Acne PDT in Homaesil: How should you spend the 48 hours after treatment?

For 48 hours after acne PDT, the medication remaining on your skin can react to light, so you need to avoid sunlight and strong lighting. Most daily activities are still fine, but if you're planning PDT in Homaesil, it's best to choose days when you can mainly stay indoors for those two days.

• The key for the 48 hours after treatment is blocking out sunlight and bright lighting.
• Redness, stinging, flaking, and temporary breakouts can occur.
• Start washing your face and applying makeup gently, from the time you're told you can.

Why do you need to avoid light for 48 hours after treatment?

PDT, or photodynamic therapy, involves applying a light-sensitive medication to the skin, waiting for a set time, and then exposing it to medical light energy. Even after the treatment ends, the medication remains in the skin for a while, so exposure to sunlight during that time can trigger a stronger reaction than intended.

That's why you're advised to avoid not only outdoor sunlight but also light coming through a window and very bright lighting for 48 hours after treatment. If this period isn't followed, redness and stinging can worsen, or pigmentation may remain.

Because there's time for the medication to sit and time for light exposure, the treatment itself takes around 1 to 2 hours. Since the treatment takes a while, deciding your route home and your schedule afterward in advance makes it easier to avoid light.

How do you block light on your way home and at home?

When you leave the clinic, cover your face completely with a wide-brimmed hat, mask, and sunglasses. If you're driving, use window sun shades, and if you're taking public transportation, it's best to avoid seats near the window.

• Block the sunlight from the window with curtains or blinds.
• During the day, stay away from the window rather than near it.
• Lower the brightness on your phone and monitor, and avoid holding them close to your face for long periods.
• Cover your face when going outside, even on cloudy days.

Sunscreen alone may not be enough to block light completely, so use physical coverings like a hat and mask together. At night, it's often fine to stay under your usual indoor lighting. However, please avoid placing a bright lamp close to your face or leaving a vanity mirror light on for a long time.

What reactions or side effects can occur while avoiding light?

During the procedure, you may feel a stinging or burning sensation, and afterward, redness and swelling can last for several days. Results and reactions vary by individual, and areas with more sebum and inflammation tend to show more noticeable reactions.

• Redness, warmth, and mild swelling can occur.
• Thin scabs and flaking skin may appear.
• Acne may temporarily flare up for a few days after the procedure.
• In rare cases, blisters, pigmentation, or severe swelling may occur.

The temporary breakout of acne usually appears within a few days after the procedure and then settles down. Squeezing or picking at it can leave marks, so leave it alone, and if more pus-filled spots appear, have the clinic check it. If blisters form or swelling becomes severe enough to make it hard to open your eyes, contact the clinic right away.

When can I wash my face, apply makeup, or go back to work?

Washing your face lightly with lukewarm water and a mild cleanser is often fine starting the evening of the procedure. Even if flaking occurs, don't rub or pick at it — apply enough moisturizer instead.

It's best to start wearing makeup lightly after the redness and stinging have settled down. If you work indoors, returning to work the next day is often possible, but if you sit near a window or go outside often for work, adjusting your schedule by about two days may be more comfortable.

Even if you're receiving multiple sessions, you need to follow the same 48-hour light-avoidance rule every time. If you set aside about two free days for each session from the start, your schedule will be less likely to be disrupted.

The two-day schedule to check before booking PDT in Homaesil

If you live near Homaesil and plan to get PDT, first check your schedule for the two days following the procedure. Since whether to proceed and how is decided through a doctor's examination and consultation, you can discuss the details below during that consultation as well.

• Whether you have any outdoor events or sports activities within two days after the procedure
• Whether your work involves a lot of sun exposure, such as sitting near a window, working outdoors, or driving
• Whether you're taking any medication that increases sensitivity to light
• Whether you've previously had a sun allergy or hives

If your job involves frequent outdoor activity, you can also schedule the procedure around a vacation or weekend. Whether you can stay indoors for two days is the first thing to consider when choosing a date.

FAQ

Q. Do I need to avoid light even on cloudy days?

A. Yes, UV rays and visible light still pass through even when it's cloudy. For 48 hours, please cover your face whenever you go outside, regardless of the weather.

Q. Can I shower or bathe on the day I receive PDT?

A. A quick shower with lukewarm water is often fine, but please avoid hot baths and saunas for a few days. Heat can prolong redness and stinging.

Q. Can I look at my phone or computer screen?

A. Looking at a screen itself is usually fine, but lower the brightness and avoid holding it close to your face for long periods. If you're concerned, feel free to ask about your living space and work environment during the post-procedure guidance.

Q. When can I start exercising?

A. Sweating a lot can prolong redness and stinging, so it's better to limit yourself to light walking for a few days. For outdoor exercise, keep using sun protection even after the 48 hours have passed.

Q. Can I go back to my normal routine once 48 hours have passed?

A. Even after the light-avoidance period ends, your skin may remain sensitive for a while. Keep applying sunscreen consistently, and hold off on exfoliants or harsh cosmetics until your skin has calmed down.
