>50%
lower rate of new nonmelanoma skin cancers
Observed when supplementation began after a first skin cancer.
20%fewer precancerous lesions at 9 months
JAMA observational cohort; matched comparison.
JAMA observed a 54% lower hazard when nicotinamide began after the first skin cancer. In a separate NEJM trial, actinic keratosis counts were 20% lower at 9 months versus placebo.

80%
of participants showed improved UV response
Measured by colorimetry after a PLE-containing supplement.
Colorimetric response after five days of supplementation.
A PLE-containing supplement improved measured UV response in 80% of participants. A separate 8-week trial of PLE, red orange and vitamins found greater UV tolerance and reduced erythema after exposure.

A clinical study on Sun Powder and skin erythemaA clinical study on
Sun Powder and skin erythema
Preliminary Results
80%erythema
reduction
In a significant portion of participants, post-ingestion redness was visibly reduced compared to the baseline data.
Method
Controlled broad-spectrum laser calibrated to simulate 6 hours of peak midday sun (UVA + UVB).
One hour post-exposure, measured erythema (redness).
Participants then consumed one dose of Sun Powder and were exposed again to the laser.
One hour post-ingestion, measured erythema again.
Why measure redness?
Redness is the earliest, most visible sign of UV damage — a proxy for DNA damage, inflammation, and sunburn. Reducing it post-exposure signals faster recovery and protection.
Baseline
1 hour post-exposure to UVA + UVB
With Sun Powder
1 hour post-ingestion & more UVA + UVB exposure
What these results suggest
- Potential anti-inflammatory effects can occur within just 1 hour — even after UV damage has begun.
- This could indicate Sun Powder’s ingredients act fast to mitigate visible sun damage, rather than just offering long-term support.
Your skin is a living system. Sun Powder supports it
Cellular maintenance
Nutrients help sustain normal cellular functions, including energy production and repair.
Antioxidant support
Antioxidants play a role in the body’s response to everyday oxidative stress.
Structure + moisture
Collagen and hyaluronic acid are part of skin’s supporting matrix.
A little more clarity.
Does this replace sunscreen?
No. Keep using sunscreen, protective clothing and shade. Sun Powder is a daily supplement alongside those habits.
Why publish a small preliminary study?
Exploratory work can guide larger studies. It is an early signal to investigate, with clear limits on what we can conclude.
Good science.
