Upon interaction with GSH, IR806-PDA is converted into IR806-S-NH, resulting in a spectral shift (from 680 to 820 nm) and generating ratiometric photoacoustic signals that correlate with GSH levels
Because the molecule is delicate and subject to chemical and physical degradation (peptide bond hydrolysis, oxidation, aggregation, microbial contamination), how it is stored and how long it remains effective (its shelf life) become critical for anyone handling it
Better circulation and deep hydration work together to minimize that hollow, exhausted appearance that even concealer can't fully hide
