Age spots, also known as liver spots or sun spots, are flat brown, gray, or black patches that commonly appear on areas of the skin exposed to the sun over many years. They are especially common on the face, hands, shoulders, and arms. While harmless, many people look for ways to reduce their appearance and achieve a more even skin tone.
One popular home remedy often shared online is baking soda. Supporters claim that baking soda can help exfoliate the skin, remove dead skin cells, and gradually lighten age spots. But what does science actually say?
Baking soda, or sodium bicarbonate, has mild abrasive properties that can help exfoliate the skin’s surface. By removing dead skin cells, it may temporarily make the skin appear brighter and smoother. Some people create a paste by mixing baking soda with water and applying it directly to age spots for a few minutes before rinsing.
