Test a small area as directed, repeat before wider use, and stop for persistent burning, swelling, blistering, or worsening irritation.

## A careful way to test this

Keep the rest of the routine stable, follow current labels, and change one variable at a time. Stop if discomfort is persistent or severe.

## What the label can tell you

Check ingredients, directions, warnings, and intended use. Formula and claims can change, so the current package is the source of truth.
