What is PABA
PABA, or para-aminobenzoic acid, is a chemical compound that was historically used in sunscreens and cosmetics for its UV-absorbing properties. However, its usage has significantly declined due to concerns about potential health risks. PABA can be found in some older sunscreen formulations and hair care products, primarily as a UV filter.
The primary concern with PABA in cosmetic products is its potential to cause skin allergies and sensitivities. Many individuals may experience skin irritation, redness, or allergic reactions when exposed to PABA-containing products. These adverse effects have led to a shift in the cosmetic and sunscreen industry due to its major side effects seen in many individuals.
