Baking soda is a common household ingredient found in kitchens around the world. Known scientifically as sodium bicarbonate, it is widely used in baking, cleaning, and deodorizing. In recent years, social media has popularized baking soda as a DIY skincare treatment, claiming it can reduce dark spots, remove wrinkles, clear acne, and brighten the skin.
But does baking soda really deserve a place in your skincare routine?
Before applying it to your face, it’s important to understand both the potential benefits and the possible risks.
What Is Baking Soda?
Baking soda is a white crystalline powder with alkaline properties. It has a pH of approximately 8.3, making it significantly more alkaline than healthy skin.
Human skin naturally maintains a slightly acidic pH between 4.5 and 5.5. This acidic environment helps protect against bacteria, irritation, and moisture loss.
Because of this difference in pH, dermatologists often recommend caution when using baking soda directly on the skin.
Why People Use Baking Soda on Their Face
Many homemade beauty recipes include baking soda because it is inexpensive and readily available.
Common claims include:
- Exfoliating dead skin cells
- Brightening dull skin
- Reducing the appearance of dark spots
- Improving skin texture
- Helping remove excess oil
While some users report temporary improvements, results vary greatly from person to person.
