Ingredients and actives
Azelaic acid
Also written as azelaic suspension.
Often formulated as a thick, slightly grainy suspension rather than a clear serum. It settles.
What it needs from a bottle
Suspensions need a container the customer can shake and a closure that will not weep. A dropper on a grainy suspension blocks. Use a tube or a tottle and let them squeeze.
Formats that suit it
- Tottles
- Tubes
Order from a single bottle, so a first run can be a test rather than a bet on a guess.
