Ingredients and actives
Hyaluronic acid
Also written as HA serum, sodium hyaluronate.
A humectant sold at a range of molecular weights. In a serum it is usually thin and slightly tacky.
What it needs from a bottle
Tackiness is what to design around. A sticky serum drags on a dropper bulb and gums the thread over time, so a treatment pump ages better than a pipette on anything above a light gel.
Formats that suit it
- Treatment pump bottles
- 30ml droppers
Order from a single bottle, so a first run can be a test rather than a bet on a guess.
