Lactic Acid is a type of AHA (alpha hydroxy acid). It helps skin in two ways. It removes dead skin and adds moisture.

Other acids can be harsh. Lactic Acid breaks bonds between dead skin cells. This lets them fall off naturally. Your skin looks fresh and smooth.

You don't need rough scrubs. Those can hurt your skin. Lactic Acid is gentler.

It also pulls water into your skin. This keeps skin soft. It's great for dry or sensitive skin.

Your body makes lactic acid. It happens when you exercise hard. Muscles make it then.

Skincare products use lactic acid too. They get it from milk or make it in labs. This keeps it pure and safe.

Lactic Acid is bigger than glycolic acid (another AHA). It goes into skin slower. This means less irritation.

That's why many people like it. It's good for sensitive skin. It's also good if you're new to AHAs.
