Tretinoin is the acid form of vitamin A and is also known as all-trans retinoic acid. There are a variety of formulations in which tretinoin can be delivered. These vary in concentration and are available as a cream or gel (brand names Aberela, Airol, Renova, Atralin, Retin-A, Avita, Refissa, or Stieva-A). It is also available as a generic. There is no evidence to suggest brand names are superior, or different to, generic forms of tretinoin.
