Understanding glycerin.
A moisture-binding ingredient in the water-based serum base.
01
What is glycerin?
Glycerin, also called glycerol, is used in cosmetic formulations as a moisture-binding ingredient.
Why this ingredient?
Its role in the skincare base is to bind moisture. The selected study examines measured hydration of the stratum corneum.
02
What the research examines.
A double-blind human study examined a cream with 20% glycerin over ten days.
03
Putting evidence into context.
The cream studied and its concentration differ from NOCTE. Skin hydration, water loss and irritation responses are different outcome measures.
04 / NOCTE
The role in NOCTE.
Glycerin is one of the moisture-binding ingredients in the NOCTE serum base.

- What was observed?
- Measured hydration of the stratum corneum increased.
- Context
- No demonstrated effect on transepidermal water loss or sensitivity to SLS. This does not establish a general barrier-repair effect.
