Every Heliocare product contains Fernblock®, a supercharged fern derived anti-oxidant that supports a health response to free radicals in the skin. Scientifically studied for over 20 years, Fernblock® & Fernblock+® are the main active ingredient in every Heliocare product.

How Fernblock® helps your skin

Fernblock® helps protect the skin from the harmful effects of solar radiation in the following ways:

  • DNA - Fernblock® helps support the body's natural DNA repair system
  • Antioxidant - Fernblock® provides skin targeted antioxidant support for cutaneous cellular health
  • Immune system - Fernblock® supports healthy skin immunity
  • Targeted for Skin - Fernblock® has been scientifically shown to effectively support the health of the body's largest organ - your skin

Today, Fernblock® is the only standardized Polypodium leucotomos extract on the market.

Origin and Development

Fernblock® technology arose from research by the Cantabria Labs Group together with the research team of Dr. Fitzpatrick of Harvard University (Harvard Medical School) with the aim of developing a complete sun protection mechanism. 

Dr fitzpatrick, Dr Patal and Dr Gonzalez of Harvard Medical School 1997

They demonstrated that this extract not only prevents immediate damage such as sunburn, but also provides protection capable of preventing long-term negative effects such as DNA damage, skin aging, loss of defenses or sun allergies.

Our extraction method is what guarantees maximum efficacy and safety: It is obtained from selected plants that grow under controlled conditions in laboratory processes according to Pharmaceutical Quality Standard.

Fernblock® protection levels

Fernblock® has shown numerous benefits, both topically and orally, in more than 50 studies and scientific publications. The effectiveness of this technology continues to be investigated with excellent results. In addition, its extraction method has been optimized, enhancing its activity and resulting in a new generation extract: Fernblock®+.

Sun protection

Fernblock® has been shown to multiply the skin’s resistance to sunburn. Its protective activity extends to the entire radiation spectrum protecting our skin from the specific damage caused by the 4 types of radiation (UVB, UVA, Visible and IR).

Repairing DNA damage

Solar radiation causes damage to our cell DNA, which builds up and can lead to health problems. Fernblock® technology has been shown to prevent the formation of this damage and increase and accelerate its repair. This activity helps prevent sun damage from accumulating, achieving advanced photoprotection levels.

Antioxidant activity

The powerful antioxidant action of Fernblock® is due to different molecules concentrated in the extract, able to neutralize and eliminate the free radicals generated during and after exposure.

Prevention of photoaging and pigmentation control

Fernblock® technology protects our skin cells and increases collagen, hyaluronic acid and elastin, fundamental components to maintain its structure. This prevents wrinkle formation and loss of firmness. It also helps reduce the intensity and size of sun spots and improves skin resistance to pigmentation.

Immune defense

Our skin has an important defense system against external aggressions that is negatively affected by the sun. Increased sun exposure increases our vulnerability. Fernblock® protects and regulates skin defenses so that they remain intact against external threats.


Fernblock® enhances HELIOCARE Sunscreen Activity (1)

New clinical data shows that HELIOCARE topical sunscreen (sun filters + Fernblock®) offers significant advantages with respect to sunscreen containing only sun filters. While sun filters alone can provide benefits beyond simply increasing MED, the addition of Fernblock® to topical sunscreen can significantly increase the photoimmunoprotection activity of the formulation, further reducing erythema, MMP-1 and pigmentation and protecting DNA and Langerhans cells. HELIOCARE sunscreens, with HELIOCARE’s exclusive Fernblock® Technology, go beyond traditional sun filter protection by providing advanced Dermatological Sun protection for the prevention of photoaging and skin cancer.
