Lyophilization, or freeze-drying, removes water from a frozen product under low pressure, leaving a dry powder. It is widely used for proteins and other delicate ingredients because dry forms tend to be more stable. Folli-Fuel's powder is freeze-dried and mixed just before use.
The process
The product is frozen, then water is removed as vapour without passing through liquid. Reviews of freeze-drying describe it as a way to protect sensitive proteins.
Why it matters
Mixing fresh in the centre means the ingredients are reconstituted only when your session starts. This is about stability, not proof of results.
Questions
Is freeze-dried better than liquid?
It is often more stable for delicate ingredients.
Can I see it being mixed?
Yes.
Studies mentioned
These studies looked at ingredients or general approaches. None of them tested our treatments or products, so they are background, not proof.

Freeze-drying is one of the main drying methods used to improve the storage stability of therapeutic proteins.PubMed 30126135doi:10.3390/pharmaceutics10030131

Proteins and peptides in liquid form often degrade during handling; solid formulations, including freeze-dried products, are used to maintain stability during storage and transport.PubMed 25565441doi:10.4155/tde.14.98
