Mainstream Sunscreens
Many commercial sunscreen products contain ingredients which latest research reveals may cause serious problems:
- Octyl-methoxycinnamate – produces free radicals (singlet molecular oxygen) known to be toxic to cells (1)
- Titanium dioxide – causes DNA damage (the cells genetic material) due to superoxide radicals, active oxygen radicals and hydroxyl radicals when exposed to light (2) (3) (4)
- Oxybenzone – is rapidly oxidised in the presence of light and inactivates important antioxidant systems in the skin (the skin’s natural protection system) (5)
- PABA – produces free radicals in the presence of light (1)
- Cinoxate – causes DNA damage (sister chromatid exchanges) (6)
- Padimate-O – produces free radicals in presence of light (singlet molecular oxygen) and substantially increase indirect damage (strand breaks in DNA) when in contact with cells (1) (7)
- Dibenzoylmethane and Parsol 1789 – produces free radicals responsible for direct DNA damage (strand breaks) (8)
- Methyl sinapate – causes DNA damage (chromosome aberrations and sister chromatid exchanges) (9)
- Phenylbenzimidazole sulphonic acid and 2-phenylbenzimidazole – acts as photosensitisers of DNA damage when exposed to sunlight or UV- B radiation (10)
