medicube Deep Vita A Retinol Serum 30ml 2-Pack

Features

medicube Deep Vita A Retinol Serum 30ml 2-Pack is a 4th-generation retinol serum designed to provide intensive elasticity lifting and address major skin concerns. Developed by medicube after extensive research including 3 years of ingredient research, 150 days of upgrade tests, and 60 days of stability tests, the serum utilizes a 3-stage stabilization method that encapsulates retinol in liposomes to protect the active ingredients and absorb them deeply into the skin. The formula features a watery texture that absorbs quickly into the skin without stickiness, allowing high efficacy even with a small amount.

Benefits

The serum delivers total anti-aging care by targeting major wrinkles, sagging skin lifting, enlarged pore elasticity, freckles, blemishes, and skin texture. It provides dual functionality for brightening and wrinkle improvement certified by the Ministry of Food and Drug Safety. Clinical and consumer testing demonstrates significant improvements, including 11.9% improvement in skin age after 4 weeks of use, based on evaluations by the P&K Skin Clinical Research Center with 24 subjects from December 13, 2023, to January 12, 2024. Additionally, 96% of 294 Hwahae users reported overall product satisfaction.

Clinical test results

Human application tests conducted by Global Medical Research Center from August 29 to September 26, 2023, with 32 subjects demonstrated zero skin irritation responses (0% skin reaction rate). Further clinical testing proved effectiveness across 25 human application tests, showing improvements such as 25.5% in forehead wrinkles, 16.5% in crow's feet, 75.0% in skin depression marks, 16.9% in neck wrinkles, 14.3% in wrinkle area, 11.9% in frown lines, 11.2% in nasolabial folds, 7.5% in skin density, 5.7% in under-eye puffiness (eyebags), and 3.2% in facial lifting.

Usage instructions

For the initial 2 weeks, use the serum every other night after evening cleansing by applying a moderate amount (about the size of a grain of rice per area) to concern areas such around the eyes, mouth, frown lines, and neck. After the initial 2-week adaptation period, gradually increase usage frequency to every night and apply a thin layer across the entire face. If used in the morning, ensure thorough application of sunscreen afterward as retinol can be sensitive to light and heat.
