What is DSAP?
Disseminated Superficial Actinic Porokeratosis (DSAP) is a common skin condition in Australia, often appearing as small, round, brownish-red spots on the arms, legs, and other sun-exposed areas.
While these spots might look like simple sunspots, they have a unique feature: a slightly raised, scaly border known as a cornoid lamella.
The “Bricks and Mortar” Explanation
To understand DSAP, imagine your skin is a brick wall. In healthy skin, the “bricks” (skin cells) are laid flat and held together by a strong “mortar” made of natural fats and oils, including cholesterol.
In areas affected by DSAP, there is a localised “glitch” in the skin’s ability to produce this mortar. Because the skin is lipid-starved, the bricks don’t lay flat; instead, they clump together and pile up at the edges of the spot. This process is primarily triggered and worsened by years of exposure to Australian UV radiation.
The Role of a Compounding Pharmacy
- Customised Strengths:Â We can create topical treatments in the exact concentrations recommended by recent clinical research, which may not be available commercially.
- Targeting the Cause:Â New research suggests that certain ingredients can help “bypass” the genetic metabolic block in DSAP skin cells, helping them mature more normally.
- Allergen-Free Bases:Â Many commercial creams contain preservatives or fragrances that can irritate sensitive DSAP skin. We can formulate your treatment in hypoallergenic or “clean” bases.
- Combination Therapy:Â We can combine multiple active ingredients into a single application to improve compliance and effectiveness.
How to Use Compounded Topical Treatments
- Cleanse:Â Use a gentle, fragrance-free cleanser and lukewarm water.
- Apply:Â Apply a thin layer of the compounded product directly to the affected lesions.
- Frequency:Â Most treatments are applied twice daily (morning and night).
- Consistency:Â It may take 4 to 12 weeks to see significant improvement.
- Storage:Â Keep your compounded product in a cool, dry place away from direct sunlight, as these formulations can be sensitive to heat.
Possible Side Effects
- Mild redness or “flushing” of the treated area.
- Occasional itching or stinging upon application.
- Dryness or slight peeling.
If you experience severe irritation, blistering, or an allergic reaction, stop use immediately and contact your doctor.
Managing DSAP with Dermaceutic
Because DSAP is linked to a weakened skin barrier and UV triggers, management focuses on replenishing lipids, normalising cell growth, and blocking UV rays. Dermaceutic offers high-performance, laboratory-grade formulas to support this process.
1. Rebuild the Lipid Barrier
Since your skin is struggling to produce its own “mortar,” you need to manually apply it.
-
Panthenol Ceutic: An ultra-nourishing restoration balm. It contains Panthenol and Shea Butter to soothe inflammation and provide the essential fatty acids needed to repair the skin barrier.
-
Hyal Ceutic: A high-concentration Hyaluronic Acid cream that intensely hydrates the skin, helping to soften and smooth the scaly texture of DSAP lesions.
2. Normalise Skin Cell Growth
To prevent cells from clumping at the edges of the spots, you can use ingredients that encourage more organised cell turnover.
-
Dermaceutic Activ Retinol (0.5 or 1.0): This Vitamin A serum helps “re-train” skin cells to mature and shed correctly. Over time, this can help flatten the raised borders of the lesions.
3. The Essential Shield
UV exposure is the primary driver of DSAP. Without daily protection, the condition will continue to progress.
-
K Ceutic: A specialised post-treatment cream with SPF 50 that contains Vitamin K to help calm the redness often seen in DSAP flare-ups.
Your Daily Maintenance Routine
| Time | Step | Recommended Product |
| Morning | Hydrate & Defend | Apply Hyal Ceutic followed by Sun Ceutic 50+. |
| Daytime | Protect | Re-apply Sun Ceutic or K Ceutic every 2 hours if outdoors. |
| Evening | Repair & Renew | Apply Activ Retinol (start 2 nights a week) followed by Panthenol Ceutic. |
