Worst looksmaxxing advice you've seen

For the entertainment and education of the community: what's the worst looksmaxxing advice you've encountered? I'll start: facial exercises to change bone structure. Not mewing — I mean the specific exercises marketed by people selling courses, things like chewing in weird ways, using face rollers 100 times a day, doing facial yoga. The muscles of facial expression don't pull on bone in a way that causes meaningful remodelling. Spent three months doing a course before realising this.

The lemon juice as a natural toner trend. Lemon juice is strongly acidic, photoactive, and causes phototoxic reactions and hyperpigmentation — the exact opposite of what people are trying to fix. Saw someone recommend it as a "natural vitamin C serum." Please use actual skincare products.

The "natural DHT blockers will regrow your hair" supplements. Saw biotin, zinc, saw palmetto, and pumpkin seed oil being recommended as fin alternatives. Some of these have weak evidence for modest effects. None of them comes anywhere close to finasteride's mechanism or efficacy. People spend a year on supplement stacks losing hair that fin would have preserved.

"Mewing will restructure your jaw in 30 days" content on social media. Mewing, if it does anything structural, works over years of consistent practice. The 30-day before/afters are either lighting tricks, camera angle changes, or people losing weight. Setting unrealistic timelines makes people quit before any real benefits could accrue.

Extremely low calorie dieting to "get a lean face" faster. Severe caloric restriction causes muscle loss, makes you look gaunt and unhealthy, and usually results in rebound weight gain with more fat and less muscle than before. A moderate deficit of 300-500 calories preserves muscle, loses fat steadily, and actually produces a better result over 6 months than starving yourself for 6 weeks.

Any advice to do something irreversible (surgery, permanent fillers, tattoos) without extensive research and waiting periods. The number of people I've seen in before/after posts with filler placed poorly or surgery results they regret because they rushed the decision — it's significant. There should always be a minimum 1-year consideration period for anything irreversible.
