But with aging, or with environmental stress conditions, the level of glutathione can be easily depleted leading to dull complexion and worthless skin tone
Specifically, the substitutions at the 2nd, 15th, and 27th positions may help the peptide resist being broken down by enzymes and extend its half-life
