Pore Tightening

Tannins are a kind of astringent, A polyphenolic structure that binds and precipitates proteins. Typically when we drink wine, the wine's bitterness and astringency taste are from tannin, cause they shrink the proteins in the mouth. ZYMOGEN focus on "Galla". That natural ingredient included plenty of natural tannins. The natural tannins from Galla shrink pores and make skin looks refined.
