How Effective Are Oral Sunblocks Compared to Traditional Topical Sunscreens?

As awareness of the harmful effects of UV radiation continues to grow, more individuals are exploring different methods to protect their skin. While traditional topical sunscreens have long been the go-to for sun protection, oral sunblocks have emerged as an innovative alternative. This blog delves into the effectiveness of oral sunblocks compared to traditional topical sunscreens, with insights from academic articles and specific mentions of products like Heliocare and Fernblock®.

Understanding Oral Sunblocks

Oral sunblocks are dietary supplements that aim to protect the skin from UV damage from the inside out. These supplements often contain antioxidants and natural extracts known for their photoprotective properties. One of the most popular ingredients in oral sunblocks is Fernblock®, derived from the fern Polypodium leucotomos. Heliocare is a well-known brand that incorporates Fernblock® in its oral sunblock products.

Mechanisms of Action

1. Antioxidant Protection Oral sunblocks work by enhancing the body's natural defense mechanisms. Ingredients like Fernblock® provide powerful antioxidant protection, neutralizing free radicals generated by UV exposure. This helps to reduce oxidative stress and prevent cellular damage.
2. DNA Repair Studies have shown that oral sunblocks can support the skin's DNA repair processes. Fernblock®, for instance, has been demonstrated to reduce UV-induced DNA damage by inhibiting the formation of cyclobutane pyrimidine dimers (CPDs) and reducing oxidative stress markers like 8-hydroxy-2'-deoxyguanosine (8-OH-dG)​ (Heliocare)​​ (Cantabria Labs)​.
3. Anti-Inflammatory Effects Oral sunblocks also exhibit anti-inflammatory properties, which help in mitigating the inflammatory response caused by UV radiation. This is crucial for preventing long-term skin damage and maintaining skin health.

Clinical Evidence Supporting Oral Sunblocks

Several clinical studies have highlighted the effectiveness of oral sunblocks. A study published in the National Library of Medicine evaluated the protective effects of Heliocare Oral and found significant reductions in UV-induced skin damage among participants who took the supplement. The study noted improvements in skin elasticity, reduced wrinkle formation, and enhanced overall skin health​ (Heliocare)​.

Another study focused on Fernblock® demonstrated its ability to decrease the formation of UV-induced DNA damage markers and improve the skin's resistance to UV radiation. This research underscores the potential of oral sunblocks to provide comprehensive protection against UV damage​ (Heliocare)​.

Comparison with Traditional Topical Sunscreens

1. Mode of Application Traditional topical sunscreens create a physical barrier on the skin's surface, reflecting or absorbing UV radiation to prevent it from penetrating the skin. Oral sunblocks, on the other hand, work from within the body to bolster the skin's natural defenses.
2. Coverage and Convenience One of the significant advantages of oral sunblocks is their ability to provide uniform protection across all areas of the skin, including hard-to-reach spots. They are also convenient to use, eliminating the need for frequent reapplication required by topical sunscreens.
3. Combined Use Experts suggest that oral sunblocks should not replace traditional sunscreens but rather complement them. Combining both methods can provide enhanced protection, leveraging the external barrier provided by topical sunscreens and the internal defense mechanisms boosted by oral sunblocks.

Conclusion

Oral sunblocks, with key ingredients like Fernblock® and products such as Heliocare, offer a promising approach to sun protection. They provide antioxidant, anti-inflammatory, and DNA repair benefits that can significantly enhance skin health and resilience to UV damage. However, they are most effective when used in conjunction with traditional topical sunscreens, ensuring comprehensive protection against the harmful effects of UV radiation.

As always, it is advisable to consult with a healthcare professional before starting any new supplement regimen, especially for individuals with specific health conditions or concerns. With the right combination of oral and topical sun protection, you can enjoy the sun safely and maintain healthier, more resilient skin.
