Do Oral Sunscreen Supplements Work? Recent studies have explored the efficacy of oral supplements as a form of “oral sunscreen”. But do these supplements actually provide any real benefits for sun protection? Let’s dive into what these supplements are, how they work, and if they should be part of your sun protection regimen.
What Are Oral Sunscreen Supplements?
One example of an oral sunscreen product on the market is Heliocare®, which contains Polypodium leucotomos extract (PLE). This is a fern extract, combined with other antioxidants like green tea extract and beta-carotene. These antioxidants are known for their ability to protect skin cells from damage. It does this by neutralizing free radicals—molecules that can damage your skin’s DNA and contribute to skin cancer and premature aging.
PLE has been used for decades to treat various skin conditions such as psoriasis, dermatitis, and vitiligo. Research suggests that PLE may have benefits in preserving the structure of the skin by acting as an antioxidant. There are no long-term negative effects associated with taking PLE as a dietary supplement, but the potential interactions between PLE and other medications, such as heart medications, have not been fully explored.
Do Oral Sunscreens Actually Work?
The short answer is no. Oral sunscreen supplements cannot replace topical sunscreen. While antioxidants in these supplements can help protect skin cells, they do not prevent the damage caused by UV rays. Studies have not shown that oral sunscreen will protect you from sunburn or skin damage caused by UV exposure.
The Limitations of Oral Sunscreens
Oral supplements like Heliocare® can help reduce oxidative stress on skin cells but do not offer sufficient protection against the harmful effects of UV radiation. Sun avoidance and topical sunscreen are still the most effective ways to prevent skin cancer and sun-damaged skin.
Best Sun Protection Practices
Regardless of your skin type, history of sun exposure, or skin cancer history, it’s essential to practice traditional sun protection measures:
-
Wear wide-brimmed hats to protect your face and neck.
-
Stay under large umbrellas when possible.
-
Apply sunscreen with at least SPF 60 daily to all exposed areas of the skin.
While oral sunscreen supplements may offer some benefits, they are not a substitute for physical sun protection and should be used as a supplement, not a replacement for topical sunscreens.
