What Does Baking Soda Do To Your Skin? Exploring the Science and Safety
Baking soda, while often touted as a natural skincare remedy, can be both beneficial and detrimental; it can exfoliate and reduce oiliness, but its high alkalinity can disrupt the skin’s natural pH balance, potentially leading to irritation and dryness. Understanding what does baking soda do to your skin? is crucial for safe and effective use.
Introduction: The Baking Soda Buzz
Baking soda, also known as sodium bicarbonate (NaHCO3), is a common household ingredient with a wide range of applications, from baking to cleaning. In recent years, it has also gained popularity as a purported skincare solution, with claims ranging from acne treatment to teeth whitening. However, its use on the skin is a subject of debate among dermatologists, and it’s important to separate fact from fiction before incorporating it into your skincare routine.
The Science Behind Baking Soda’s Action on Skin
The effects of baking soda on the skin stem from its alkaline nature. The skin’s natural pH is slightly acidic, typically around 4.5 to 5.5. This acidity helps maintain a healthy skin barrier, protecting against bacteria, irritants, and moisture loss. Baking soda has a pH of around 9, meaning it’s significantly more alkaline than the skin.
When baking soda is applied to the skin, it disrupts this natural pH balance. This disruption can lead to:
- Exfoliation: The alkaline nature of baking soda can loosen the bonds between dead skin cells, promoting exfoliation.
- Reduced Oiliness: Baking soda can absorb excess oil from the skin’s surface, potentially reducing shine and preventing clogged pores.
- Anti-Inflammatory Properties (Limited): Some proponents suggest baking soda has anti-inflammatory properties, but evidence is limited and inconsistent.
Potential Benefits of Using Baking Soda on Skin (With Caution)
While the risks are significant, some argue that baking soda can offer benefits under very specific circumstances:
- Acne Treatment (Spot Treatment Only): Baking soda may temporarily dry out pimples and reduce inflammation, but it’s not a long-term solution.
- Exfoliation (Occasional Use): As a very gentle exfoliant, used extremely sparingly, it might help remove dead skin cells.
- Relief from Insect Bites (Localized Use): A paste of baking soda and water can help soothe itching and irritation from insect bites when applied locally.
The Risks of Using Baking Soda on Skin
The primary risk associated with baking soda is its high alkalinity and how what does baking soda do to your skin? in terms of pH imbalance.
- Irritation and Redness: Disrupting the skin’s pH can lead to irritation, redness, and a burning sensation.
- Dryness and Dehydration: The alkaline nature of baking soda can strip the skin of its natural oils, leading to dryness and dehydration.
- Eczema and Dermatitis Flare-Ups: Baking soda can worsen existing skin conditions like eczema and dermatitis.
- Increased Sensitivity to Sun: A compromised skin barrier is more vulnerable to sun damage.
- Damage to Skin Barrier: Chronic use can weaken and damage the skin barrier, making it more susceptible to infection and environmental damage.
How to Use Baking Soda on Skin (If You Must)
If you choose to use baking soda on your skin, follow these guidelines to minimize the risks:
- Patch Test: Always perform a patch test on a small, inconspicuous area of skin (e.g., inside of your wrist) before applying it to your face or body.
- Dilution: Mix baking soda with water to create a very diluted paste.
- Short Contact Time: Leave the paste on for no more than a few seconds.
- Avoid Sensitive Areas: Do not apply baking soda to the skin around the eyes, mouth, or other sensitive areas.
- Rinse Thoroughly: Rinse the skin thoroughly with water.
- Moisturize: Apply a gentle, hydrating moisturizer immediately after rinsing.
- Frequency: Use extremely sparingly, if at all, no more than once every few weeks.
Alternatives to Baking Soda for Skincare
Safer and more effective alternatives exist for achieving similar results without the risks associated with baking soda:
- Exfoliation: Use gentle chemical exfoliants like AHAs (alpha-hydroxy acids) or BHAs (beta-hydroxy acids).
- Acne Treatment: Opt for proven acne-fighting ingredients like salicylic acid, benzoyl peroxide, or retinoids.
- Oil Control: Use oil-absorbing products containing ingredients like clay or charcoal.
- Soothing Irritation: Apply soothing and anti-inflammatory ingredients like aloe vera, chamomile, or colloidal oatmeal.

Frequently Asked Questions (FAQs)
Will baking soda lighten my skin?
While some people believe baking soda can lighten dark spots or hyperpigmentation, there is no scientific evidence to support this claim. In fact, its abrasive nature can irritate the skin, potentially worsening hyperpigmentation in the long run.
Can baking soda cure acne?
Baking soda might temporarily dry out acne blemishes, but it is not a cure for acne. Its harshness can actually exacerbate inflammation and lead to further breakouts by disrupting the skin’s natural barrier.
Is baking soda safe for sensitive skin?
Absolutely not. Baking soda is not recommended for sensitive skin. Its high alkalinity can cause significant irritation, redness, and dryness, potentially leading to a flare-up of existing skin conditions.
Can I use baking soda to remove blackheads?
Baking soda might help to loosen blackheads due to its exfoliating properties, but there are much safer and more effective methods available. Salicylic acid is a more gentle and effective option for unclogging pores.
What happens if I leave baking soda on my skin for too long?
Leaving baking soda on your skin for too long can cause severe irritation, redness, burning, and dryness. In some cases, it can even lead to chemical burns.
Can baking soda help with sunburn?
While a baking soda paste might provide temporary relief from sunburn by soothing inflammation, it is not a substitute for proper sun protection and aftercare. Aloe vera or calamine lotion are generally preferred.
Is baking soda safe to use during pregnancy?
Topical use of baking soda is generally considered safe during pregnancy, but it’s always best to consult with your doctor or dermatologist before using any new skincare products.
Can I use baking soda as a deodorant?
Baking soda can absorb odor, but using it directly on the skin as a deodorant can cause irritation, especially in the sensitive underarm area. Consider using a baking soda-free deodorant or natural alternatives like magnesium hydroxide.
Does baking soda expire?
Baking soda does not technically expire, but its effectiveness may decrease over time. Store it in a cool, dry place to maintain its potency.
Can I mix baking soda with other skincare ingredients?
Mixing baking soda with other skincare ingredients is generally not recommended. Its high pH can interfere with the effectiveness and safety of other products, potentially leading to irritation or unwanted chemical reactions.
How often can I use baking soda on my skin?
Given the risks, using baking soda on the skin is not recommended as a regular part of your skincare routine. If you choose to use it, do so extremely sparingly and infrequently (no more than once every few weeks) to minimize the risk of irritation.
What should I do if my skin is irritated after using baking soda?
If your skin becomes irritated after using baking soda, immediately rinse the area thoroughly with cool water. Apply a gentle, hydrating moisturizer and avoid using any harsh or irritating products until the irritation subsides. If the irritation is severe or persists, consult a dermatologist. Knowing what does baking soda do to your skin? is the first step toward preventing damage in these instances.
