Paba

PABA (para-aminobenzoic acid) is an organic ultraviolet filter that has been used in sunscreen products for several decades. It works by absorbing ultraviolet radiation, particularly in the UVB spectrum, and converting it into heat to prevent it from reaching the skin.As a chemical sunscreen ingredient, PABA belongs to the class of organic filters that are designed to be incorporated into skincare formulations to provide photoprotection. Its use in cosmetics has evolved over time as newer filter technologies have been developed.

PABA functions as an organic ultraviolet filter by absorbing UVB radiation. When UV light strikes the ingredient, it is absorbed and converted into thermal energy (heat), which is then released from the skin rather than penetrating deeper into the epidermis.For effective protection, PABA must be used in formulated sunscreen products at appropriate concentrations and applied generously to all sun-exposed areas of the skin.

If using a sunscreen containing PABA, apply generously to all sun-exposed skin and reapply every two hours, or more frequently after swimming or sweating. For optimal protection, combine sunscreen use with other photoprotective measures such as protective clothing, hats, and seeking shade during peak UV hours (typically 10am to 4pm).

PABA has been used in cosmetics for over 40 years. Some individuals may experience contact sensitivity or allergic reactions to PABA.
