Furthermore, it is said to decrease polyamine synthesis and keratinisation, which contributes to its anti-inflammatory and anti-prolific properties.3 The UK licence for isotretinoin was first established in 2001 with strict pregnancy prevention criteria and regular monitoring of blood tests, namely liver function tests and lipids.4 Whilst widely used in acne, there are a number of other dermatological…
