That kind of claim is almost always clickbait, not science.
There’s no evidence that drinking or applying vinegar can make someone “look 30 years younger” or reverse aging in any meaningful way. Apple cider vinegar, for example, is sometimes promoted online for skin or weight loss, but research doesn’t support dramatic effects like transforming a 60-year-old into looking decades younger.
What does affect how someone ages visually is a mix of:
- genetics
- sun exposure (UV damage is a big one)
- smoking/alcohol
- sleep and stress
- skincare habits (like sunscreen and moisturizers)
Vinegar can be useful in limited, practical ways—like in food, or as a mild cleaning/antifungal agent—but using it on skin or drinking large amounts can actually cause irritation or harm (like acid damage to teeth or stomach upset).
If you want, I can break down what actually works for keeping skin looking younger in a realistic, evidence-based way.
