Who should avoid applying baking soda to their face?
Avoid this product if you suffer from eczema, rosacea, active inflammatory acne, very dry or dehydrated skin, or if you have a history of sensitivity to skincare products. Also avoid using it on broken skin, around the eyes, during pregnancy, or if you have conditions such as diabetes that affect wound healing.
