What is photodynamic therapy for acne?

PDT photodynamic therapy for acne is a treatment method that makes use of a drug, known as photosensitizing agent or photosensitizer, and a special kind of light. Whenever photosensitizer are revealed to a particular wavelength of light, they create a type of oxygen that kills neighbouring cells. Each photosensitizer is triggered by light of a particular wavelength. This wavelength decides the distance of the light travelling within the body. Therefore, doctors make use of particular wavelengths and photosensitizers of lights to treat various parts of the body with PDT photodynamic therapy.

What sources of light are accessible, and how are they used?

The light sources for PDT includes light-emitting diodes (LEDs), intense pulsed light, laser light, red light, blue light and several other visible lights (consisting of natural sunlight). Photosensitizer medicines may become triggered by one or more than one kind of light. The optimal source of light based on the perfect wavelength for the specific drug employed as well as target tissues.

The source of light requires being applied directly to the aimed tissues for a suitable amount of time. For surface procedures, the light is applied directly to the part of the skin where the photosensitizer medicine has been used (like arms, scalp, face etc.) for inside cancers, supplying the light to the needed area is more difficult. The light may be supplied via small fiber-optic wires within the body cavity or body part being treated. At times, endoscopes ( an elongated, lighted and thin tube that is placed within the body) are employed to supply the light into the  bladder, stomach, or lungs.

What kinds of cancer are presently treated with PDT?

By now, the FDA has permitted the photosensitizing component known as the Photofrin or porfimer sodium for use in PDT photodynamic therapy for treatment or ease the signs of non-small cell lung cancer and esophageal. Porfimer sodium is permitted to ease the signs of  esophageal cancer whenever the cancer blocks the esophagus or whenever the cancer can’t be suitably treated just by laser therapy. Porfimer sodium is employed to for the treatment of non-small cell-lung cancer in people for whom the normal procedure are not suitable, and to ease signs in patients who are suffering from non-small cell-lung cancer that blocks the airways. In the year of 2003, the FDA permitted porfimer sodium to treat precancerous lesions in people who have Barrett esophagus, a medical condition that can cause esophageal cancer.

Are there any side effects or complications of PDT?

Porfimer sodium helps to make the eyes and skin susceptible to light for about six weeks after the procedure. Therefore, patients are suggested to ignore the bright indoor light and direct sunlight for minimum of six weeks. Photosensitizers have a tendency to develop in tumors and the triggering light is aimed on the tumor. Consequently, there is a less chance to harm to healthy tissue. But, PDT photodynamic therapy can lead to scarring, pain, swelling, and burns in surrounding healthy tissue. Some other side effects are associated to the body part that is already treated. They can comprise shortness of breath, painful breathing, stomach pain, trouble swallowing, coughing etc.

PDT photodynamic acne  therapy  by using a non-side-effect photosensitizer that works with Omega LED light source to treat acne. It is called PDT photodynamic therapy. PDT GEL is a new concept of PDT acne treatment compared to traditional ALA-based photosensitizers, which use the skin protein component tryptophan to kill bacteria and release by-product amino acids. No burns, no pain, no tanning, no side effects! Now you can experience PDT photodynamic therapy for effective treatment of acne. In addition to the face, PDT gel can also be used on the back or anywhere on your body. Without the need for cumbersome application with MTS electric micro-needle, you don’t need to reconcile the product to consume a lot of time. All you have to do is to apply PDT gel on the skin of the patient along with the Omega LED light source. You can treat your patient’s face or body, as long as there is acne problem. The treatment time is faster and more convenient!

Photodynamic therapy (PDT), sometimes called photochemotherapy, is a light therapy involving light and photosensitizers. PDT has been proven to kill microbial cells, including bacteria, fungi and viruses. PDT skin is widely used to treat acne problems. This treatment is especially useful in cases of severe acne that do not respond to other treatments. PDT acne treatment also has effects on other skin conditions such as sunburned skin, precancerous cells and skin infections. PDT Photodynamic Therapy also reduces the size and activity of oil-producing glands on the skin, called the sebaceous glands. Excessive activity and inflammation of these glands can cause more severe acne. PDT photodynamic therapy is often more effective for inflammatory acne than non-inflammatory acne.

New concept PDT GEL riboflavin and tryptophan treatment principle

Photosensitizer is very important in PDT photodynamic therapy

1. Riboflavin activates tryptophan after exposure to blue light to form active free radicals.

2. Active radicals react with water molecules to produce ROS

3. ROS has the effect of reducing the secretion of acne bacteria and sebum

4. After the influence of tryptophan, by-products rapidly decompose as amino acids are discharged through metabolic pathways in the skin.

5. It does not cause any side effects, no need to worry about redness, burning or tanning

 

Why not use chlorophyll ALA aminolevulinic acid component of photosensitizer?

5-Aminolevulinic acid (ALA), an endogenous biochemical substance produced by ALA dehydratase and a series of enzymatic actions to produce protoporphyrin IX (PPIX) with strong photosensitivity. The synthesis speed of PPIX depends on the picking speed of this product, and this product is regulated by the feedback of free hemoglobin concentration. The exogenous product can bypass the feedback inhibition system and make the cells synthesize a sufficient amount of PPIX. The acne containing PPIX is irradiated with 420-640 nm light, and singlet oxygen (-O2) is generated during energy transfer. When the oxygen reaches a certain concentration, cell death (phototoxicity) can be induced.

Side effects: When treated with ALA, there is no selective destruction of normal tissues around it, such as oxidized proteins, liposomes and other subcutaneous cell structures. Oxygen free radicals generated under the pathological conditions of this product overload will lead to Acute periodic porphyria. In addition, this product will cause the release of iron ions in ferritin. Which will aggravate the oxidation of cells, it will lead to acute periodic porphyria. Some people will have erythema and swelling. ALA aminolevulinic acid also causes pigmentation, which is an anti-black phenomenon in some people during the treatment.

PDT photodynamic acne therapy usually takes 3 to 5 sessions for a complete treatment, depending on the skin condition of each patient. Each treatment interval is one week, but can be adjusted according to the patient’s skin condition. You can perform other skin treatment when doing PDT photodynamic therapy.
