Mask Instant Clinical Study

The goal of this clinical study is to evaluate the soothing effect of the test product within 2 hours after a single application by measuring changes in multiple indicators before and after product use. It will also assess the safety of the test product. The main questions it aims to answer are: * Does the test product relieve skin irritation and reduce skin redness within 2 hours after single use? * What adverse skin reactions do participants experience after using the test product? Researchers will compare the treated half-face with the untreated contralateral half-face (split-face control) to verify the soothing efficacy of the test product. Participants will: * Receive skin redness induction on both cheeks, then apply the test product on one side of the face * Undergo skin assessments at baseline before redness induction, post-induction, and at 10 seconds, 1 minute, 5 minutes, 10 minutes, 1 hour and 2 hours after product application * Complete clinical evaluation, instrumental measurement, image analysis and self-assessment questionnaires at each time point
