The Swedish royal, 42, who is the youngest child of King Carl XVI Gustaf and his wife Queen Silvia , revealed last month she was launching a natural skincare line called MinLen.
Crown Princess Victoria, 47, was accompanied at the Royal Palace in the Swedish capital by her husband Prince Daniel, 51, and her younger brother Prince Carl Philip.
