The headline “4 Ways to Erase Age Spots with Baking Soda” is misleading. There is no good evidence that baking soda safely removes true age spots, and applying it repeatedly can irritate the skin. Irritation can actually make pigmentation worse. (American Academy of Dermatology)
What you should know
1. Baking soda + water
Often promoted as a scrub or paste, but I wouldn’t recommend it. It can be drying and irritating, especially if rubbed into the skin.
2. Baking soda + lemon juice
This is an especially poor choice. Lemon can irritate the skin, and combining irritating ingredients can leave pigmentation worse rather than better.
3. Baking soda + toothpaste
Another viral remedy with no established benefit for age spots. It can cause irritation or dermatitis.
4. Baking soda as an exfoliant
Physical scrubbing doesn’t remove the underlying pigment safely. Repeated irritation may worsen uneven pigmentation.
✅ What actually works better
For genuine sun-related age spots, dermatologists use treatments such as prescription retinoids, chemical peels, cryotherapy, laser/IPL, and microdermabrasion, depending on the individual spot and skin type. (American Academy of Dermatology)
The simplest daily step is broad-spectrum SPF 30+ sunscreen on exposed skin, including the hands. Sun protection helps prevent new spots and keeps existing pigmentation from becoming darker. (American Academy of Dermatology)
⚠️ One important warning
Don’t assume every brown spot is an “age spot.” Some skin cancers and precancerous lesions can resemble age spots. The American Academy of Dermatology recommends having suspicious spots evaluated before attempting to remove them yourself. (American Academy of Dermatology)
Bottom line: Baking soda isn’t a proven age-spot treatment. A gentle skincare routine plus sun protection—and, if needed, dermatologist-directed treatment—is much safer and more effective.
