<Tear Stain Remover Powder> For removing tear stains (for dogs and cats) This is a grooming powder for dogs and cats. Individual results may vary, so this is just a reference, but it did have a whitening effect on my pet. More frequent application seems to prevent the powder from soaking into the skin, which seems to reduce skin irritation. For detailed instructions, please search for "grooming powder". Reference: Instructions on the container (Google Translate) Using a brush or fingertips, gently apply the powder and blend evenly along the direction of hair growth. Allow to absorb naturally. Repeat daily until the stain disappears (usually 7 days). Apply weekly to prevent recurrence. For best results, apply after using Eye Envy Tear Stain Remover Solution. Capacity: 14g (0.5oz) This is an authentic product purchased from the official US website. *Please note that the packaging may have scratches or marks due to being an imported product.
