Blue Light Therapy


Blue light treatment is used to treat skin conditions or damages. It's a non-invasive therapy, which causes no pain.

This is also known as photodynamic treatment as it uses high-intensity light with photosynthesizing medicines to activate the effect of the therapy. The light is normally blue or violet, and it's regarded as an alternative treatment procedure for skin damage.

This therapy applies only to the skin parts where the light can reach. So, it's mostly used underneath the skin layer or at the surface.

What are the uses and purposes of blue light treatment?

Several clinical studies have suggested that this therapy can improve, and heal a few skin conditions like skin cancer, acne, fatigue, and even Parkinson's disease.

Prevents skin cancer and sun damage 

This light therapy is mostly used for malignant or premalignant cancerous growth on the skin, and to cure sun damage.

Blue light therapy is normally used to stop the metastasizing of cancerous growths, and in serious conditions like skin cancer, it removes the cancerous and precancerous skin lesions, so it doesn't spread to the other body parts.

People who are suffering from skin cancer are often treated with photodynamic treatment, as it uses photosynthesizing medicine that is applied to the skin and it reacts with the oxygen and kills the cancerous cells. It can also be utilized to destroy damaged blood cells or the immunity system.

Skincare and acne prevention

Other types of skin issues can be treated with blue light therapy, and one of the common skin problems is acne. The therapy is used to improve the texture of the skin and reduce the big oil glands which are also known as sebaceous hyperplasia. The treatment can remove acne scars, sunspots, and acne.

Treats depression

Other than the skin treatment, this light therapy is also used to treat depression, and mostly the major issues that include seasonal patterns, known as the SAD or seasonal affective disorder. This disorder often occurs with seasonal changes, like winter, staying a long time at home, or darker days. The symptoms can be cured by light.

The working procedure of blue light treatment

Blue light therapy takes less time, as it is done using the outpatient process. But the exception to this procedure is that it is mainly used for treating skin cancer.

When you visit a clinic the skin care professional or the dermatologist will take you to a darkened room, if they are using photosynthesizing medicines. Next, the specialist will apply for the medicine over the place that needs treatment.

If the specialist has used a medication topically on your skin, you need to keep it for several hours or days, so the skin can absorb the drugs. When the medication is applied to your skin, the therapist will advise you to stay indoors, and not expose your skin to the sun or any type of bright light; you have to keep your skin safe, as long as the medication is still on you.

While using the photodynamic treatment, the dermatologist will give you eye protection to wear, and they will apply blue light to the affected areas.

The therapy session can be seventeen to ninety minutes, and it will depend on the size of the skin area, and if the specialist has applied for photosynthesizing medicines. For instance, if a small area on the skin has been affected by cancer, the light will be applied for at least seventeen minutes.

People who are suffering from SAD or depression can have a blue light treatment device at home to get a cure for the symptoms or the recurring issue daily.

Is Blue light therapy effective? 

This treatment procedure is effective for skin issues, and it's useful when people with such conditions opt for repeated appointments to maintain the therapy. It usually takes:

  • Six to four therapy sessions for acne issues, and the maintenance it requires every six months appointments.
  • Four-to-one therapy for actinic keratosis, including yearly maintenance.

Blue light or photodynamic treatment is very beneficial for skin cancer lesions, and the photosynthesizing medicines offer a stronger reaction to the treatment.

This treatment is also good for treating depression, but you need to talk to your physician first to know about the light amount you should use.

What are the side effects of blue light treatment? 

Just after having the therapy, the skin may turn tender, swollen, and red; it can even have mild blisters or bruises, mainly when the drugs are applied. The treated skin can start to peel or form a crust, but this is the normal reaction to the treatment. The plus side of this therapy is, that people recover from the issues within one week, and the peeling of the skin goes away in three to two weeks. If in the therapy the doctor has used medicine, your skin will become very sensitive to light. Thus, you need to protect your skin from the sunlight, but fluorescent light will be fine, also sunscreen will not be effective, as it protects you from UV rays only.

If you are treated rightly, there will be no side effects from this therapy. Also, it's a non-invasive treatment, which causes no scars after the session, and your skin will be healed in a couple of days.

Possible complications and risks to this therapy

Blue light treatment is very safe, even if topical drugs aren't used. But due to the light, the skin can have blisters, and it should care for unless it can create an infection.

People with lupus, and porphyria should opt for this therapy. This is the condition of the blood that can create increased sensitivity to lights. You should avoid getting this treatment if you are allergic to porphyrins.

When this therapy is used to treat skin cancer, it can cause swelling, and breathing trouble. If you face such issues, you must get in touch with the doctor.

Bottom Line
