What Beauty Product Gets Better the Longer You Own It?

Requirements:

must have used for 6+ months

explain long-term benefits

Extra Details:

What beauty product became more valuable over time instead of less? Most beauty purchases are exciting for the first few weeks. Then they end up forgotten in a drawer, replaced by the next trend. I'm looking for the opposite: products that revealed their value slowly. Maybe it took months to see the results. Maybe you learned new ways to use it. Maybe it saved money because you stopped buying alternatives. Or maybe it's one of those rare purchases that quietly became part of your daily routine for years. Not necessarily the most expensive product. Not necessarily the trendiest. Just something that genuinely improved your life the longer you owned it.
