Detailed answer

Baking soda has mild exfoliating properties that can help to improve the appearance of dark spots by removing dead skin cells. Its alkaline nature may also have a slight lightening effect. However, it is crucial to note that baking soda can be abrasive and may cause irritation, redness, or even damage to the skin if used incorrectly. It is not a scientifically proven or recommended treatment for dark spots. For more effective and safer alternatives, it is advisable to consult a skincare professional.
