5 Tips for Starting Phototherapy Treatment 

If you’re getting ready to begin phototherapy—whether at a clinic or with a home device—congratulations! You’re taking a positive step toward clearer, healthier skin. Like any treatment, a little preparation can go a long way in making sure it’s safe and effective. Here are five simple tips to help you get started with confidence.

1. Protect Your Eyes

One of the most important parts of treatment is wearing proper eye protection. The special light used in phototherapy can harm your eyes if they’re not shielded during a session. Regular sunglasses don’t offer enough protection, and they let light in around the edges. Be sure to use the UV-blocking goggles that come with your phototherapy device or are provided by your clinic.

If you’re using a home device, everyone in the room should wear protective eyewear, and it’s best to keep pets out during treatment for their safety, too.

2. Be Sun-Safe

While you’re in active treatment, your skin will be more sensitive to sunlight. Wear SPF 30 or higher sunscreen when you’re outside to avoid sunburns. But here’s an important reminder: Wash off any sunscreen or skincare products before your next treatment, since these can block the light that’s meant to help your skin.

Many moisturizers and makeup products also contain sunscreen, so double-check those labels and cleanse your skin before each session.

3. Stick to a Routine

Phototherapy works best when it’s done regularly. Try to follow a consistent schedule, whether your treatments are at home or in a clinic. Most people treat 3 to 4 times a week, with evenly spaced sessions.

Also, be mindful of what parts of your body are exposed during treatment. If you cover an area one day but leave it exposed the next, it could lead to uneven results—or even a burn. Wearing the same type of clothing (like a T-shirt with the same neckline) helps keep things consistent.

4. Don’t Skip Without Adjusting

If you miss more than a week of treatments, you may need to start back at a lower light dose or shorter treatment time. Your doctor can help guide you, but don’t just pick up where you left off—your skin may not be ready. Starting a bit slower helps avoid burns or irritation.

5. Keep Your Doctor in the Loop

If you start taking new medications—even over-the-counter ones—let your doctor know you’re doing phototherapy. Some drugs can make your skin more sensitive (or less sensitive) to light, which might affect your treatment plan. It’s always better to check and stay safe.

A Final Word

These tips are meant to help you feel prepared and confident as you begin phototherapy, but they don’t replace advice from your doctor. If you ever have questions or notice anything unusual with your skin, reach out to your healthcare provider right away.

Starting light therapy is an exciting step toward relief and results. Stay safe, stay consistent—and take pride in the care you’re giving your skin!
