DSAP Skin Condition: What My Diagnosis Taught Me About Skin, Hormones and UV Exposure
I was recently diagnosed with DSAP, which stands for disseminated superficial actinic porokeratosis.
DSAP is a genetic skin condition linked with UV exposure. It usually shows up as small, dry, rough patches or ring-like lesions, often on sun-exposed areas such as the arms and legs.
For me, the diagnosis makes sense.
I grew up in New Zealand, running around outside on a farm, in the sun, completely unaware that my skin was storing that history. New Zealand’s thinner ozone layer and high UV environment certainly didn’t help.
But I can understand it clinically and still feel upset by it personally.
As a woman, it is hard to be told you have a visible skin condition that is not curable and not especially pretty.
What is DSAP?
DSAP is not contagious. It is not a skincare failure. And it is not something a serum is going to fix.
It is considered a disorder of keratinisation, which means it affects the way skin cells grow and shed. It is often associated with genetic susceptibility and years of UV exposure.
That distinction matters.
DSAP is not just “sun damage”. It is usually genetic susceptibility plus environmental exposure over time.
The predisposition is genetic. The exposure is what helps bring it to the surface.
Why mine became obvious in my mid 40s
What I find interesting is that my DSAP became more obvious in my mid 40s, as my oestrogen was declining.
To be clear, oestrogen did not cause my DSAP.
But oestrogen has a significant role in skin health. As oestrogen falls in perimenopause and menopause, skin can become drier, thinner, less elastic and less resilient. For some women, this is when changes that have been building quietly for years start to show more clearly.
That is exactly why I never look at skin as just surface.
Skin is not separate from the rest of the body. It reflects hormones, gut function, inflammation, immune activity, blood sugar, nutrient status, genetics, environment and time.
Why skin is rarely just one thing
In clinic, I see this pattern constantly.
A woman comes in with skin changes and has usually been told to change her skincare, use a stronger active, or try another topical.
Sometimes that is needed.
But often, the skin is responding to something deeper.
It may be hormone shifts. It may be gut inflammation. It may be blood sugar instability, nutrient insufficiency, immune activation, stress physiology, or accumulated UV exposure.
With DSAP, dermatology matters. Proper diagnosis matters. Sun protection matters. Regular skin checks matter.
But from a functional medicine perspective, I also want to understand the terrain underneath the skin.
How DSAP is managed
Sadly, there is no cure for DSAP, so for me this now means long-term management.
That includes proper sun protection, regular skin checks, and a compounded statin and cholesterol cream.
Not glamorous. Very real.
There is emerging evidence for topical statin treatment, including lovastatin with or without cholesterol, but this is something to discuss with a dermatologist or prescribing clinician. DSAP needs proper medical diagnosis and monitoring, especially because lesions can resemble other skin conditions.
Why I test, not guess
This diagnosis has been another reminder of why I work the way I do.
Skin holds history.
Genetics, hormones, gut function, immune activity, inflammation, blood sugar, environment and UV exposure all leave their mark over time.
That is why I test, not guess.
Because when we understand what the skin is responding to, we can support it properly.
Sometimes skin needs topical treatment. Sometimes it needs internal support. Often, it needs both.
