Diet has an important role to play in many skin disorders.
In general, there is a lot of talk about diet, hygiene and sunlight exposure, and how this relates to acne. Surprisingly little well studied evidence exists. This means that we, as doctors, can’t be firm about telling our patients exactly what to do about acne when it comes to diet, face-washing, and sunlight.
The best thing is to give individualized advice.
-From a practical point of view, it is useful to keep a diet journal, and so *you* can decide how this affects your skin.
-Use sunscreen! We know sun causes damage.
-Face-washing may help, and there are products that can be applied to skin that will assist with mild acne
