I really like Himalaya skin care products.
The lip balm lips tend to ger frequently chapped, dry and flaky during winters.
As a natural remedy, simply apply same ghee on them before retiring go bed.
You can also scrub your lips using petroleum jelly and a soft toothbrush or a honey and brown sugar scrub.
If you are using commercially available lip balms, do look out for spf too.
as they are natural
Not very expensive
