I've been using PawPaw ointment on my lips for about three years and I'll likely do so for a looong time!
The tiniest amount goes a LONG way and leaves your lips feeling hydrated and moisturized for hours. The product absorbs very quickly and you aren't left with a sticky residue, whilst also being much longer lasting than other products (in my experience, e.g. chapstick). I personally quite like the lack of scent and its transparency, hence it also works well as a base when applying lipstick.
Value for money is great, with the smallest tube lasting at least 6 months. Varying tube sizes mean that if you're like me and use this product all the time, you can have multiple tubes on the go to suit your activity.
