My advice would be to start slowly so that you avoid irritation, redness and over drying your skin. Don't go for the full amount right away. Begin with a small amount of bp at bedtime only and see how it goes for a couple of weeks. Increase the amount or apply bp in the morning too if your skin is tolerating it well.
It can take a while to see results so don't get discouraged.
Have you tried any diet changes such as cutting out dairy, processed foods and sugary treats?
Try and get enough sleep and don't get too stressed out (probs hard to do with a wedding coming up!)
