optimal results, especially for severe acne and wrinkles. It’s done under supervision for a customized experience.

However, in-office treatments can be time consuming with set appointments. They’re also costly since they’re not covered by insurance. You’ll pay $100-300 per session or purchase packages of 6-8 treatments. Some offices do offer more budget-friendly options.

At-Home Devices

Over-the-counter light therapy tools have surged in popularity for delivering professional-quality light in the convenience of home. Premium consumer brands like RedDot LED offer LED masks and panels suitable for all skin types.

These easy-to-use systems give you the freedom to treat your skin any time. They emit varying light colors/combinations depending on your skincare goals. Treatment times range 5-20 minutes. Although results may take longer than in-office lights, at-home devices provide added affordability and accessibility. Cost is generally $50-2000.

Who is Not Suitable for Light Therapy?

While light therapy is one of the safest skin treatments available today, there are a few contraindications to be aware of. People with the following conditions should speak with a dermatologist before trying light therapy:

  • Pregnant women – Hormonal changes make skin sensitive. Light therapy could cause irritation. Best to avoid it.
  • Photosensitive disorders – People with lupus, polymorphic light eruption, and other light-sensitive conditions can experience adverse reactions. Special precautions need to be taken.
  • People on photosensitizing drugs – Certain medications like antihistamines, anti-inflammatories, and antibiotics increase light sensitivity. Adjustments to therapy may be required.
  • History of skin cancer – Those previously diagnosed with melanoma and other skin cancers have a higher risk of cancers recurring with UV exposure.
  • People prone to herpes outbreaks – UV light can trigger oral and genital herpes breakouts. Anti-viral medication may be needed before light therapy.
  • People with eye conditions – Light sensitivity issues like lupus can damage the eyes. Protective eyewear must be worn.

While most people can safely use light therapy, have an expert evaluation done first. Your health history and skin condition will be reviewed to minimize risks and customize treatment. Certain precautions may be necessary.

How to Choose a Light Therapy device?

The growing interest in light therapy has led to many device options. But not all systems are created equal when it comes to effectiveness and safety. Here are tips for picking a legitimate, quality device:

  • Medical grade LEDs – Look for professional LED quality for precision wavelengths. Avoid cheaper LEDs that may emit harmful UV.
  • FDA cleared – Choosing an FDA cleared device ensures proper testing for safety and performance.
  • Correct light colors – Make sure the system offers the specific light colors to treat your skin concerns.
  • Adjustable settings – The device should allow you to adjust light intensity and session times for optimal benefits.
  • User-friendly – It should be easy and comfortable for at-home use without professional training needed.
  • Warranty – Select a product with at least a 1 year manufacturer’s warranty for added buyer protection.
  • Budget – Consider your budget but note you often get what you pay for in terms of light quality and durability.
