Photodynamic Therapy (PDT) in Meridian, ID
Treat Sun Damage, Precancerous Lesions, and Acne with Photodynamic Therapy
Photodynamic therapy (PDT), also known as blue light therapy, is a non-surgical treatment that targets damaged or abnormal skin cells while preserving healthy surrounding tissue. At Boise Dermatology & Medspa, we use photodynamic therapy to treat actinic keratoses (precancerous lesions), sun damage, certain cases of acne, and improve the overall appearance of sun-damaged skin.
By combining a light-sensitive medication with a specialized blue light, PDT selectively destroys damaged skin cells and stimulates healthier skin to emerge.
How Does Photodynamic Therapy Work?
Photodynamic therapy uses two important components:
- A prescription photosensitizing solution applied to the skin
- A specialized blue light that activates the medication
During treatment, the photosensitizing solution is absorbed by abnormal or damaged skin cells. Once activated by blue light, the medication creates a reaction that destroys these targeted cells while minimizing damage to surrounding healthy tissue.
Over the following days and weeks, your body naturally removes the treated cells and replaces them with healthier skin.
What Conditions Can Photodynamic Therapy Treat?
Photodynamic therapy is commonly recommended for both medical and cosmetic skin concerns.
Actinic Keratoses (Precancerous Lesions)
One of the most common uses for PDT is treating actinic keratoses (AKs)—rough, scaly patches caused by years of sun exposure.
Because actinic keratoses can develop into squamous cell carcinoma if left untreated, early treatment is important. Photodynamic therapy treats visible lesions as well as microscopic sun damage that may not yet be visible.
Acne
Photodynamic therapy may help patients with mild to moderate acne by reducing oil gland activity and targeting acne-causing bacteria. It can be an excellent option for patients who have not responded well to traditional topical or oral medications.
Sun Damage and Skin Rejuvenation
In addition to treating precancerous lesions, PDT can improve the overall appearance of sun-damaged skin by helping reduce:
- Rough skin texture
- Sunspots and age spots
- Fine lines
- Uneven skin tone
- Redness associated with chronic sun damage
Many patients notice healthier, smoother, and brighter-looking skin after treatment.
What Happens During a Photodynamic Therapy Appointment?
Your visit begins with a consultation to determine whether photodynamic therapy is the right treatment for your skin concerns.
If you’re a good candidate, your provider will:
- Cleanse the treatment area.
- Apply the photosensitizing solution.
- Allow the medication to absorb into the skin for a prescribed period, which may range from one to several hours depending on your treatment plan.
- Activate the medication using a specialized blue light for several minutes.
During the light treatment, you may feel warmth, tingling, or mild stinging. Most patients tolerate the procedure well.
What Is Recovery Like?
After treatment, your skin will likely appear:
- Red
- Sensitive
- Tight
- Dry or flaky
These effects are temporary and are part of the normal healing process.
The most important part of recovery is strictly avoiding direct sunlight and bright indoor light for at least 48 hours after treatment. Your provider will also recommend gentle skincare products, moisturizer, and sunscreen as your skin heals.
Most redness and peeling gradually improve over one to three weeks.
How Many Treatments Will I Need?
The number of treatments depends on the condition being treated.
Some patients achieve excellent results with a single treatment, while others benefit from a series of treatments to completely address sun damage, actinic keratoses, or acne.
During your consultation, we’ll create a treatment plan tailored to your skin and long-term goals.

Frequently Asked Questions
Does photodynamic therapy hurt?
Most patients experience mild warmth, tingling, or stinging while the blue light is active. Any discomfort typically subsides shortly after treatment.
Why do I need to avoid sunlight afterward?
The photosensitizing medication remains active in your skin for a short period after treatment. Sunlight can activate the medication unexpectedly, causing increased redness, irritation, or discomfort. Avoiding direct sunlight for at least 48 hours is essential.
How long does it take to heal?
Most patients experience redness and peeling for several days, with complete healing occurring over one to three weeks depending on the treatment area.
Can photodynamic therapy prevent skin cancer?
Photodynamic therapy is commonly used to treat actinic keratoses, which are precancerous lesions. Treating these lesions helps reduce the risk of some developing into squamous cell carcinoma.
Can PDT be combined with other treatments?
Yes. Depending on your skin concerns, photodynamic therapy may be incorporated into a comprehensive treatment plan that includes cryotherapy, topical medications, acne treatments, or cosmetic procedures.
