Refined carbs, like white rice, and foods with a high sugar content like fizzy drinks, cakes and biscuits, can affect your skin and overall health.
Don't cut out carbs altogether as you need them in your diet, but it's better going for brown/wholemeal /wholegrain over white as the former has more nutrition; that's for rice, pasta, bread etc. And there's nothing wrong with the occasional treat if you eat healthily most of the time!
