How Lactic Acid Benefits the Skin

- Smoothing: Lactic acid smooths the skin's surface, improving texture.
- Evening Skin Tone: It helps to even out skin tone by reducing the appearance of dark spots.

- Reduction of Fine Lines and Wrinkles: Lactic acid may reduce the visibility of fine lines and wrinkles.
These benefits make it a popular ingredient in many skincare products.
