Description: Butyl methoxydibenzoylmethane is a white or pale yellow synthetic compound. It is used as a UVA absorber in sunscreen products. It has been safely and extensively used in cosmetics and sunscreens for decades.

We include it with ethylhexyl methoxycinnamate, a UVB screening compound. Combined, these compounds are highly effective in protecting from sun damage.

Different frequencies of UV light can cause varying types of damage to our skin. UVA exposure penetrates the skin and causes degradation of collagen and elastin fibres, causing the skin to be damaged from the inside out. If you are not sufficiently protected, UVB exposure causes burning and redness. It also encourages skin to produce the pigment, melanin, which the body produces to protect itself. A tan is a sign of damage related melanin production.
