Which cosmetic preparations cause the contraction of skin tissues?

Astringents are cosmetic preparations specifically designed to cause the contraction of skin tissues. They contain specific ingredients that have a tightening effect on the skin, which helps to reduce the appearance of pores and oiliness. Astringents often include alcohol or other chemical agents that may have a drying effect, making them useful for oily or acne-prone skin types that require extra oil control and pore tightening.

In cosmetic and skincare contexts, moisturizers are formulated to hydrate and soften the skin rather than contract it. Fresheners and facial toners serve different purposes; they may help to cleanse and balance the skin's pH or provide hydration without the significant tightening effect associated with astringents. Therefore, astringents are the most appropriate choice for skin contraction among the options presented.
