Baths are better than showers for keeping moisture on the skin. If you take showers, put moisturizer on afterwards. A good quality moisturizer like Aveeno is much better than just any inexpensive one. You will notice a difference.
As well, make sure you're drinking a lot of water as this will help with dryness, wrinkles, and a ton of other stuff. If you shave or wax your legs try to moisturize before and after. Having moisturized skin will make the hair removal more comfortable and it will feel less dry and painful afterwards.
