If you have ever wondered what makes SK-II Pitera Essence so expensive, the ingredient list gives a surprisingly short answer. There are only seven ingredients. Here is what each one does and which skin it suits.
Related ingredient guides: Galactomyces
The first ingredient is not water but galactomyces ferment filtrate, which SK-II calls Pitera. Butylene glycol and pentylene glycol come next, and water only appears after them. In other words, there is more ferment filtrate than water.
The other three are sodium benzoate, methylparaben and sorbic acid. All three keep the product from spoiling. There are no oils and no thickeners, so it goes on as light as water.
Galactomyces is a type of yeast. The filtrate is the liquid strained off after the yeast is grown, and it is used to keep skin moist and smooth its texture. It is also known as the ingredient that started the Korean fermented essence trend.
Keep expectations accurate, though. There is little research on its effects as a topical skincare ingredient, and it is not an MFDS functional ingredient for brightening or wrinkles. Think of it as a hydrating essence that leaves skin moist and smooth.
The butylene glycol and pentylene glycol help by holding water. Pentylene glycol also helps keep the product from spoiling.
There is no fragrance, silicone or mineral oil. Methylparaben is used as a preservative instead. It is used within set limits and is fine for most people, but if you avoid parabens, it is good to know before you buy.
It is a watery formula with no oil at all, so it suits oily skin and routines with many layers. With no fragrance, scent-sensitive skin can try it too.
Dry skin will need more than this alone, so always follow with a cream. If fermented ingredients have caused breakouts before, patch test behind the ear first.
