What is SpecKare® RRT

SpecKare® RRT is an advanced retinol complex encapsulated with hydroxypropyl cyclodextrin for stabilized, slow-release delivery. This controlled release minimizes irritation while maximizing anti-aging benefits like wrinkle reduction, skin firming, and texture improvement. Additionally, it supports acne-prone skin by normalizing keratinization and reducing excess sebum, making it effective and gentle for a wide range of skin types.
