I wear La Roche Posay antethelios 50 all year round on face, neck and chest. Most of the time I have no issues but I find that on humid/sweaty days it leaves a yellowish mark on the neckline of T-shirts that seems impossible to get out. Any recommendations for factor 50 for sensitive skin that does not stain clothing please? And/Or tips on products which will remove the staining? I have soaked overnight in vanish and washed on really long washes with vanish.
