WHAT TO AVOID

Element - - LIFE STYLE -

Oxy­ben­zone is a syn­thetic es­tro­gen which has been linked to hor­mone dis­rup­tion and when ex­posed to sun­light, cre­ates harm­ful free rad­i­cals that de­stroy or in­hibit the skins nat­u­ral de­fences against sun­light. Retinyl palmi­tate is a type of vi­ta­min A com­monly found in sun­screens. A joint report by the US En­vi­ron­men­tal Pro­tec­tion Author­ity and the Na­tional Tox­i­col­ogy Pro­gram con­cluded that retinyl palmi­tate led to the early on­set and larger amount of skin le­sions and squa­mous (can­cer­ous) cell tu­mours. Parabens are preser­va­tives com­monly found in sun­screen and a range of cos­met­ics. Some ev­i­dence sug­gests parabens can mimic es­tro­gen and in some cases they’ve been found in breast can­cer tu­mours. Fra­granced sun­screens con­tain a high amount of chem­i­cals that can trig­ger asthma and, like parabens, some have been shown to mimic es­tro­gen and make breast can­cer cells grow in lab­o­ra­tory stud­ies. Ex­pired sun­screens are likely to have lost some of their ef­fec­tive­ness. Use-by dates are de­ter­mined by how long the sun­screen will re­tain its ef­fi­cacy and safety, which is typ­i­cally any­where up to three years.
