🙋‍♀️⁉️ Daiso vs. Estée Lauder—there's a 50x difference, so expensive cosmetics aren't necessarily better, right?

This is the Bonsept BTC Freeze Ampoule that was a hit at Daiso this summer.
This was also very popular, so it was hard to find for a while.
I tried it too, and the whitening effect was so good that I stocked up on it.
These days, Daiso is releasing a lot of cost-effective cosmetics, and there are many popular products.

Estée Lauder's brown bottle is so famous that I used it in the past, but honestly, I didn't feel like it had much of an effect.

There is more than a five-fold price difference between Daiso products and Estée Lauder products, so expensive cosmetics aren't necessarily better, right?

Actually, the cheaper products seemed to suit my skin better.
