Para-aminobenzoic acid, commonly known as PABA or vitamin B10, has a long-standing history in the health and beauty industry, particularly for its sun-protective qualities. While its use in modern sunscreens has declined, its benefits for skin health continue to be a topic of interest. PABA is an organic compound that plays a role in the synthesis of folate in certain microorganisms. Its ability to absorb ultraviolet (UV) radiation, specifically UVB rays, made it a popular ingredient in sunscreens from the mid-20th century onwards. This UVB absorption was believed to protect the skin from sunburn and DNA damage, contributing to its widespread use.

However, concerns regarding allergic reactions and photosensitivity led to a decrease in PABA's popularity as a primary sunscreen ingredient. Regulatory bodies in some regions have restricted its use. Despite this, the unique properties of PABA continue to be explored for various skincare applications. Some proponents suggest that PABA, when taken as an oral supplement, may offer benefits related to skin health, although scientific evidence supporting these claims is often limited or mixed. Early studies indicated potential improvements in certain skin conditions, but more robust research is needed to confirm these effects.

The shift towards PABA-free formulations in many cosmetic products highlights a growing consumer preference for ingredients perceived as gentler or safer. Nevertheless, understanding the historical context and potential benefits of PABA, such as its UV absorption and role in cellular processes, provides valuable insight into the evolution of skincare science. For those interested in exploring ingredients with a history in sun protection and skin care, researching PABA's properties and the reasons behind its evolving role is essential. As with any supplement or cosmetic ingredient, consulting with a healthcare professional is advisable before incorporating it into a regular regimen.
