@HolidayHattie how brilliant that you feel your new skincare journey is working!
Annoyingly, consistency is more important than the products in my experience. But I totally understand that feeling of not finding the time or energy every single evening/morning.
Elizabeth Arden do a lipbalm shaped like a lipstick in their 8 Hour range. Much easier to use than the actual cream. It is excellent.
A dab of coconut oil as when you remember really helps. It sinks in very quickly and you won’t be left with that oily residue. Keep a tiny jar by the kitchen sink and you’ll remember to use it.
Vaseline is useless on dry lips, I find it makes the problem worse.
Are you drinking enough water and consuming enough oils? Dryness on skin is often a reflection of what is going on the inside.
Are you using any face exfoliating product that spreads to lips and perhaps it is too harsh on lips (something with glycolic acid for example)?
