Classification of Yeast-Derived Cosmetic Ingredients

Based on the information from the product descriptions, these four substances are related as they are all derived from yeast fermentation, but they are not all the exact same type of substance.

Here's a breakdown:

• Galactomyces Ferment Filtrate (Glycol Free, Glycerin Free, Preservative Free) and Galactomyces Ferment Filtrate (aka Pitera): These two are essentially the same core ingredient, Galactomyces Ferment Filtrate, often known by the trade name Pitera. The difference between the two specific products is in their formulation; one is free from glycol, glycerin, and preservatives, while the other (the "normal type") contains Butylene Glycol.
• Dermal Respiratory Factor: This ingredient is identified as Saccharomyces Lysate Extract. While also derived from Saccharomyces yeast, the description indicates it is produced by lysing (breaking open) the yeast cells and extracting the fluid. It is presented as having similar effects to Galactomyces Ferment Filtrate but is more concentrated, requiring a lower usage rate.
• MYFerment™ Balance (Saccharomyces Ferment Filtrate): This is Saccharomyces Ferment Filtrate, obtained by fermenting Saccharomyces cerevisiae yeast and filtering the resulting liquid to get beneficial metabolites.

In summary:

• The two Galactomyces Ferment Filtrate products are the same type of ferment filtrate, just different versions.
• Dermal Respiratory Factor is a Saccharomyces Lysate Extract, which is a related but distinct type of ingredient derived from yeast.
• MYFerment™ Balance is a Saccharomyces Ferment Filtrate, another related type of ferment filtrate.

So, while they share a common origin from yeast fermentation, they are processed differently and are considered distinct ingredients with potentially different characteristics and recommended usage rates.
