How to Package a Vitamin C Serum: A Practical Bottle Guide

Vitamin C is one of the most demanded — and most fragile — skincare actives. The wrong bottle turns a hero serum brown in weeks. This is how to package it so efficacy survives the shelf.

What this formula needs from its bottle

L-ascorbic acid is light- and oxygen-sensitive, so the bottle must limit both. Options that work: an amber or frosted PET/PETG bottle (blocks UV), an airless pump (minimises oxygen contact and waste), or a dropper for oils. Keep the size at 30–50 ml — large enough to be a real treatment, small enough to be used before oxidation. A 24/410 neck takes standard droppers and airless actuators.

Practical tips

  • Choose amber, frosted or opaque PET/PETG over clear to slow photo-oxidation.
  • Specify an airless pump for water-based serums; use a dropper for oil-based formulas.
  • Keep the fill at 30–50 ml so the product is finished while still active.
  • Store and ship away from direct light; consider an outer carton for retail.

Questions buyers ask us most

What is the best bottle for vitamin C serum?

An amber or frosted PET/PETG bottle of 30–50 ml with an airless pump or dropper; both cut light and oxygen exposure that degrade the active.

Should a serum bottle be opaque?

Opaque or amber is ideal for light-sensitive actives like vitamin C; clear bottles need an opaque secondary carton to compensate.
