Photodynamic Therapy Aftercare
At DRS Skincare Hamilton, ON

Aftercare starts before your PDT session. Proper preparation ensures your skin recovers efficiently afterward.

Before treatment, have these essentials ready at home:

• Ice packs or cold compresses
• A gentle, fragrance-free cleanser
• Non-irritating moisturizer (no active ingredients)

Following your dermatologist’s instructions and avoiding sun exposure before your appointment can also reduce downtime and improve recovery.

After your photodynamic therapy session, it’s normal to experience temporary redness, swelling, or mild peeling. Your skin may feel tight, itchy, or slightly warm—similar to a sunburn.

Typical reactions include:

• Redness and swelling
• Peeling or flaking
• Rough or dry texture
• Itching or mild burning sensation

These effects mean the treatment is actively stimulating renewal. Healing times vary depending on whether PDT was performed for actinic keratoses or acne, but photosensitivity is always expected. Because PDT involves a photosensitizing medication, your skin becomes highly reactive to sunlight and bright indoor lighting. Protecting your skin from light exposure during the first 48 hours is essential for safe healing.

Your skin will be extremely light-sensitive immediately after treatment. To avoid complications:

• Stay indoors for at least 48 hours.
• Keep away from direct sunlight—even through windows.
• Avoid bright indoor lights (especially fluorescent bulbs).
• Once cleared by your dermatologist, resume broad-spectrum SPF 30+ sunscreen use.
• Wear wide-brimmed hats, UPF clothing, and sunglasses when outdoors.

These precautions help prevent burns, hyperpigmentation, and further sun damage.

After photodynamic therapy, your skin barrier needs time to repair. Keep your routine simple:

1. Cleanse gently with a mild, non-foaming cleanser.
2. Moisturize frequently to reduce dryness and promote healing.
3. Soothe irritation with cool compresses or ice packs.
4. Avoid makeup, shaving, or exfoliating until the skin has healed.
5. Skip active ingredients such as:
   • Retinol and retinoids
   • Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs)
   • Vitamin C
   • Benzoyl peroxide

Your dermatologist at DRS Skincare will tell you when it’s safe to resume your regular skincare products.

• PDT for actinic keratoses and sun damage: Skin typically improves within 7–14 days, appearing clearer, smoother, and more even in tone.
• PDT for acne: Breakouts may temporarily worsen before improvement.

Over several weeks, patients often notice:

• Fewer pimples and blackheads
• Less oil production
• Refined texture and tone

Most patients see the best results with a series of 2–3 PDT sessions, spaced 4–6 weeks apart, as recommended by our dermatologist.
