Dyshidrotic eczema

I am fortunate not to suffer from allergies or dyshidrotic eczema, but I do get dry skin patches from time to time. I have not figured out what causes the patches, but as they are not too noticeable, I have not sought any treatment as such.
Occasionally I use a cream, and I avoid after-shave completely, preferring to use a moisturiser rather than a traditional after-shave.
Two major contributors to skin problems (apart from environment) are stress levels and the types of food that we eat - it's remarkable how our lifestyles affect our health without us truly appreciating the impact.
