Is Korean skincare worth it?

Before I discovered Korean skincare, I was into the western drugstore brands that are available in the market like Pond’s, Nivea, Olay, and St. Ives. Looking back, I did enjoy these brands and their products especially so that they are the only ones that I can afford at that time. But with efficacy wise, I didn’t get the skin I wanted to have perhaps because I did not discover sunscreen yet or the formulations are not as innovative as with Korean skincare.
