What are common beauty hoaxes that are a waste of money?

1. Expensive creams are better than cheap ones. The primary purpose of a cream is to moisturize and prevent water from evaporating from your skin. It doesn't matter whether you use a $5 cream or a $100 one, as long as your skin is not dry after you apply a cream. Active ingredients in creams don’t matter much because there’s little chance your skin absorbs them effectively. Buying expensive creams like La Mer is a waste of money—you’re just burning through your cash.

2. Supplementing collagen for better skin. Collagen is broken down into amino acids during digestion, just like any other protein. It makes no difference whether you consume collagen supplements or eat protein-rich foods—they’ll both be digested into amino acids

3. Using toner to balance skin pH. Toners are often marketed as necessary for balancing skin pH, but in reality, your skin’s natural barrier is capable of regulating its pH without additional products.

4. Doing manicures. Manicures can be expensive, non-aesthetic, and a waste of money. Natural nails often look better and are easier to maintain.

5. Getting lash extensions. Lash extensions are costly, time-consuming, and only last about a month. The upkeep is often not worth the expense or effort.

6. Permanent laser hair removal. hair often regrows after laser treatments. It’s not truly permanent and can require additional sessions
