This springs discussions around dietary supplements to protect the skin have brought Polypodium leucotomos extract (PLE) into the spotlight. This compound has been isolated from a fern species that grows abundantly in Central and South America. It has hit the limelight as a potential source of strong antioxidant and anti-inflammatory effects. Researchers are investigating PLE both for its sun protective properties. They recommend against relying on it as a panacea for UV protection.
PLE also has very special qualities that allow it to neutralize free radical damage done by UV exposure. This novel mechanism holds promise for protecting skin from sun damage. It is different from your regular topical sunscreens, which primarily act like a physical barrier to UV rays. Dermatologists warn a common use of PLE as a sun protection ingredient still has unknown effectiveness.
Understanding Polypodium Leucotomos Extract
The Polypodium leucotomos extract has been shown to be protective against oxidative stress in the skin. In this way, by reducing the range of harmful effects produced by free radicals, PLE can play a role in creating a healthier skin environment. Its antioxidant and anti-inflammatory functions have been widely established. This makes it by far the most studied ingredient in any dietary supplement aimed at protecting against sun damage.
Even with these promising advantages, PLE is still considered a dietary supplement. The Food and Drug Administration (FDA) does not exert regulatory authority over PLE. This absence of regulation leads to questions about the purity, concentration, and safety of products featuring this extract. Consumers are left guessing to know whether or not these products really contain what they claim. Additionally, they have some fear about the safety of using these items.
“More studies need to be done on these products in order to make any real claims regarding sun protection,” – Hale
Precautions Pregnant or breastfeeding women should not take PLE supplementation. Furthermore, those with allergies to ferns would not be appropriate subjects either.
Limitations of PLE as Sun Protection
Though PLE has great potential, experts are cautioning not to depend on it alone for UV protection. Dermatologists further emphasize that PLE does not offer adequate protection from UV rays on its own. Rather, they suggest incorporating PLE as part of a multifaceted sun protection approach that utilizes traditional topical sunscreens.
“These pills should be used in conjunction with traditional, topical sunscreens,” – Nazarian
This two-fold method works to provide optimum protection—even in the sun! Most importantly, it acknowledges that oral supplements will not have the same effectiveness of topical products. There is an agreement in the dermatological community that additional studies beyond the laboratory stage will be required to explore just how far PLE can protect as well.
Considerations Before Using PLE
Before starting any supplement regimen, people need to think about their specific health needs. Patients on immunomodulatory agents, or other targeted therapies such as PLE can be PLE contraindicated. Dermatologists remind consumers to speak to their healthcare provider before introducing these kinds of supplements into their routine.
Additionally, although PLE has been found to be well tolerated for most users, personal intolerance from use may occur. Thus, prospective users should stay attuned to their medical background and any potential contraindications with PLE intake.
“We don’t really have definitive answers as to how much sun protection is really provided with oral photoprotection,” – Hale
