Uvinul A Plus
Also known as: Diethylamino hydroxybenzoyl hexyl benzoate
What It Does
A powerful UVA filter with excellent photostability. Helps prevent the deep skin damage that leads to premature aging.
Uvinul A Plus (diethylamino hydroxybenzoyl hexyl benzoate) is a highly effective UVA filter, particularly for long UVA rays (UVA1) that penetrate deepest into skin and cause aging. It is one of the most photostable organic UV filters available and provides excellent protection against photoaging. It is approved in Europe, Asia, and other regions but not in the United States.
Uvinul A Plus addresses a critical gap in sun protection: while many filters protect against UVB and UVA2, UVA1 protection has historically been lacking. UVA1 rays penetrate deeply into the dermis, causing collagen breakdown and long-term aging. Uvinul A Plus specifically targets this range, making it valuable for anti-aging sunscreens.
Japanese sunscreens, which are known for their high PA ratings (PA++++ indicating superior UVA protection), frequently include Uvinul A Plus. Brands like Anessa, Allie, and Skin Aqua use it to achieve maximum UVA protection in their premium formulations. The ingredient represents the cutting edge of photoaging prevention.
Absorbs long UVA rays (UVA1) that cause deep skin damage and photoaging. Highly photostable, does not degrade under sun exposure.
