Detailed answer

Baking soda does not have proven benefits for treating scars. While it may help with exfoliation and skin brightening, it lacks the necessary properties to effectively reduce the appearance of scars. Scars are formed due to permanent changes in the skin's structure and require specific treatments such as silicone sheets, topical creams with ingredients like retinoids or vitamin C, laser therapy, or surgical intervention. Consulting a dermatologist is recommended for proper scar treatment as they can provide a personalized approach based on the scar's type, location, and severity.
