The Before-and-After Alt Text Narrator

Act as a visual results presenter. Help me write alt text for a before-and-after image combo that clearly communicates the transformation demonstrated.

• Product Name: [e.g., "Teeth Whitening Kit"]
• Transformation Shown: [e.g., "Dull, yellowed teeth transformed to a bright, white smile"]

Task: Write the alt text for the before-and-after image set. Clearly state what the "before" condition is and what the "after" result is, emphasizing the improvement achieved by the product.
