How to Use Baking Soda to Lighten Skin

Baking soda (chemical name sodium bicarbonate) has multiple health benefits and is used for many different purposes. Its versatility is in part due to the fact that it is amphoteric, which means it reacts with both bases and acids. While this chemical element is used in laboratories and factories, it is also mild enough to be used on the human body, especially if you don't have sensitive skin, in which case you can use turmeric. If this is the case and you want to clarify your skin a little you can use bicarbonate as a home skin lightening kit. At oneHOWTO we tell you the information you need to know how to use baking soda to lighten skin, clearly and simply.

Steps to follow:

While baking soda is regularly advertised for toothpaste to encourage the whitening of teeth, it is less common to see this ingredient promoted in facial scrubs. However, bicarbonate of soda has different elements which can be very beneficial to your skin if used properly. Some of these benefits include the ability to neutralize the pH levels of the skin, used as a replacement for mouthwash and even acting as a deodorizer. When used on the skin, it not only brings balance, but it acts as a skin lightener and the small crystals which give it a mildly abrasive consistency work as a great natural exfoliant. You can start the skin lightening treatment, depending on the sensitivity of your skin, and experiment up to 3 times a week. If the desired effect is reached, you can shelve it and reintroduce it again in the future once the effects fade away.

Before you start, you should check to make sure that you won't get an adverse reaction to the baking soda by putting a little on your skin and seeing if it reacts. When you do experiment with using bicarbonate of soda for your skin, start with smaller amounts and then gradually increase them rather than using a whole lot at the beginning. As we will be using it on our face, be careful not to get it near the eye area as it can react badly and cause irritation. The same goes for open sores or broken skin, so be careful if you have any of these on your face.


The first step in lightening the skin is to use baking soda as an exfoliant. Sodium bicarbonate not only exfoliates thanks to its mild abrasive quality, but the pH neutralizer. Like diet, exercise, personal relationships and just about everything else that makes this world go round, a balance is necessary. The reason why we have a balance in the skin is because it acts as a protective layer against dirt and infection. The perfect pH level for skin is 5.5 which is actually slightly acidic, but as baking soda is amphoteric, it can help whether or not it is too alkaline or acidic.

To know if it is too alkaline, you will see that the skin becomes patchy and dry or easily irritated. If it is too acidic, you may have oily skin and a greater chance of acne or other blemishes. To use baking soda on your skin, create a paste by using a 2:1 ratio of bicarbonate of soda to water. Rub this on your skin and leave it on for 30 seconds to 1 minute then rinse well with water. Don't leave it on too long or it may remove this protective barrier altogether. This will be counterproductive when it comes to making your skin lighter as it may just make it redder.


The fact that the pH of bicarbonate is neutralizing helps treat acne and blackheads as it should not cause irritation. However, you must be cautious when using baking soda to not apply it in the eye area and so to avoid irritation of the eyes and eyelids. This treatment, when applied to the skin of the face, must be done only once daily and at most three times a week. In other parts of the body you need not be so careful with the times of application as the skin is tougher. Being cautious is always better than going in full blast and doing something which might affect your skin negatively, so ensue to test your skin first and do not leave it on for too long. Another remedy that works for both skin lightening and acne is fuller's earth.


Exfoliation will help remove cellular damage in patches of darkened skin, but to get a bleach effect that does not dry and damage your skin you can apply the bicarbonate of soda as a mask. However, as we have stated, leaving bicarbonate of soda on alone or in a water solution can be damaging to the skin. This is why you will need to add one or more other ingredients to soften its impact while still making it effective as a skin lightener.
