Serum Manufacturing: Formulation & Packaging

Short answerIn a serum, formulation and packaging cannot be considered separately: the product’s goal and texture affect which packaging suits, and packaging affects how the formulation is used. Write goal, texture and way of use together in the brief; stability and testing expectations should be clarified per project.

Define the product goal

A serum usually focuses on a specific care approach. When the goal is clear, formulation options are easier to evaluate. It is more accurate to describe the goal through user experience and care approach than through unmeasurable effect claims.

Texture and way of use

A serum’s texture can be watery or gel-like. Texture determines the dosing method of the packaging (dropper, pump, ampoule).

How does packaging affect it?

Dropper bottle: controlled dosing, premium perception
Pump bottle: practical use, depends on fluidity
Ampoule: single-use format

Each option has different production and filling requirements, so packaging should be discussed early.

Stability and testing expectations

Expectations about how the product behaves over time and its testing scope should be discussed at the start of the project. This article claims no stability result or test output; scope is set separately for each project.

What to add to the brief

Target approach, texture, way of use, packaging preference and estimated quantity are the core of the brief. For more, see our contract serum manufacturing page.
