Introducing ASPA-Fernblock®: The next generation of sunscreen innovation

When it comes to protecting your skin from the sun, choosing the right sunscreen for your face is about more than just SPF. The best sun protection should shield against UV rays, infrared radiation, and visible light while also supporting skin health at a deeper level.

Now, HELIOCARE from Cantabria Labs is raising the bar in sun protection with ASPA-Fernblock®, a game-changing, bioactive skin technology that goes beyond traditional sunscreen ingredients to optimise vitamin D function in the skin.

Why vitamin D matters for your skin

Vitamin D plays a crucial role in cell renewal, repair, and immune defence¹. It helps regulate skin cell turnover, supports the skin barrier, and plays an essential part in collagen synthesis and wound healing.

While the sun helps the skin produce vitamin D, excessive UV exposure can actually damage vitamin D receptors (VDRs), making it harder for the skin to synthesise and use this vital nutrient.

• UV overexposure breaks down vitamin D instead of increasing its stores¹
• Oxidative stress damages vitamin D receptors, reducing uptake and effectiveness²
• DNA damage caused by UV rays prioritises skin cell survival, which can interfere with vitamin D activation³

This presents a dilemma: How can we protect our skin from UV-induced damage without compromising its ability to benefit from vitamin D?

The answer lies in ASPA-Fernblock®, and the revolutionary OptiD Effect.

What makes ASPA-Fernblock® different?

A breakthrough in skincare science

For years, HELIOCARE has led the way in photoprotection with Fernblock® technology - a powerful antioxidant extract from the Polypodium leucotomos fern with clinically proven DNA repair and anti-ageing benefits.

Now, ASPA-Fernblock® takes these benefits even further with the OptiD Effect, a scientifically backed innovation designed to preserve and optimise vitamin D function in the skin.

How the OptiD Effect works:

• Preserves vitamin D receptors (VDRs) – Oxidative stress from UV exposure can damage these receptors, making it harder for the skin to utilise vitamin D effectively. ASPA-Fernblock® protects VDRs, allowing skin to maintain optimal vitamin D activity²
• Enhances DNA repair – UV radiation damages skin cells and accelerates ageing. ASPA-Fernblock® supports DNA repair mechanisms, ensuring the skin remains resilient⁴
• Boosts antioxidant protection – ASPA-Fernblock® contains Aspalathus linearis (Rooibos) extract, a powerful antioxidant that neutralises free radicals, reducing oxidative stress and inflammation²

A sunscreen that works for your skin’s health

Unlike conventional sunscreens, which focus only on blocking UV rays, HELIOCARE 360° with ASPA-Fernblock® takes a holistic approach:

High-level sun protection

• Broad-spectrum defence against UVB, UVA, infrared, and visible light, ensuring complete sun protection
• Prevents premature ageing, sunspots, and collagen breakdown⁵

Advanced antioxidant defence

• Fernblock® and Rooibos extract neutralise free radicals, reducing inflammation and DNA damage³
• Helps prevent skin pigmentation, fine lines, and sun-induced damage

Supports vitamin D function

• Unlike traditional sunscreens, ASPA-Fernblock® allows the skin to maintain vitamin D activity while staying protected²
• Helps maintain skin vitality, hydration, and long-term health

The science behind ASPA-Fernblock®

As with all Cantabria Labs products and technologies, the effectiveness of ASPA-Fernblock® is backed by clinical research. A 2025 study presented at CILAD (Congreso Ibero Latinoamericano de Dermatología) found that ASPA-Fernblock® preserves vitamin D receptor expression even when skin is exposed to oxidative stress².

Extensive clinical studies also show that Fernblock® reduces DNA damage and prevents sun-induced collagen breakdown, reinforcing skin strength and elasticity⁶.

Combined with Rooibos extract, ASPA-Fernblock® provides an extra layer of protection against photoageing and UV damage.
