For adults, acetic acid (a form of vinegar) is usually safe in the small amounts used in skincare. The biggest problems are irritation or burns if the product is too strong or used on broken skin.
Use products that list acetic acid at low concentration and follow the product label. Patch-test a small area of skin first if you have sensitive skin. Do not apply to cuts, open wounds, or the area around the eyes. Avoid products that smell very strong or that list concentrated or 'glacial' acetic acid. If you get strong burning, redness, or breathing difficulty, rinse and seek medical help.
Some government agencies note risks from higher or repeated exposures (Environment Canada) and strong concentrations carry workplace hazard labels (EU GHS). The ingredient is allowed at limited levels in food (FDA). Also, some product-certification programs restrict its use unless the manufacturer provides safety information. For adults, the main things to watch for are skin irritation, eye contact, and strong fumes from concentrated forms.
