Peptides are oxidation-sensitive but not acutely so; the bigger risk in practice is adsorption onto the pack surface, which is a function of contact time and surface area rather than of air. Airless cuts contact time per dose and is the conservative choice, with glass as the standard alternative.
Peptide Serum is one of 1,665 formulas in the library that fall into this form. Across the whole library, 52% of them are built for a glass bottles — that is the format the form itself is designed around, not a preference we hold. If the formula you pick is lighter or heavier than the typical peptide serum, the recommendation moves with the viscosity, which is why every formula page in the library shows its own pack pairing rather than a category rule.
Typical textures in this group: Watery gel-serum, Light milky serum, Slippery essence, Silky fast-absorbing serum.













Avoid a large headspace and avoid long, thin dip tubes on a low-dose peptide — the product that sits in the tube between uses is the product that never gets used.
