This is a rinse-off mask designed for occasional use when your skin feels particularly dry, tight, or tired. As the formula is concentrated for quick hydration, a typical application time is between 5 to 15 minutes. Leaving it on longer than 20 minutes is generally not recommended, as it does not provide additional benefits and could potentially lead to irritation for some skin types, especially if the skin is already sensitive or reactive.
Regarding frequency, it fits best as an extra hydration step, not a daily treatment. Using it 1 to 3 times per week is sufficient for most people, depending on your skin's current condition and needs. For instance, you might use it after a day of travel or exposure to sun and wind, or before makeup if your skin looks flaky. It's important to observe how your skin responds; if you notice any signs of sensitivity, reduce the frequency. Always patch test the product on a small area of your skin before the first full application, especially if your skin is prone to reactions.
The 10 ml sachet is practical for one or two uses. After opening, use the entire contents or seal it tightly for a second use within a day or two to prevent the formula from drying out or becoming contaminated.
