The ISOI ACNI Dr. 1st Control Toner is a plant-based toner formulated for oily and sensitive skin types. It contains a blend of botanical extracts intended to help soothe irritation and reduce excess sebum production. The formula is designed to provide a cooling effect upon application, offering a refreshing sensation without stripping the skin’s natural moisture barrier. This toner aims to balance sebum levels while delivering light hydration, making it suitable for daily use as part of a skincare routine for acne-prone or combination skin. Key ingredients commonly featured in this product include plant-derived components such as tea tree leaf extract, centella asiatica, and salicylic acid, which are known for their calming and clarifying properties. The product is free from harsh chemicals and artificial fragrances, contributing to a gentle approach to acne management. With a volume of 4.39 fl oz (130 ml), the toner is designed to last through regular application. It is manufactured in South Korea and follows Korean skincare principles that emphasize hydration and skin barrier support. Suitable for individuals seeking a non-drying toner that helps control shine throughout the day without causing tightness or irritation. This toner can be applied after cleansing, using a cotton pad or hands, to prepare the skin for subsequent steps. The cooling effect may be more noticeable during warmer weather or after physical activity. The product is intended for external use only and should be avoided if any known allergies exist to its components. As with any skincare product, patch testing is recommended before full-face application. The packaging is functional and designed to preserve the integrity of the formula. The toner is not a treatment for medical conditions and is best used as part of a comprehensive skincare regimen tailored to individual needs.
