Jessica, 19, comes into the pharmacy to ask if you have something for the dry, itchy skin on the backs of her knees. She says it doesn't usually bother her but she's going on holiday in a few weeks and wants to be able to wear summer clothes without feeling self-conscious.

• What further questions would you ask Jessica?
• What would you recommend? 
• Are you confident that you can advise Jessica on how to use the product you have recommended?
• What self care tips would you offer?
• What follow-up might you offer Jessica and how would you advise her if the treatment does not work?
