The myth that "60% of what's applied to your skin is absorbed into your bloodstream" is one of my pet peeves. It's so far from the truth, and it's cited with such an air of authority that it really ticks me off.

There are tons of micellar waters on the market now, many of them with similar active ingredients. The essential ingredients in any micellar water are: Water (obviously) and One or more surfactants. Surfactants are cool ingredients that I've written about a lot (including in my guest post on The Toast). They're useful molecules with a hydrophilic head that's attracted to water (and repels oil), and a lipophilic tail that's attracted to oils and grease (and repels water).

I recently started using a prescription tretinoin cream, a generic version of Retin-A (Stieva-A). Tretinoin is probably THE most popular and evidence-supported retinoid (vitamin A derivative) ingredient in skincare.
