Oxybenzone
Oxybenzone is a chemical also known as benzophenone-3 [1]. It is found in many
sunscreens, hair products and in lesser quantities in nail polish [2]. It is used in sunscreen mainly because it very
effective when it comes to blocking ultraviolet rays from penetrating our skin
[3]. Although it is useful when it comes
to blocking ultraviolet rays from damaging our skin, which can eventually lead
to skin cancer, it has its side effects. Studies have shown that oxybenzone
doesn’t remain on the surface of the skin. It is able to enter our bloodstream
and gets excreted in the urine [1]. Studies in rats have shown that “oxybenzone
and its metabolites [concentrated] in the liver, kidney, spleen and testes and
to a lesser extent in the intestine, stomach, muscle, heart and adrenal glands”
[3]. Researches have also found oxybenzone in water stream. This resulted to
further research to see how it affects animals that lives in water and plants.
They found that oxybenzone to be responsible for dying off of coral reefs [3]. Some
think oxybenzone is ineffective and harmful [4] and if that’s the case then why
is it still used? If we want to protect our skin from sun damage and ourselves
from skin cancer, we need to look for alternatives. The alternative might be to
avoid using sunscreens with oxybenzone and turn into a mineral base [5] or
organic sunscreens. If that is option is not available, try finding sunscreens
with a minimal concentration of oxybenzone.
