Preventing Oxidation and Moisture Contamination Minimize Air Exposure: Limit the time peptide containers are open to reduce oxidation, especially for peptides containing cysteine (C), methionine (M), or tryptophan (W), which are prone to air oxidation
Important chemical contaminants reported to cause neurotoxic effects in humans at environmentally relevant levels of exposure include polychlorinated biphenyls (Schantz et al., 2003), arsenic (Wasserman et al., 2004), lead (Lanphear et al., 2005), manganese (Takser et al., 2003), pesticides (Rauh et al., 2006), polycyclic aromatic hydrocarbons (Perera et al., 2006) and mercury compounds (Grandjean et al., 1997
South Korea is similarly investing in skin-brightening formulations and wellness supplements, reflecting its strong cosmetics and K-beauty industries
