Actinic Keratosis Treatment in Melbourne (Ivanhoe + Diamond Creek)
Doctor-led treatment for sun damage and “precancer” — with laser-assisted photodynamic therapy (LA-PDT) as our most advanced in-clinic option.
Actinic keratoses (also called solar keratoses) are rough, sun-damaged patches that form on chronically exposed skin (face, scalp, ears, forearms, hands). They matter because a proportion can progress to squamous cell carcinoma over time, and because they’re a marker of “field damage” — meaning the surrounding skin has often accumulated significant UV injury. (1–3)
Our treatment philosophy is simple:
1.confirm the diagnosis,
2.match treatment to your AK pattern (single spot vs widespread field), and
3.prioritise long-term control and prevention, not just a quick “spot freeze”. (1–3)

Key takeaways
- LA-PDT is our most comprehensive in-clinic option for treating both visible AKs and the surrounding sun-damaged field — especially on the face and scalp. (1–3)
- Cryotherapy is an easy treatment for a small number of isolated lesions in non cosmetically sensitive areas (“single rough spots”). (1,2)
- Efudix (5-fluorouracil) and Aldara (imiquimod) are effective field treatments you apply at home — but they require commitment, good timing, and support through the reaction phase. (1–4)
- Sun protection and ongoing surveillance reduce recurrence and catch early skin cancers sooner. (1–3)
Why LA-PDT is our most prominent option
Laser-Assisted Photodynamic Therapy (LA-PDT)
LA-PDT combines two proven concepts: photodynamic therapy (PDT) (a photosensitising cream plus a controlled light source) and laser assistance to enhance treatment penetration and field coverage. PDT is a recognised treatment option in major guidelines; many clinicians use it particularly where cosmetic outcomes matter (face/scalp). (1–3)
Why patients choose LA-PDT (especially for face/scalp):
- Treats the field, not just the visible spots (important when there are multiple AKs or widespread sun damage). (1–3)
- Doctor-led and clinic-controlled: no “did I apply it right?” uncertainty.
- Often excellent cosmetic outcomes compared with repeated freezing in cosmetically sensitive areas. (3)
- Efficient: treatment is delivered in a structured session with clear aftercare.
Best suited for:
- Multiple AKs in one region (“field cancerisation”) — particularly face and scalp (including bald scalp) (1–3)
- Patients who want an in-clinic, technology-assisted approach rather than weeks of topical reaction
- Recurrent AKs despite ongoing spot treatment
What to expect (high level):
- assessment + photos if needed
- laser preparation (to improve uptake)
- application of photosensitiser + incubation
- controlled light activation
- a predictable recovery phase (redness, dryness, crusting/flaking depending on protocol and your skin)

Other evidence-based treatment options we offer
1) Cryotherapy (freezing) — OK for single-multiple lesions where cosmesis isn’t a concern
Cryotherapy is a lesion-directed treatment: quick, effective for isolated AKs, and commonly performed at the time of assessment. (1,2)
Pros
- fast, in-clinic
- ideal for a small number of discrete lesions (1,2)
Cons
- doesn’t treat the surrounding field damage
- When done properly – can cause blistering, pigment change, and can cause small white scars where the precancer used to be (especially on thinner skin) (2) – this is mainly why I never use cryotherapy on the face or anywhere that patients don’t want scars
2) Efudix (5-fluorouracil) — field treatment at home
Efudix is one of the most effective field therapies for AKs and is strongly recommended in clinical guidelines. (1,4) It works by selectively targeting rapidly dividing abnormal sun-damaged cells, which creates a predictable inflammatory reaction before healing. (1,4). The area that is treated becomes very red and painful, and often oozes yellow or green exudate (even when not infected).
Best suited for:
- widespread AKs on face/scalp/forearms
- patients who can commit to the full course (4 weeks) and recovery window (1,4)
Cons
- Quite difficult to tolerate on large areas for the 4 week course

3) Aldara (imiquimod) — immune-based field treatment at home
Aldara stimulates local immune activity to clear AKs and is also strongly recommended in guidelines. (1,3) It can be particularly useful when an immune-driven approach suits the pattern and location.
Best suited for:
- field treatment (multiple AKs in one area)
- patients who prefer an immune-modulating option and can manage the reaction phase (1,3)

Cons
- Quite difficult to tolerate on large areas – often the total course is 8 weeks
How we choose the right option for you
During your consultation, we match treatment to:
- How many lesions you have (single spot vs multiple) (1–3)
- Where they are (face/scalp vs limbs — cosmetic priorities and healing differ) (1–3)
- Thickness (hyperkeratotic lesions may need debulking/targeted treatment first) (2)
- Your timeline (downtime tolerance matters)
- Your risk profile (immunosuppression, prior skin cancers, rapid recurrence) (2,3)

Prevention and long-term control (this is where outcomes are won)
Even after successful treatment, AKs often recur because the underlying UV damage remains. Evidence-based prevention includes:
- consistent UV protection (daily broad-spectrum sunscreen, hats, shade) (1–3)
- ongoing skin checks where appropriate
- treating “field change” proactively rather than chasing individual spots forever (1–3)

Frequently asked questions
Are actinic keratoses skin cancer?
They’re precancerous sun-damage lesions. Technically the difference between actinic keratosis and early squamous cell cancer is only that in SCCis the cells are all throughout the epidermal thickness (ie the same cells that are called “precancer” are then called “cancer” once they are through the full thickness of the epidermis). Some can progress to squamous cell carcinoma, and they signal a higher-risk sun-damaged field. (2,3)
Is LA-PDT better than creams?
It depends on your pattern and goals. Guidelines strongly support 5-fluorouracil and imiquimod, and LA-PDT is also recommended (often conditionally) with strong cosmetic performance in many settings. (1,3) LA-PDT is most valuable when you want a clinic-controlled, field-directed, technology-assisted treatment pathway.
Will they come back?
They can. That’s why prevention, surveillance, and field-based strategies matter. (1–3)
