According to the provided reference, you can use baking powder in the following way for skin whitening:
- Mix baking soda and lemon juice into a smooth paste.
- Wet your face and apply it on the blemishes.
- Massage it gently and leave it for 2 minutes.
- Wash it off with plain water and let it dry.
Important Considerations:
- Sensitivity: Be extremely cautious when using this method. Baking soda is alkaline and can disrupt your skin's natural pH balance. Lemon juice is acidic and can cause irritation, especially on sensitive skin.
- Patch Test: Always perform a patch test on a small, inconspicuous area of your skin before applying it to your entire face.
- Sun Sensitivity: Lemon juice can make your skin more sensitive to the sun. Apply sunscreen after using this treatment, and limit sun exposure.
- Frequency: Do not use this method too frequently, as it can lead to dryness, irritation, and even damage your skin. Once a week or less is recommended.
- Baking Soda vs. Baking Powder: The reference mentions "baking soda," not "baking powder." While they are similar, baking powder contains baking soda plus an acidifying agent and a drying agent. Using baking powder might be milder, but it's still crucial to proceed with caution.
- Alternatives: Consider safer and gentler skin-brightening alternatives like vitamin C serums, niacinamide, or alpha hydroxy acids (AHAs).
