As the methods of sun protection evolve, a new contender has entered the scene—sunscreen capsules.

Unlike traditional creams, which either absorb or reflect harmful ultraviolet (UV) rays, these capsules offer an internal approach to sun protection. But how do they compare to regular sunscreen creams?

Sunscreen capsules typically contain ingredients like nicotinamide (vitamin B3) or antioxidant-rich extracts such as Polypodium leucotomos, a fern extract known for its skin-protective qualities. While these capsules have become popular as a supplementary form of sun protection, experts suggest their effectiveness is still quite limited.

Limited protection with SPF between 3-5

Sunscreen capsules are believed to help reduce initial skin reactions, such as redness or burning, when exposed to the sun. However, their sun protection factor (SPF) is relatively low, ranging from 3 to 5. This is far from the SPF 30 or higher that dermatologists recommend for adequate sun protection. As a result, sunscreen capsules alone cannot effectively shield the skin from UV damage or prevent photoaging caused by UVA rays.

Although vitamin B3 supplementation has been shown to reduce the risk of non-melanoma skin cancer in adults, the benefits of other ingredients in these capsules have yet to be conclusively proven. Additionally, overuse of these supplements may lead to gastrointestinal issues.

A complement, not a replacement

Sunscreen capsules could be helpful for individuals with skin conditions like photosensitive eczema, lupus, or actinic keratosis. However, for the general public, these capsules are not a suitable replacement for traditional sunscreens. To ensure full protection, a combination of methods is advised.

Experts recommend applying an SPF 30 or higher sunscreen every two to three hours, wearing wide-brimmed hats and UV-blocking sunglasses, and choosing long-sleeved clothing when outdoors. These preventive measures remain the most reliable approach to safeguarding skin from harmful UV exposure.
