Terpenoids can act as antioxidants, antiaging (improving antioxidant enzymes such as catalase, superoxide dismutase, and glutathione peroxidase levels) [192], anti-inflammatory, skin-whitening (by inhibition of tyrosinase activity) [192], antibacterial (against gram-negative and gram-positive bacteria) [193], and anti-acne bioactive molecules (acting against Staphylococcus aureus, a gram-positive bacterium associated with acne vulgaris pathology) (Figure 6) [194,195]. This evidence concerns the gene CAT and acne.
