That claim is not supported by good evidence, and using baking soda on your face overnight can actually irritate your skin.
Why to be cautious:
- Baking soda (sodium bicarbonate) is alkaline, while healthy skin is naturally slightly acidic.
- Regular application can disrupt the skin barrier, leading to:
- Dryness
- Redness
- Irritation
- Increased sensitivity
- There is no reliable scientific evidence that a baking-soda cream removes wrinkles, tightens skin, or eliminates age spots.
For concerns like wrinkles and dark spots, treatments with better evidence include:
- Daily broad-spectrum sunscreen (SPF 30 or higher)
- Retinoids/retinol
- Vitamin C products
- Niacinamide
- Azelaic acid (for some types of pigmentation)
- Professional treatments from a dermatologist when appropriate
If you found this in a social media post, it’s best to treat it as a marketing or engagement claim rather than a proven skincare remedy. If you’d like, I can also explain what ingredients in a skincare product actually have evidence for reducing wrinkles or fading spots.
