R Substrates conjugated with amino acids include: Benzoic acid (from toluene exposure, food preservatives, and gut bacterial metabolism of polyphenols), conjugated with glycine to form hippuric acid R Bile acids (conjugated with glycine or taurine for proper emulsification and excretion) R NSAIDs and other acyl group drugs Phenylacetic acid (from phenylalanine metabolism), conjugated with glutamine to form phenylacetylglutamine R Salicylic acid (aspirin metabolite), conjugated with glycine to form salicyluric acid R Glycine conjugation is the most common amino acid conjugation
When applied consistently: dark spots may fade hyperpigmented areas may lighten uneven tone may improve However, if irritation occurs: inflammation may increase rebound pigmentation may happen sensitivity may rise Topical ingredients require careful skin barrier management
