Mostly false.
Most all skincare doesn’t penetrate the skin deeply enough to be absorbed into the bloodstream, however some chemicals (like pthalates) become airborne after being applied to the skin and are inhaled, entering the bloodstream that way. Other compounds in skincare *can* be absorbed by the skin, but it’s only those compounds, not the entire beauty product.
So, generally false.
