Drinking water, however, is not the cure-all for pimples. Hydrating helps your skin self-moisturize and cleanses your cells of built-up waste, but It does not directly affect your oil production. For many, over-production of oil is the main cause of their acne. To combat excess oil, treatment is necessary.
How long does waxing last? It varies for different people depending on their natural hair growth. After the first wax treatment most people will have re-growth after 3 weeks. This period will extend up to 8 week with consecutive treatments. Some people will find they can go for more than 2 months in between treatments.
The sad truth about waxing is that it may happen as long as a month before the mare foals, although up to two weeks is more common. Either way, it's not a very reliable sign! The best indicator I have found yet consists of the inspection of a few drops of the mare's milk once a day.
