I'm curious about the effects of Botox. Has anyone tried it?

Whenever I meet friends or browse social media, I hear a lot of talk about Botox. To be honest, since I am just in my early 20s, I don't have deep wrinkles or signs of aging yet, but I’ve recently been feeling a strong desire to take a step further and cultivate clear and smooth skin. In particular, concerns about skin texture—such as enlarged pores that bother me subtly every time I apply makeup, or the fine unevenness visible under the lights—are actually quite stressful for me.

People around me say that getting skin Botox, which is injected thinly into the dermis, makes the skin glow and refines the texture. Is the effect really good enough for someone like me in my early 20s to actually notice? What I want most is to look naturally beautiful, as if my skin is naturally good, rather than looking artificial and obviously surgically altered.

However, on the other hand, I am also worried. I am concerned that if I start Botox treatments at such an early age, my skin might sag further when the effects wear off, or that I might have to keep getting treatments periodically for the rest of my life to maintain the results. Has anyone around my age received these treatments to improve skin texture or reduce pore size?

I'm curious about how long the effects typically last after the procedure, and whether the skin really feels firmer and clearer! I'm hesitating because I'm a bit scared, so it would be a huge help in making a decision if you could honestly share information about the pain or potential side effects to watch out for. I'm deeply concerned because I want to maintain the vibrant skin of my 20s for as long as possible. I would appreciate your advice!
