When I was younger lotion was optional. I don't recall ever having dry, itchy, ashy skin when I was or kid or even in high school. I first discovered that there wee benefits to lotion in my college years and by my forties it was an absolute necessity. Period.
So why does our skin tend to become drier as we grow-up? Dermatologists say that we have fewer natural oils as we age. Combined with the impact of sun exposure over time, a reduced rate of cell renewal, and not drinking enough water can lead us to have drier, rougher skin.
The key to good skin is to combat the controllable things to keep your skin soft and supple both inside and out. Drink your water and slather on lots of Global Girl Shea Butters which offer nutritional value and protection.
