You do what's best for you. You do not need anyone's approval. But remember, whatever you do today, it will reflect on who you are in the future. Not just with lipstick,but any other makeup, it can lead to premature aging.
If you choose to wear lipstick anyways, I recommend the peach or beige. Not only it looks modern but also, light and natural. I suggest you rather use a lip balm rather than lipstick because lip balms protect your lips. Make sure you get one that has SPF 15.
Now, lipgloss, I am somewhat against. One day you will know what it symbolizes (I learned in High School), and it's too provocative.
But, good luck!
Just don't make it a top priority in your list.
Natural beauty is the best thing!
