Blue light therapy for acne is a relatively new form of treatment that uses a high intensity, (narrow blue band) fluorescent light source, which provides an even distribution of light, sometimes combined with a skin sensitizer called Levulan, that kills the P. acnes bacteria that clog skin pores and cause outbreaks of topical acne.
Mild acne patients are exposed to the blue light source in 15 to 30 minute sessions 2 to 3 times per week for 3 to 6 weeks, while more severe cases require the application of Levulan to the affected areas up to 60 minutes prior to blue light exposure (and may take a longer treatment period). Patients can either sit or lie down during treatment to maximize comfort.
Myth: Blue Light Therapy Is Not Safe
Fact: Blue light therapy has been approved by the Federal Drug Administration, but it is a relatively new treatment, therefore long term date is currently unavailable. Some dermatologists are concerned about the possibility of any light exposure aging and damaging the skin, which may make it more susceptible to skin cancers, but there is currently no conclusive data to confirm this.
Myth: There Are No Side Effects of Blue Light Therapy
Fact: Some known side effects of blue light therapy may include dry skin, swelling, mild stinging, burning and discoloration after treatment. Though these are considered to be only mildly discomforting, in some extreme cases a patient may have an allergic reaction to the skin sensitizer Levulan. It is strongly recommended that all patients discuss the potential risks with their physician before undergoing any medical treatment.
Myth: Blue Light Therapy Takes a Long Time
Fact: The primary benefits of blue light therapy are that it is a non invasive procedure with little discomfort to patients, requires no strict preparation prior to treatment or recovery period afterwards, causes minimal side effects, is gentle on the treated area and surrounding skin tissue and takes a relatively short period of time for results. Treatments can last from 15 to 30 minutes, and the patient is then free to resume her normal lifestyle, although she should avoid exposing the treated skin to excessive sunlight.
Myth: Blue Light Therapy Is Expensive
Fact: The cost of blue light therapy can range from $40 to $200 for a single session and from $1,000 to $2,000 for a full treatment, depending upon the severity of the acne.
Myth: Blue Light Therapy Can Leave Your Skin Prone to Sunburn
Fact: Blue light therapy may make skin more sensitive following treatment, so patients are advised to be cautious about sun exposure following the procedure.
Myth: Blue Light Therapy Requires Multiple Treatments
Fact: Results of blue light therapy will vary depending on the individual and the severity of the patient's acne. Some patients may experience results after one or two session, while others may require additional treatments before optimum results are achieved.
Myth: Acne Can Be Cured By Blue Light Therapy
Fact: Blue light therapy for acne is not a cure, but a treatment, one that depends on the severity of the patient’s acne.
