Claims that baking soda can remove dark spots, wrinkles, and dark circles are not supported by good scientific evidence. In fact, applying baking soda to your face can do more harm than good.
Why baking soda isn’t recommended for facial skin
Baking soda is highly alkaline (pH around 8–9), while healthy skin is naturally slightly acidic (pH around 4.5–5.5). Using baking soda on your face can:
- Disrupt the skin’s protective barrier.
- Cause dryness, irritation, and redness.
- Worsen sensitive skin conditions like eczema or acne.
- Increase the risk of post-inflammatory dark spots in some people.
What works better
For dark spots (hyperpigmentation):
- Daily broad-spectrum sunscreen (SPF 30 or higher) is one of the most effective ways to prevent spots from getting darker.
- Ingredients with evidence for improving pigmentation include:
- Azelaic acid
- Tretinoin (prescription)
- Hydroquinone (where appropriate and often under medical supervision)
- Vitamin C
- Niacinamide
For wrinkles:
- Daily sunscreen.
- Retinoids (such as tretinoin or over-the-counter retinol).
- Moisturizers that contain ingredients like hyaluronic acid or ceramides can improve the appearance of fine lines by hydrating the skin.
For dark circles:
The best treatment depends on the cause. Dark circles may result from genetics, allergies, lack of sleep, aging, or pigmentation. Helpful measures may include:
- Getting enough sleep.
- Treating underlying allergies if present.
- Using sunscreen around the eyes.
- Products containing caffeine or retinoids (used cautiously around the eye area) may help some people.
If you already used baking soda
If your skin becomes irritated after using baking soda:
- Stop using it.
- Wash it off with lukewarm water.
- Apply a gentle, fragrance-free moisturizer.
- Avoid harsh exfoliants until your skin has recovered.
If irritation is severe or doesn’t improve, seek advice from a healthcare professional.
Overall, baking soda is better suited for household cleaning and baking than for facial skincare. Evidence-based skincare ingredients are more likely to improve dark spots and wrinkles while being safer for your skin when used correctly.
