Is this mask suitable for sensitive skin? — Carbon based rejuvenating face mask ugol proff 50ml

This mask contains tea tree essential oil and strongly absorbent minerals (charcoal, clay, thermal mud), which can be too intense for thin, reactive, or easily reddened skin. If you have sensitive skin, start with caution. Do a patch test 24 hours before your first full use: apply a small amount to a discreet area like the jawline or behind the ear, and watch for any redness, itching, or stinging. If you have a known allergy to essential oils, avoid this product. Never apply the mask to irritated, sunburned, or broken skin. During use, if you feel a strong burning sensation or see significant redness, rinse it off immediately. After rinsing, if your skin feels overly tight or uncomfortable, reduce the frequency to once a week or stop entirely. For those with normal or combination skin, it's generally well tolerated, but patch testing is always a sensible step before using any new active mask.
