Claims like “Prepare the baking soda cream and apply it before bed. Goodbye wrinkles and blemishes” are not supported by good scientific evidence.
Here’s what is known:
- Baking soda is not a proven anti-wrinkle treatment. It does not stimulate collagen or reverse skin aging.
- It is alkaline, while healthy skin is naturally slightly acidic. Applying baking soda regularly can disrupt the skin barrier, leading to:
- Dryness
- Irritation
- Redness
- Increased sensitivity
- Potential worsening of eczema or acne in some people
What actually works for wrinkles and dark spots?
For wrinkles:
- Daily broad-spectrum sunscreen (SPF 30 or higher) is one of the most effective ways to prevent further aging.
- Retinoids (such as retinol or prescription tretinoin) have strong evidence for improving fine lines over time.
- Moisturizers containing ingredients like hyaluronic acid can temporarily make skin appear smoother.
For dark spots (hyperpigmentation):
- Sunscreen to prevent spots from becoming darker.
- Ingredients with evidence include vitamin C, niacinamide, azelaic acid, and retinoids.
- Persistent pigmentation may benefit from evaluation by a dermatologist, who can recommend stronger treatments if appropriate.
If you’re looking for an inexpensive nighttime skincare routine, I can suggest one based on your skin type (dry, oily, combination, or sensitive).
