As the methods of safeguarding against the sun’s harmful rays evolve, a new contender has emerged in the form of sunscreen capsules.
Unlike traditional sunscreen creams, which function by either absorbing or reflecting harmful ultraviolet (UV) radiation, these capsules offer an internal strategy for sun protection. However, the question arises: how do they compare to conventional sunscreen creams?
Sunscreen capsules typically contain ingredients such as nicotinamide (vitamin B3) or antioxidant-rich extracts, like Polypodium leucotomos, a fern extract recognized for its skin-protective properties. While these capsules have gained popularity as a supplementary form of sun defense, experts suggest that their effectiveness remains quite limited.
Limited Protection with an SPF Range of 3-5
Sunscreen capsules are believed to aid in reducing initial skin reactions, such as redness or burning sensations, upon exposure to the sun. Nevertheless, their sun protection factor (SPF) is relatively low, ranging from 3 to 5. This is significantly below the SPF 30 or higher that dermatologists recommend for adequate sun protection. Consequently, sunscreen capsules alone cannot effectively shield the skin from UV damage or prevent photoaging caused by UVA rays.
Although vitamin B3 supplementation has demonstrated a reduction in the risk of non-melanoma skin cancer in adults, the benefits of other components found in these capsules have yet to be conclusively established. Furthermore, excessive use of these supplements may lead to gastrointestinal issues.
A Complementary Tool, Not a Replacement
Sunscreen capsules may offer some benefit to individuals with specific skin conditions like photosensitive eczema, lupus, or actinic keratosis. However, for the general population, these capsules are not a suitable substitute for traditional sunscreens. To ensure comprehensive protection, a combination of methods is advised.
Experts recommend the application of an SPF 30 or higher sunscreen every two to three hours, wearing wide-brimmed hats and UV-blocking sunglasses, and opting for long-sleeved clothing when spending time outdoors. These preventive measures remain the most reliable approach to safeguarding the skin from harmful UV exposure.
