You can find many reviews, tips, and scientific evidence about the benefits of light therapy for our well-being.

Red light therapy technology

The basis of red light therapy is the science of photobiomodulation (PBM), which is a process by which light energy (specific wavelengths of red and near-infrared light) triggers positive changes at the cellular level.

PBM can promote collagen production, increase blood circulation and reduce inflammation. These benefits make red light therapy an attractive option for those who want to improve the appearance of their skin.

However, there are also some potential downsides, such as the risk of eye damage and skin irritation. Furthermore, it is important to note that red light therapy is not FDA approved for use on the face.

Red light therapy is an alternative to traditional medical treatments. In some cases, you may use it in addition to other remedies.

The pros of red light therapy for your face

Red light therapy can help improve the appearance of the skin in several ways. It can help reduce the appearance of fine lines and wrinkles and improve skin texture and elasticity. Red light therapy can also help reduce the appearance of dark spots, blemishes, and even your skin tone. Below you can learn about all advantages of RLT and its influence on the skin.

Cure several skin issues

LLLT is known worldwide as an alternative treatment for some skin diseases due to its deep penetration into tissues and promotes recovery and healing. What skin diseases does light therapy affect? Let’s describe them below:

Aging of the skin: Red light therapy treatments improve the appearance of fine lines, wrinkles, roughness, and laxity of the skin. It can decrease the signs of sun damage and other aging spots.

Acne: It is the most common skin problem for many people around the world. RLT can be effective in reducing inflammation. As a result, it reduces the number of breakouts and destroys the bacteria that cause acne. In addition, it can help even out skin tone, improve skin texture and reduce acne spots.

Red light therapy effectively treated psoriasis Vulgaris, a chronic skin condition characterized by itchy, scaly patches. It can significantly reduce itching and flaking as well as other annoying symptoms. Besides, it has fewer side effects in comparison with topical benzoyl peroxide.

And finally, red light therapy is effective in treating rosacea and eczema, chronic conditions that cause redness and inflammation of the skin.

Facial red light therapy is considered a relatively safe procedure with few side effects. It is generally well-tolerated, and you should feel comfortable. The risks are minimal, and the side effects are usually mild. Besides, if you use the light device correctly, there will be no side effects.

RLT is non-invasive

Facial red light therapy is a non-invasive, painless treatment that uses LED lights to boost collagen production and improve the appearance of your skin. No needles or surgery are involved, making it a popular choice for those who want to avoid more invasive procedures. The only thing that will touch your skin is the light itself.

You can do it at home

One of the pros of facial red light therapy is that you can do it at home. You don’t need to go to a salon or spa for this treatment. All you need is a device that emits red light.

  • You can find these devices online or in some stores.
  • They are not very expensive, and you can use them whenever possible.
  • You can find devices of all different sizes, so if you only want to treat your face, there are options. Or, you can get a full-body device and treat your whole body at once.
  • But it still requires commitment. You’ll need to use it regularly for several weeks or months to see results.

If you have sensitive skin, you may want to start with a lower setting on the device and work your way up. You should consult a dermatologist before using any new skincare product or treatment.

Several disadvantages of facial red light therapy

It is a relatively safe procedure. However, there are several drawbacks you should know about before using it as a skin treatment. It’s essential to consult with a doctor before starting facial red light therapy to make sure it’s right for you and to discuss any potential risks.

You need several sessions

Facial red light therapy requires several sessions before you see any results. It can be expensive and time-consuming, especially if you have to go to a professional.

On the plus side, each session is relatively short (usually around 20 minutes), so it’s not a huge time commitment. And once you start seeing results, you’ll only need maintenance treatments every few weeks or months.

It’s not appropriate for everyone

Facial red light therapy isn’t suitable for everyone. There are several contraindications not to using it:

  • If you have lupus or other autoimmune diseases.

  • If you have skin cancer.

No guarantee for positive results

Though the treatment is often touted as a panacea for various skin concerns, from wrinkles to acne, there is no scientific evidence to support these claims. More researches need to prove its effectiveness. Besides, positive results depend on the complexity of your skin condition.

Several side effects

One of the main risks of red light therapy for the face is eye damage. Since the treatment involves exposure to bright light, there is the potential for retinal damage. It will be better to protect your eyes during the procedure.
