Baking soda is alkaline, while healthy facial skin has a naturally acidic surface.
Applying baking soda directly to the skin can cause:
- Dryness
- Burning or stinging
- Redness
- Irritation
- Disruption of the skin barrier
Scrubbing it into the skin can make irritation even worse.
And although the skin might temporarily look different after washing off a mask, that is not the same as removing pigmentation or reversing wrinkles.
What About Under-Eye Circles?
Under-eye darkness can have many causes, including genetics, skin pigmentation, visible blood vessels, shadows caused by facial anatomy, allergies, and lack of sleep.
Baking soda cannot reliably eliminate these causes.
The skin around the eyes is also particularly delicate, so household powders and DIY acids or alkaline ingredients should not be used there.
What About Wrinkles?
Moisturizing can temporarily make fine lines look less noticeable by improving skin hydration.
For longer-term wrinkle care, sunscreen and evidence-based ingredients such as retinoids can be considerably more useful than a baking-soda mask.
When to Have a Dark Spot Checked
Not every dark spot is simply an age spot. If a spot is new, changing in size or color, bleeding, crusting, itching persistently, or looks noticeably different from your other spots, have it examined by a dermatologist rather than trying to remove it at home.
Final Thoughts
Baking soda may be useful in the kitchen, but it is not a proven seven-minute treatment for dark spots, wrinkles, or under-eye circles. Using it on the face can actually irritate the skin and make the skin barrier less healthy.
For brighter and healthier-looking skin, stick with gentle cleansing, consistent moisturizing, sun protection, and properly formulated skincare products.
