Some dryness and "flaking" are normal with every effective acne treatment. These symptoms are expected to calm down in 2-3 weeks, once your skin gets used to the products. 

To reduce this skin dryness, you can combine a small quantity of the night cream (pea size) with an equal amount of the moisturizer in your palm. Mixing the two creams will result in a diluted, milder treatment cream, which you should apply to the whole area with acne (not just individual pimples). 

Do not apply your treatment cream to the sensitive areas on the neck, around the eyes, around your mouth, or the edges of your nose as the skin in these areas is thin and very sensitive. 

Make sure you wash your hands after you apply the cream so that you don't accidentally spread the treatment to those areas afterward. 

Please track your skin and update us in 2 weeks. I needed would be able at that point to further fine-tune your medications and send you with your next kit a less drying night cream.
