There is tons of anecdotal evidence claiming the benefits of baking soda for acne and acne scars. However, there is no scientifical evidence that proves these benefits of baking soda, and it is not a recommended medical treatment for acne. It is a folk remedy for teeth-whitening and soothing mild acne, rashes, indigestion, and bug bites. In fact, baking soda can do more harm than good. Therefore, you need to be extremely careful when using baking soda for acne and pimples. In this article, we have discussed everything you need to know about using baking soda on your skin and for acne.

Can You Use Baking Soda For Acne? Is It Effective?

Anecdotal evidence claims that baking soda is effective for acne. However, there hasn’t been any research to evaluate whether baking soda works for acne or not. The U.S. Food and Drug Administration has not approved this popular home remedy for acne. The advocates of this popular home remedy believe that baking soda may help in minimizing your acne, depending on your skin type.

It is claimed that baking soda has a drying effect on the skin, and this property helps shrink the zit and reduce inflammation. It is also said to help in the following ways:

  • Baking soda has anti-inflammatory properties that help soothe swelling and redness. It not only helps calm flare-ups, but also soothes rashes, irritation, and sunburn.
  • Baking soda is a physical exfoliant. It has fine particles that dislodge dirt and dead skin cells from your pores. It also causes relatively less irritation than most exfoliators while being more efficient.
  • It not only helps fight and prevent acne but also minimizes the appearance of acne scars and pigmentation.
  • It helps absorb the excess oil from your skin. This, in turn, dries out pimples and blemishes, helping them heal faster.

If you have oily or extremely oily and acne-prone skin, you may try using baking soda. However, there is no scientific research that proves that baking soda is good for acne or your skin, so you need to be very careful while using this ingredient. Baking soda can cause severe discomfort if it does not suit your skin or if you overuse it. Check them out in the next section.

Are There Any Side Effects Of Using Baking Soda For Acne?

Yes, there are a few risks associated with using baking soda on your skin. Anything in excess is not good for the skin. The same goes for baking soda. If you use it too frequently or if it does not suit your skin, the following side effects may occur:

  • It might damage the protective barrier of your skin and worsen your acne. This is because the pH of your skin is slightly on the acidic side (which is crucial for maintaining a balance). When you apply baking soda, it removes the acidic protective barrier and leaves it vulnerable to breakouts and bacteria.
  • It can irritate your skin. Baking soda has a drying effect, and if you use it on your skin (or use it too frequently), it may irritate the skin and cause redness, breakouts, rashes, and burning sensation.
  • It might overdry your skin and cause inflammation.

The average natural pH of the skin (without showering and using any cosmetic products) is 4.7. It usually ranges between 4.5 and 5.5. On the pH scale, anything below 7 is acidic and anything above 7 is alkaline. While our skin is acidic, baking soda has a pH of 9, which is alkaline. When you apply an alkaline ingredient to your skin, it naturally strips away its natural oils, leaving it exposed to UV rays, bacteria, and environmental damage.

Although it is not recommended, you can try a few baking soda recipes to control inflammation. Make sure that you only use the recommended amount of baking and do not exceed that. Also, do not follow any of these recipes more than once a week.
