A single session with the Yusezen facial mask takes 15 minutes after opening. The device automatically shuts off after this time. Regular use 3–4 times a week is recommended. You can increase or decrease the frequency of use depending on your skin condition.
What is the recommended duration and frequency of use?
I feel different sensations on my right and left faces, is this normal?
Facial muscles can naturally be asymmetrical. You can achieve balance by adjusting the EMS levels on the right and left sides of the mask separately.
How much serum or lotion should I use with the mask?
To maximize the effects of EMS technology, it's important for your skin to be moist. Apply a sufficient amount of water-based serum, essence, or moisturizer before your session. If moisture is low, a tingling sensation may occur.
Is the mask water resistant? Can it be used in the bathroom?
No. The mask is not waterproof, so it should not be used in the bath or shower.
Can I use the device while sleeping?
The device should not be used during sleep. Sessions should be limited to 15 minutes.
Can I have more than one session per day?
One session (15 minutes) per day is ideal. If you want to use it more, it is recommended that you leave at least 5 hours between sessions.
I feel a slight pain in my teeth, is it normal?
EMS waves may cause mild discomfort for individuals with fillings or dental treatment. If discomfort persists, discontinue use and consult your dentist.
Can I use it while pregnant or breastfeeding?
It is not recommended for use during pregnancy and the first postpartum period. Consult your doctor.
Can it be applied after shaving or to sunburned skin?
Do not apply to irritated, cut, or sunburned skin. Continue use only after the skin has fully healed.
