1- Preservatives are usually considered safe if you stick to their recommended usage limits. But how does this rule apply to the whole product? Let’s think about it: If I’m slathering on a moisturizer sparingly on my face but going all out on my body—like, ten times more—then I’m basically soaking up those preservatives tenfold!

Also, that particular product is only one of the many preservative-containing cosmetics/detergents we use everyday. So, what really backs up these limits? How can we guarantee safety regarding their potential genotoxicity with such high levels of use? Not obsessed with that “preservative-free, super organic, ultra natural” lifestyle but I’m simply curious about this topic.

2- The skin tends to be slightly acidic, which is why products are typically formulated within the pH range of 5 to 6. Why isn’t a neutral pH, like 7 or even 8, as favored? Do we compromise the pH balance of our skin by showering, which involves rinsing with tap water at pH 7? And what about swimming in those thermal waters or seawater, which can have pH levels reaching up to 8.2?
