How should you patch test a new beauty product?
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.
