Is it bad to use baking soda on your skin?

As a skincare expert with years of experience in the field, I can tell you that the use of baking soda on the skin is a topic that has been widely debated. It's essential to understand the properties of baking soda and how it interacts with the skin to determine whether it's a good or bad idea to use it. Baking Soda Properties and Skin pH: Firstly, let's discuss the pH level. The pH scale ranges from 0 to 14, with 7 being neutral. Anything below 7 is considered acidic, and anything above 7 is alkaline or basic. The average pH of human skin is approximately 5.5, which is slightly acidic. This slightly acidic environment is crucial for maintaining the skin's natural barrier and preventing the overgrowth of harmful bacteria. Baking soda, or sodium bicarbonate, has a pH of around 9, making it quite alkaline. When something with a significantly higher pH comes into contact with the skin, it can disrupt the skin's natural pH balance, potentially leading to dryness, irritation, and even damage to the skin's protective barrier. Skin Irritation and Damage: Using baking soda on the skin can cause irritation, especially for those with sensitive skin or pre-existing skin conditions like eczema or rosacea. The abrasive nature of baking soda can lead to micro-tears in the skin, increasing the risk of infection and inflammation. Moreover, frequent use of baking soda can lead to permanent damage. The skin's barrier is its first line of defense against environmental aggressors. When this barrier is compromised, the skin becomes more susceptible to damage from UV rays, pollutants, and other harmful substances. Exfoliation and Baking Soda: Some people use baking soda as a DIY exfoliant due to its mild abrasive qualities. While it's true that exfoliation can help remove dead skin cells and promote a brighter complexion, baking soda can be too harsh for regular use, particularly on the delicate skin of the face. Alternatives to Baking Soda: For those looking for a more gentle exfoliating option, there are many alternatives available. Products containing alpha hydroxy acids (AHAs) like glycolic acid or beta hydroxy acids (BHAs) like salicylic acid can provide exfoliation without the risk of damaging the skin's barrier. These ingredients are specifically formulated to be effective and safe for use on the skin. When to Use Baking Soda: That being said, baking soda is not entirely without its uses in skincare. It can be beneficial for certain applications, such as a spot treatment for acne or body odor. However, these uses should be limited and not applied over large areas of the skin or for extended periods. Conclusion: In conclusion, while baking soda has its place in the kitchen and for some specific uses, it is not recommended for regular use on the skin due to its high pH and potential for causing irritation and damage. It's always best to use products that are specifically formulated for skincare to ensure they are safe and effective.

This is not good! In fact, it's really, really bad. Baking soda is way too harsh to be safe for skin--the pH of your skin is about 5.5, and baking soda is a whopping 9. ... And the more frequently you use it, the more permanent damage it does to the skin.
