Sydney Sweeney's new soap bar made with her real bathwater, launched with Dr Squatch, has gone viral and sparked widespread discussion about hygiene and celebrity marketing ethics

Sydney Sweeney is the face of a limited edition Dr. Squatch soap bar, and her bathwater is listed as an ingredient.

The medium-grit soap is made from pine bark extract, exfoliating sand and droplets of the “Euphoria” star’s bathwater. The scent -- in a nod to Sweeney’s Pacific Northwest roots -- combines pine, Douglas fir and earthy moss…and perhaps a trace of Sweeney herself?
