mixsoon's Premium Galactomyces Serum uses Galactomyces ferment filtrate as the primary active, same ingredient class as SK-II's Pitera. At 98% galactomyces concentration (per the brand), this is one of the most concentrated galactomyces-hero serums in Korean skincare, and at a price dramatically below SK-II territory.
Galactomyces ferment is a yeast-derived complex rich in amino acids, vitamins, and minerals. Decades of research (primarily Japanese) support its benefits for skin smoothness, pore refinement, and overall skin quality. For users who want the SK-II Pitera experience without the luxury price tag, mixsoon's concentration and positioning make this a credible alternative.
Galactomyces ferment filtrate delivers amino acids, minerals, and fermented metabolites that support skin smoothness and tone evenness. High concentration accelerates visible results. Skin texture, pore appearance, and overall tone improve gradually over 4 to 8 weeks of daily use.
After cleansing and toner, dispense into palms and press into face and neck. Can be used as essence (before serums) or as primary treatment. Use AM and PM.
Pitera is SK-II's branded name for their specific galactomyces filtrate. Both are galactomyces ferments. Formulation varies; mixsoon's is comparable in ingredient, different in brand story.
Rarely. Fermented ingredients are typically well-tolerated.
For general skin quality, largely yes. For specific concerns (acne, anti-aging, brightening), supplement with targeted actives.
