Formulation Questions: Serum/Essence with Galactomyces, Kinetin, B3, N-Acetyl Glucosamine - Compatibility, Preservation, and Texture

Question

I have a formulation with the following ingredients:

I have a few questions regarding this formula:

Are these ingredients compatible and will they remain effective when mixed together?
Since the formula uses 80% Galactomyces Ferment Filtrate (which contains a preservative), is it necessary to add an additional preservative?
If I omit the Satin Cream Maker, will the formula become a liquid? Will the resulting texture be similar to SK-II essence?

Formulation Questions Answered

Here are the answers to your questions regarding the formulation:

Compatibility and Effectiveness: Yes, the ingredients in this formula are compatible and should maintain their effectiveness when mixed together as described. The combination of Galactomyces Ferment Filtrate, Kinetin, Vitamin B3 (Niacinamide), and n-acetyl glucosamine is suitable for addressing concerns like wrinkles, skin tone, and hydration.
Need for Preservative: Based on the high concentration (80%) of Galactomyces Ferment Filtrate (Pitera) used in the formula, an additional preservative is not necessary. The Galactomyces Ferment Filtrate product itself contains a preservative from the manufacturer, which is sufficient to preserve this formulation.
Making a Liquid Formula without Satin Mousse: If you omit the Satin Cream Maker, the formula will result in a liquid texture. However, the texture will not be exactly like SK-II essence because your formula includes Kinetin, Vitamin B3, and n-acetyl glucosamine in addition to the Galactomyces Ferment Filtrate. To achieve a texture most similar to SK-II, you would need to use primarily or only the Galactomyces Ferment Filtrate ingredient.
