If you’ve heard it once, you’ve heard it a thousand times: Drinking water helps your skin stay young looking. In fact, it’s a myth. Water is good for your overall health and the skin of someone who is severely dehydrated will benefit from fluids. But the average person’s skin does not reflect the amount of water being drunk. I see clients who drink their 10 to 12 glasses of water a day and still have super dry skin. It just doesn’t do that much.
