Light Therapy for Acne: It’s Time for Results

Posted on November 29, 2021

Light therapy acne can get rid of many skin issues.

From making you look unsightly to lowering your self-confidence, acne has many terrible effects. However, one promising treatment can get rid of it― light therapy acne.

From actors to models, light therapy has shown promising results.

But what exactly is light therapy? What does it do? How long do the effects last?

In this article, I will talk about what light therapy is, the issues it can solve, and how long its effects last. I will also walk you through the entire light therapy acne process.

What is Light Therapy?

As its name implies, light therapy is a treatment that involves light. This light often comes in the form of LED (light-emitting diode).

Also known as LED therapy and phototherapy, the treatment involves a special mask that emits light.

There are two kinds of light therapy: blue light therapy and red light therapy. Both help treat acne. However, they have slight differences.

In addition, LED therapy or light therapy acne can utilize both red and blue light to treat skin problems.

Light therapy acne involves blue, red, or both lights.

Blue Light Therapy

Cosmetic practitioners often use blue light therapy to treat acne breakouts. This is because blue light’s wavelength has an antimicrobial effect. As a result, blue light becomes effective in killing bacteria that accumulate in the oil glands.

Since the accumulation of bacteria in your pores causes acne, blue light therapy addressed your breakouts.

In fact, a study revealed that 77% of people with acne who were treated using blue light therapy for five weeks experienced improvements.

Moreover, blue light therapy helps condition your skin. It gets rid of free radicals that aggravate the aging process. Blue light therapy also has anti-inflammatory effects, which decrease acne symptoms like redness.

Red Light Therapy

Cosmetic practitioners often use red light therapy to treat scars caused by wounds and acne. The treatment can also deal with signs of aging such as fine lines and wrinkles.

While red light therapy does not have the same antimicrobial effects as blue light therapy, the treatment can still be effective.

Moreover, red light therapy helps speed up the body’s healing process. The treatment also has anti-inflammatory features.

In particular, red light therapy works below the skin’s surface. By doing this, red light therapy soothes and helps repair your tissues. Hence, if a chronic condition causes your acne, red light therapy can greatly help you.

Skin Problems Light Therapy Solves

If you suffer from skin issues, light treatment can help. Here are the skin problems light therapy can solve:

1. Acne

Millions of people suffer from acne. It is a common skin condition where the pores get blocked by oil, hair, dead skin cells, and bacteria. As a result, the blockage results in whiteheads, blackheads, nodules, and other kinds of pimples.

Fortunately, light therapy can help get rid of acne. The treatment uses varying wavelengths of light to get rid of the bacteria that clogs your pores.

So, if you have been suffering from acne, go to a certified cosmetic doctor to have it treated using light therapy.

2. Fine Lines

A common sign of aging, fine lines are shallow lines on the surface of the skin. Often found around the eyes, on the forehead, and around the lips, fine lines do not go deep into the skin.

Many aging people suffer from fine lines. This hurts their confidence. However, fine lines can be treated using light therapy.

By stimulating the production of collagen, light therapy can make your skin smoother. This reduces the appearance of fine lines.

3. Wrinkles

Wrinkles are another common sign of aging. Unlike fine lines, wrinkles are deeply seated in the skin. In a sense, wrinkles are the advanced version of fine lines.

Since wrinkles start as fine lines, they appear like them― only deeper.

Fortunately, light therapy can help. By emitting light on your skin, phototherapy stimulates collagen. Collagen is a protein that supports your skin and maintains its smooth, youthful look. Hence, light therapy helps reduce the appearance of wrinkles.

4. Scars

Scars caused by wounds, acne, and other conditions have terrible effects.

For one, they can be permanent. They leave marks that will be there forever unless treated.

Scars also decrease your confidence. This affects your work performance and relationships.

Fortunately, light therapy can get rid of your scars. Whether these scars are caused by wounds, acne, or other conditions, light therapy greatly helps.

In addition, light therapy has anti-inflammatory effects. Therefore, it can also help prevent blisters that hurt.

5. Chronic Conditions

If you suffer from chronic skin conditions, light therapy can help. Chronic conditions that can be treated using light therapy include psoriasis and eczema.

Psoriasis, an inflammatory skin disease often affects the knees, scalp, nails, and elbows. On the other hand, eczema affects the outer layers of the skin. Also known as atopic dermatitis, eczema causes itching, swelling, and cracking.

How Long Do the Results of LED Light Therapy Last?

The longevity of the results of light therapy varies per patient. Some enjoy results for months. Others can enjoy the results for a year or more.

In general, the longevity of the results depends on how often you get the treatment. While the treatments have to be properly spaced out, more sessions often mean longer results.

However, only your cosmetic doctor can determine how often you should go under LED light therapy. Your age, health, sensitivity to light, and the severity of your skin condition influence how long and often you have to go through light therapy sessions.

If you want to know exactly how many sessions you need, book a consultation with me.

Light therapy acne’s results vary from one person to another.

Light therapy acne’s cost varies depending on location and the severity of the issue.

How Much Does an LED Light Facial Treatment Cost in the UK?

The cost of light therapy acne in the UK varies. It depends on a lot of factors including location, number of sessions needed, and the severity of the issue.

Top skin clinics in London often charge higher than other clinics. Clinics at Harley Street, London’s Cosmetic Hub, also tend to charge more than those in other locations.

However, getting light therapy from a high-end, reputable clinic ensures great results. Hence, your investment becomes worth it.

On average, one LED session cost at least £80 in the UK. The cost will go higher if you need more sessions. A severe condition and large target area will also make you spend more.

Before LED Face Light Therapy

While LED light therapy is not a surgical treatment, it comes with some risks. Hence, you need to consult a cosmetic doctor before getting the treatment. You can book a consultation with me here.

During the consultation, I will ask about your goals. I will ask exactly why you want to have light therapy. I will also ask about your expectations.

Then, we will discuss your current condition, medication, and medical history.

Based on the information you will disclose, I will tell you whether you are an ideal candidate for light therapy. Sometimes, LED therapy becomes an adjunctive treatment. This means that I might suggest you go through other procedures such as non-surgical facelift and tear trough dermal filler treatment.

Once we set your customised treatment plan, you can schedule your first session.

Light therapy acne does not involve surgery, so it does not hurt.

During Light Therapy Acne

Light treatment is a non-invasive procedure, so it will not take long. On average, one session of LED light therapy for the face lasts for 20 minutes. The procedure will take longer if the target area is bigger.

LED therapy also usually does not involve topical anaesthesia. Despite this, you will experience minimal to no pain.

During a light therapy session, you have to sit first. A cosmetic practitioner will then place the LED mask on your face. After the treatment, the cosmetic practitioner will then remove the mask from your face.

Right after the treatment, your cosmetic doctor will give you some instructions. Make sure to follow them closely.

After Light Therapy

Light therapy does not require an overnight stay. Thus, you can go home after the treatment. However, you must take care of yourself after the session.

For one, you have to stay indoors for 24 to 48 hours after the treatment, or as directed by your doctor. You also have to avoid direct sunlight for a few days after the treatment.

You might also have to avoid some activities depending on the condition you got treated for. Your doctor will give you the list of activities you must avoid.

Lastly, if you experience any pain after the procedure, your doctor can prescribe painkillers.


Light therapy effectively treats mild to moderate acne. It can also treat mild to moderate cases of scarring. However, light therapy acne becomes more effective in treating severe cases when used with other treatments such as a vitamin drip and oxygen therapy.
