Baking soda is sometimes used in home skincare, but it’s important to be careful: it can irritate the skin and damage the skin barrier if used too often or too strongly. It may temporarily help with mild dullness or surface oil, but it is not a proven treatment for dark spots (hyperpigmentation).
Still, here is how people commonly use it and what benefits (and risks) it may have.

🧴 Baking Soda for Dark Spots on Face
⚠️ Important Reality First
Dark spots (sun spots, acne marks, or melasma) usually need:
Sunscreen
Vitamin C or niacinamide
Dermatology treatments in some cases
Sodium bicarbonate is alkaline, while skin is naturally slightly acidic. This means overuse can:
Dry out skin
Cause redness
Make pigmentation worse in sensitive skin
