Critical Wavelength Protection.
Dermatologist-recommended SPF 50 Continuous Spray and Max-Sport® SPF 30. Non-greasy broad spectrum protection for 18 holes under the African sun.
Sun Care Formulated For Golfers & Sports Professionals.
LUCA® was developed by Surgical Pathologist Dr. Karl Gruber for his children, Elisa and Luca, who suffered skin irritation from conventional sunscreens. Even after trying numerous commercial products and multiple visits to dermatologists, they were unable to find a non-irritating product that delivered reliable high-level protection.
In his surgical pathology practice, Dr. Gruber witnessed an alarming rise in skin cancers, including melanoma. Recognizing that standard sunscreens often focus only on UVB rays while failing to protect against long-wave UVA rays, he created LUCA® to educate consumers on "Critical Wavelength®" protection and provide wearable, comfortable sun care.

UVA / UVB Protection & Critical Wavelength® Explained
Why SPF numbers alone don't tell the full story, and why Critical Wavelength® is the true gold standard for skin protection.
Why Standard SPF Isn't Enough
Most commercial sunscreens highlight only their SPF rating. However, SPF only measures protection against UVB rays, which account for only 5% of solar UV radiation.
- 95% of solar radiation is UVA: UVA rays penetrate deeper into the dermis, causing oxidative collagen breakdown, fine lines, wrinkles, sunspots, and melanoma.
- Constant Intensity: Unlike UVB rays which peak at midday in summer, UVA intensity remains constant all day and all year long.
- No Warning Signs: UVA rays do not cause sunburn redness, meaning skin damage accumulates silently without immediate pain.
What is Critical Wavelength®?
Critical Wavelength® measures how far out across the UV spectrum a sunscreen protection umbrella extends starting from 290nm.
- FDA Broad Spectrum Requirement: The US FDA specifies a minimum Critical Wavelength over 370nm to qualify as broad spectrum.
- LUCA® Exceeds Standards: LUCA Continuous Spray reaches certified 376nm Critical Wavelength®, delivering superior long-wave UVA coverage.
- Transparent Labeling: LUCA® was the first brand to prominently print the Critical Wavelength value directly on every bottle label.
