Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.

Viscosity Controlling
Controls excess oil
Minimizes pores
Traditional Use
SD (Specially Denatured) alcohol was developed in the early 20th century as a taxed alcohol substitute for industrial and cosmetic use. This denaturant classification system was established by U.S. regulations to allow alcohol use in cosmetics while avoiding beverage taxation.
