Can baking soda lighten acne scars?

There is no reliable evidence that it safely fades acne scars or post-inflammatory hyperpigmentation.

Why does my skin feel smoother after using it?

Baking soda can remove surface oils and dead skin cells, creating a temporary smooth feeling. However, overuse may damage the skin barrier and lead to irritation.

Is it safe to use every day?

No. Daily use is not recommended because it can dry out and irritate the skin.

Final Thoughts

While baking soda is excellent for baking and many household cleaning tasks, it is not an evidence-based anti-aging or skin-lightening treatment. If your goal is healthier, more even-toned skin, a consistent routine that includes gentle cleansing, moisturizing, daily sunscreen, and proven ingredients like vitamin C, niacinamide, or retinoids is a safer and more effective long-term approach. If you have persistent acne, dark spots, or signs of premature aging, a dermatologist can recommend treatments tailored to your skin type.
