If you have dry skin or red skin you likely have a skin barrier malfunction. This can come from over exfoliation, lack of moisture (internally) or using product that isn't best for you. I find that most people are using too many things which complicates figuring out what is best to continue or stop.
Food plays a part here as well. A low fat diet may be great for your waist line but it can sometimes really be tough on your skin and moisture balance.
Add in some:
* fatty fish like salmon
* avocados contain good fats that nourish skin
* sunflower seeds
* dark chocolate
As I mentioned, I am not a doctor. If you have dietary restrictions or health conditions please discuss nutritional changes with your doctor. Eating a diet rich in good fats is proven to improve skin. Be good to yourself, eat good foot, get facials, and wear some SPF. You got this!
