Clinical test results

Tested by the Korea Institute of Dermatological Sciences from December 15, 2025 to December 18, 2025 on 32 adult men and women aged 35 to 64, the VT Glutathione Tone-On Serum was evaluated for primary skin irritation including 8 hours of sleep. No irritation was observed at 30 minutes, 24 hours, and 48 hours after patch removal, with an average skin response degree of 0.00, classifying it as a low-irritation product.

Usage instructions

After cleansing and refining the skin texture with toner, dispense an appropriate amount and gently apply along the skin texture for absorption. For a natural tone-correction effect, apply a single layer. To increase tone-up and coverage effects, apply in thin layers 2 to 3 times. It can also be used before makeup as a long-lasting base prep.
