Treat Precancerous Lesions with Photodynamic Therapy in Houston, TX
Year-round sun exposure in Southeast Texas can cause actinic keratoses (AKs), also called precancerous skin spots. If left untreated, some of them can turn into squamous cell carcinoma, a potentially serious type of skin cancer.
To address these precancerous spots, Dr. Khanh “Connie” Nguyen offers photodynamic therapy in Houston, TX. It’s a modern, minimally-invasive treatment that targets precancerous cells while protecting the surrounding healthy skin. At Premier Derm Center, we treat the entire affected area to remove both visible spots and the damage.
What Are Precancerous Lesions
For people in Southeast Texas, sun damage is almost unavoidable. UV rays can damage the DNA in skin cells. This damage often shows up as actinic keratoses, rough, scaly patches that may feel like sandpaper or small “scabs” that never fully heal.
These lesions usually appear on areas most exposed to the sun, including:
- The face and forehead
- The scalp (especially in men with thinning hair)
- The tops of the ears
- The “V” of the neck and chest
- The backs of the hands and forearms
How We Perform Photodynamic Therapy for Precancerous Lesions
We have designed our PDT process to be efficient, comfortable, and very effective. When you come to our Houston clinic for Photodynamic Therapy, you can expect a smooth, professional experience focused on your safety and comfort. Our process includes:
Preparation and Application
We start by cleaning the treatment area to remove oils and dead skin so the medication can work better. If some spots are thicker, we may gently remove the surface so the medicine can reach deeper. Then, we apply the Levulan solution to the entire treatment area.
Incubation Period
After applying the medication, Our dermatologist leaves it for some time to soak into the precancerous cells. This is called the incubation period. Depending on the area and amount of sun damage, you will relax in our office for about 1 to 3 hours. During this time, the medication is being absorbed and preparing the damaged cells for light treatment.
Light Activation
Once incubation is complete, you are moved to our light therapy room. We use either blue or red light placed near the treatment area for about 16 minutes. The light activates the medication, which destroys the precancerous cells. To keep you comfortable, we use cooling fans and other techniques during this step.

What People Say About Us
Based on Google Reviews
I have been a patient of Dr Nguyen for 17 years. She is by far the best dermatologist in Houston. She takes her time and is never rushed. She provides detailed, understandable explanations for her diagnoses and treatment plans. She has taken care of my children’s skin care needs from elementary school and continuing into adulthood.

Dr. N is very kind and reassuring. I love conversing with her. She really knows her stuff too. She has made such a difference in my rosacea. I look at old pictures and I am amazed at how much better my skin looks now. Staff is also very professional. I highly recommend her. I drive all the way from Clear Lake City to see her.

Dr. Nguyen is the kind of dermatologist who can make even a conversation about a sebaceous cyst feel completely normal — and dare I say, educational. She was kind, quick, and incredibly knowledgeable. I came in with a couple of mysterious moles and one rebellious cyst, and she handled all three with the calm precision of someone who’s clearly seen worse.

Dr Nguyen is wonderful. She has spent hours helping me with a multitude of things. Shingles being one. She is willing to try new methods that helped me tremendously. Her kindness and dedication are a testament to her. I feel safe with her. She also, is doing hair treatments on me that are working miracles for my hair. And many other cosmetic procedures too. I’m so glad I found her ❤️

Frequently Asked Questions
How should I prepare for my PDT appointment?
Please arrive with a clean face and do not apply any moisturizer, sunscreen, or makeup before your visit. Because you will be with us for a few hours during the incubation period, we suggest bringing a book or tablet.
How many sessions will I need?
Many patients see noticeable improvement after just one session. For patients with more extensive sun damage, we might recommend a second treatment 4-8 weeks later.
What if I get a very strong reaction?
A strong reaction, such as heavy peeling or crusting, usually means the treatment successfully targeted a great amount of sun damage. While it may look intense at first, it often gives long-term results.
What products should I use after my PDT appointment?
We recommend using gentle, fragrance-free cleansers and simple moisturizers like Aquaphor or Vaseline to keep your skin hydrated. Avoid active skincare products such as retinols, vitamin C, or AHAs for at least two weeks after your treatment.
