How to make myself look younger while still young?
I need some serious advice on this matter. I'm only 20 and yet I look 35 or 40. (yikes) My facial hair grows back quickly so my lack of trimming usually makes me look older in that area. But somehow I feel like this isn't enough. On top of that, I've eaten junk food a lot when I was younger, rarely drank any water and I've stayed up late a whole lot and gained a whole lot of weight. Moreover, I've stressed myself out with schoolwork on a daily basis during high school.
Recently, I've lost 30 lbs and I'm now down to 150 lbs. But I still look 35. Is this damage irreversible or can I change it while I'm still young. If yes, what should I do and how long should I expect to look the age that I actually am?
Good news is that I've never drank, smoked or done any drugs to make things worse.
I look forward to answers. (possibly a good one that says that it isn't too late) Be honest, is there any hope or am I doomed?
