Mineral vs. Chemical Sunscreen: The Reef Damage, Aerosol Risks & SPF Myths Nobody's Talking About with Shannon Kenner of Waxhead Sun Defense

#34 Mineral vs. Chemical Sunscreen: The Reef Damage, Aerosol Risks & SPF Myths Nobody's Talking About with Shannon Kenner of Waxhead Sun Defense

☀️ mineral or chemical...does your sunscreen choice actually matter? we sat down with Shannon Kenner, co-founder of Waxhead Sunscreen, to find out.

Shannon and his wife, Kari, started  @gowaxhead  after their son's eczema pushed them to dig into what's actually in sunscreen and what they found changed everything about how their family approaches sun protection.

☀️we're diving into:
+ why "reef safe" isn't a regulated term (and what to actually look for)
+ oxybenzone swapped for avobenzone, same problem, different name
+ how aerosol sunscreens may be contaminated with benzene, a known carcinogen
+ the real difference between nano and non-nano zinc oxide
+ why zinc oxide doesn't expire (and chemical sunscreen does)
+ the white cast "problem" and why Shannon calls it "the badge of smart living" + tattoos, melasma and mineral sunscreen...does it work differently?
+ SPF science explained simply- why 30 is basically always enough
