Marissa Scalish. Advisor: Dr. Katy Lustofin. Introduction. Accutane, also known as 13-cis-retinoic acid, is a very effective acne medicine that has been on the market for over 24 years (Goodheart, 2006, 9). Retinoic acid is derived from Vitamin A, which is why this drug is considered a retinoid (Makori et al., 1998, 210-211). Vitamin A is known to be a vital component of embryonic development, tissue differentiation, and epithelial cell growth (Garcia-Fernadenz et al., 2005, 36). If Vitamin A concentrations become too high or too low, developmental defects can arise (Huang et al., 2005, 202).. Development of the oral cavity.
