Question

Can Galactomyces Ferment Filtrate (Pitera) be applied directly to the face at a 100% concentration? If used undiluted, what potential effects or side effects (such as texture issues) might occur on the skin?

Answer

Yes, Galactomyces Ferment Filtrate (Pitera) can be used directly on the face at a 100% concentration.

According to the product specifications for both the standard and the glycol-free versions of Galactomyces Ferment Filtrate, the recommended usage rate is 1-100%.

What happens if you use it undiluted (100%)?

  1. Potential Greasy/Oily Feeling: The product description notes that using it in high doses (including 100%) "Might feel a bit greasy / greasy" on the skin, depending on the individual's skin type and the specific batch/concentration of the extract.
  2. Safety: It is generally considered safe for direct application at high concentrations. Many commercial "ferment essence" products contain Galactomyces Ferment Filtrate at concentrations exceeding 90%.
  3. Product Composition: It is important to note that the raw material sold as "Galactomyces Ferment Filtrate" is typically stabilized. For example, the Glycol-Free version (Product ID 35561) is 99% Galactomyces Ferment Filtrate with 1% stabilizers/preservatives (Hydroxyacetophenone and 1,2-hexanediol). The standard version (Product ID 357) contains Butylene Glycol, which acts as a preservative.

Recommendation:

  • If you choose to use it at 100%, monitor your skin for any signs of irritation or discomfort.
  • If you find the 100% concentration too heavy or greasy, you can easily dilute it with distilled water or mix it into a simple base formulation.
