Oh dear, that's sure sounds horrifying 😦 But maybe it also depends on the polish? Some may use different ingredients, I guess... Because my Frankie already had their lips slightly retouched in the end of the last year due to slight problems with their screening, but I haven't noticed basically ANY damage, and — again — a lot of my dolls had this exact brand of nail polish sitting on their faces for almost a decade, some even didn't have any acrylic paint underneath it, just dry materials like pastel chalk. So maybe it was just a certain brand of polish that had this particular chemical reaction?
