Known Interactions
DHA undergoes Maillard browning with free amino acids on skin to produce melanoidins (the tan). Free amino acids IN THE FORMULA (aloe vera juice, hydrolyzed proteins, peptide complexes, amino acid blends) react with DHA pre-application, degrading the active and accelerating off-smell development over shelf life. Remove the amino-acid source, switch to glycerin/propanediol/sodium PCA for hydration, or use encapsulated DHA if the amino-acid ingredient is brand-critical.
