What do you need to do/know about needling around the eyes? (esp ST 1) 1. Need good communication with your patient – they need to know what you’re going to do, what the risks are, what to expect. Bruising is a real possibility. 2. CNT techniques should be strictly applied. High risk of infection. 3. Select short, thin needles. 4.
