Fernblock ®

Polypodium leucotomos

IFC Group I+D Fernblock

Fernblock ® is the base active ingredient of our sun protection cosmetic line, Heliocare ®.

It contains Polypodium leucotomos fern extract, the efficacy of which has been proven in numerous scientific journals. Fernblock Technology ® is the only technology in the world that ensures complete photoprotection. Developed by Cantabria Labs in collaboration with Harvard Medical School, it boasts a unique protection mechanism against the sun both short and long-term. Beyond mere protection against sunburn, Fernblock offers us four levels of protection that helps prevent photoaging and skin cancer.


Natural protection

The power of Fernblock ® comes from Polypodium leucotomos, a tropical fern originating from Central America that during its transition from aquatic to terrestrial life developed self-defence and repair mechanisms against the sun. The Chorotegas tribe of Honduras was the first to discover its excellent skincare properties.

Short and long-term production

There are different types of sun radiation that affect our skin causing significant damage. Most creams protect us from UVB rays but not UVA rays which are responsible for the long-term negatives effects deep in the skin’s epidermis.

Fernblock ®, together with an advanced combination of physical and chemical filters, protects the skin from both types of radiation (UVA /UVB) and prevent immediate damage (burns) and that which occurs over the passage of time: aging, liver spots, loss of defences, allergies and even skin cancer.

Four levels of protection

Against erythema: Fernblock ® boosts the resistance of skin and mucous membranes against the sun and reinforces its protection capacity against sunburn caused by UVB rays.

Antioxidant and antiaging: The advanced combination of Fernblock filters combats free radicals so that they do not alter the architecture of the skin, thus preventing the appearance of wrinkles, dryness and pigmentation.

Protection and DNA repair: Sun radiation can alter our genetic material and cause the appearance of serious diseases such as skin cancer. Fernblock ® reduces that damage and helps our body repair the effects caused by UVB.

Immunological protection: The sun weakens our skin’s defence system. Fernblock ®, taken orally, protects and regulates the skin’s defences so that they remain intact to combat against external aggressions.

Furthermore, our state-of-the-art Fernblock ®, Fernblock + ®, contained in Heliocare 360º ®, has shown higher activity and photo immunoprotective efficacy against UVB, UVA, Visible and infrared, protecting us from the entire solar spectrum.
