Speaking of feel - silk pillow cases have a reputation for luxury, but listener Cathy wants to know whether sleeping on one will - as the marketing promises - also help your skin and your hair. Could it really help with acne? We'll hear from a dermatologist and a fabrics expert - and there are some surprising answers to this one!
