I recommend a lip product I bought with my own money.

This is a MAC Sheer lipstick that I bought with my own money.
It makes a great gift, so I've given it to many of my acquaintances for their birthdays.
It seems to suit cool tones better than warm tones.
However, it suits warm tones well too!!
It applies well and is moisturizing, so even if you don't use a separate lip balm, it doesn't dry out and the color comes out well.
If you haven't found your perfect lip product yet, I recommend MAC Sheer!
