Context to my question: I have always been dry, even dentists comment. I've always had a lot of water, nothing else quenches my thirst. A few years ago I hit a new bracket, peri dried me up further and had to source new products for skin and hair and I'm constantly researching new products. I recently started using The Ordinary (I know this has been talked about a lot on here but I've only just started using it myself!) and in reading about their products I finally read Caroline Hirron stuff. She said that make up that disappears from the face during the day tends to be a side effect from dehydrated skin and that the skin is taking in the water from the makeup - hence the disappearing.
So, I just googled how much water I should drink and found a site that recommended an ounce for every pound you weigh. I easily drink 2 litres, probably more, but I don't measure it. According to this site I should be drinking 4 to 5. I'm going to measure my intake today.
Has anyone had dehydrated skin and drunk the ounce per pound and found this helped their makeup last?
