I really like Vaseline Lip Therapy Rosy Lips Lip Balm Tin - it moisturises the lips nicely and provides a small tint of colour. It's lightly scented rose and you know you'll be using this product for years as it takes so long to get through.
You can also easily find this product in stores for a cheap price, so it's always a great option to keep in your makeup kit or bag for on the go. I use this at night time as I prefer more hydrating/ SPF lip balms for the day, but as this is so occlusive, it makes a great mask for night time.
