Age spots—also known as dark spots, sun spots, or hyperpigmentation—are a common skin concern as we grow older. They often appear on the face, hands, neck, and shoulders, especially after years of sun exposure. While they are harmless, many people look for gentle, affordable ways to improve skin tone and regain a more youthful glow.
One ingredient that frequently appears in DIY skincare discussions is baking soda (sodium bicarbonate). When used correctly and cautiously, baking soda may help exfoliate the skin and improve its appearance, which can make dark spots look lighter over time.
This article explores four safe, supportive ways baking soda can be used in skincare routines, explains what it can and cannot do, and shares important precautions to protect your skin.
⚠️ Important note: Baking soda does not medically “erase” age spots. It may help improve surface appearance when used occasionally and gently. Always patch test and consult a dermatologist for persistent or severe pigmentation.
What Are Age Spots and Why Do They Appear?
Age spots are flat, darkened areas of skin caused by excess melanin production. Common causes include:
-
Long-term sun exposure (UV damage)
-
Natural aging
-
Hormonal changes
-
Genetics
-
Inflammation or skin injury
They become more common after age 40, but younger people can develop them too—especially if sun protection is inconsistent.
Can Baking Soda Really Help with Age Spots?
Baking soda has mild exfoliating and pH-balancing properties. When used sparingly, it may:
-
Remove dead skin cells
-
Improve skin texture
-
Enhance brightness
-
Help skincare products absorb better
However, baking soda is alkaline, while healthy skin is slightly acidic. Overuse can damage the skin barrier, so moderation is critical.
