My skin looks dull and I want to make it glow. What should I do?

There are various treatments and home care methods being introduced, but I'm curious about which method is most effective for maintaining radiant skin. For example, I'd like to know whether treatments like laser treatments or skin boosters can help achieve radiant skin, or whether consistent lifestyle habits are more important. I'm also confused about what criteria should I use to select cosmetics and supplements for radiant skin. If anyone has experience with this, it would be helpful if you could share what methods you tried and how satisfied you were with them. I'm still trying to decide which method to choose, so I'd love to hear your opinions.
