What Are Oral Sunscreens and How Do They Work?

With growing concern about skin health and protection, many individuals are turning to novel ways to protect their skin from the detrimental effects of ultraviolet (UV) radiation. Oral sunscreen is one such innovative product that is gaining popularity. But what are oral sunscreens and how do they work? Let's discuss the details, using insights from academic research and specific products like Heliocare Oral Sunblock and Fernblock®.

Understanding Oral Sunscreens

Oral sunscreens are dietary supplements that protect the skin from UV rays from the inside out. Unlike traditional topical sunscreens, which form a physical barrier on the skin's surface, oral sunscreens operate by enhancing the skin's natural UV protection processes. These supplements usually contain a combination of natural antioxidants, vitamins, and other chemicals renowned for their photoprotective benefits.

Key Ingredients and Their Benefits

1. Fernblock® Fernblock®, derived from the fern Polypodium leucotomos, is a primary ingredient in many oral sunscreens, including Heliocare. Research published in the National Library of Medicine has highlighted Fernblock's potent antioxidant properties, which help neutralize free radicals generated by UV exposure. Additionally, Fernblock® has been shown to reduce UV-induced DNA damage, inhibit the formation of sunburn cells, and enhance skin resilience to UV radiation​ (Heliocare)​​ (Cantabria Labs)​.
2. Antioxidants Oral sunscreens often contain antioxidants like vitamins C and E, lycopene, and lutein. These antioxidants work synergistically to protect skin cells from oxidative stress caused by UV exposure. They help in reducing inflammation, promoting skin healing, and preventing long-term damage such as premature aging and skin cancer .

Mechanisms of Action

The effectiveness of oral sunscreens lies in their multifaceted approach to skin protection:

1. Neutralizing Free Radicals UV radiation can cause the formation of free radicals, unstable molecules that damage cells and DNA. The antioxidants in oral sunscreens neutralize these free radicals, reducing oxidative stress and preventing cellular damage .
2. Enhancing DNA Repair Some ingredients in oral sunscreens, such as Fernblock®, support the body's natural DNA repair mechanisms. This helps in correcting UV-induced DNA damage more efficiently, reducing the risk of mutations that can lead to skin cancer​ (Heliocare)​.
3. Anti-Inflammatory Effects Oral sunscreens also exhibit anti-inflammatory properties. They help in mitigating the inflammatory response triggered by UV exposure, which is crucial in preventing skin redness, swelling, and long-term photodamage .

Clinical Evidence

Clinical studies have shown promising results for oral sunscreens like Heliocare. For instance, a study published in the National Library of Medicine demonstrated that participants taking Heliocare Oral exhibited significantly reduced UV-induced skin damage compared to those who did not take the supplement. The study highlighted improvements in skin elasticity, reduced wrinkle formation, and enhanced overall skin health​ (Heliocare)​.

Another clinical trial focused on the protective effects of Fernblock® against UV radiation. It found that Fernblock® supplementation significantly decreased the formation of cyclobutane pyrimidine dimers (CPDs) and 8-hydroxy-2'-deoxyguanosine (8-OH-dG) – markers of DNA damage and oxidative stress, respectively. This underscores Fernblock's role in protecting against both immediate and long-term UV damage .

Usage and Recommendations

While oral sunscreens offer a convenient and effective way to enhance photoprotection, they should not be considered a replacement for topical sunscreens. Instead, they work best as a complementary measure. It's recommended to use oral sunscreens in conjunction with topical sunscreens, wearing protective clothing, and avoiding excessive sun exposure, especially during peak hours.

Conclusion

Oral sunscreens represent a promising advancement in skin protection, harnessing the power of natural antioxidants and other photoprotective compounds to bolster the skin's defenses against UV radiation. Products like Heliocare Oral Sunblock, enriched with Fernblock®, have shown significant clinical benefits, making them a valuable addition to comprehensive sun protection regimens. As always, consult with a healthcare professional before starting any new supplement to ensure it aligns with your individual health needs.
