VT Cosmetics Reedle Shot 100 is a daily, "Step Zero" skin booster designed to enhance absorption of skincare ingredients through mineral-derived "cica reedles" (microneedles). It accelerates cell turnover and treats skin texture, pores, and tone, featuring Centella Asiatica to calm skin. The serum creates a tingling, microneedling sensation while aiding in hydration and brightening, commonly used for achieving "glass skin".
