Does a cosmetic label claim prove the product works?
No. A claim on the front of the package is not the evidence. Read the ingredient list, directions, warnings, and the specific support for the claim.
Keep the test simple
Change one thing at a time, follow the current label, and note timing and symptoms. That makes benefit or irritation easier to identify.
When should you stop?
Stop for persistent burning, swelling, blistering, hives, or worsening symptoms. Seek urgent help for breathing trouble or severe swelling.
