When sunscreen lotion first came on the market, it was marketed as a way to prevent sunburn. Over the years, however, the marketing angle changed when manufacturers realized there is more money to be made by claiming their products protect against dreaded skin cancer.
Only problem is that while sunscreen can protect you against sunburn, there is no evidence it will protect you from skin cancer. In fact, the evidence suggests the opposite – that sunscreens have partially caused an increase in skin cancer!
One of the most common ingredients in commercial sunscreens is a chemical known as PABA or padimate-O, which is known to produce genetic mutations that can lead to cancer. Even more incredibly, PABA becomes aggressively carcinogenic only when it is illuminated by UV light. In other words, exposure to sunlight is what causes this chemical to attack your DNA.
According to a study published in the journal Mutation Research :
“Any padimate-O in contact with the cells substantially increases indirect damage [to DNA]… We estimate that applying an SPF-15 sunscreen which contains padimate-O to human skin followed by exposure to only 5 minimum erythemal doses (MED) of sunlight could… increase [DNA] strand breaks in cells under the epidermis by at least 75-fold compared to exposure to 1 MED in the absence of sunscreen.”
You should certainly think twice before slathering chemical sunscreens on your skin. Whenever possible, protect yourself from sunburn with clothing and shade. And when you do need to use sunscreen, use one with natural ingredients, with the physical barrier zinc oxide as its active ingredient.[Ed.
