Dermal Acceptability Evaluation in Sensitive Skin

The goal of this clinical trial is to evaluate the dermatological safety and acceptability of a cosmetic product in participants with sensitive skin. The main questions it aims to answer are: * Does the investigational product demonstrate dermatological acceptability in participants with sensitive skin under normal conditions of use? * Does the investigational product present a low risk of skin irritation? * What discomfort sensations, if any, are reported by participants with sensitive skin during product use? Participants will: * Apply the investigational product to the face and body twice daily under normal conditions of use. * Undergo clinical dermatological evaluations to assess signs of irritation and product tolerability. * Report any discomfort sensations experienced during the study period. The study will enroll 33 healthy male and female participants aged 18 years or older with sensitive skin confirmed by a positive Stinging Test. This is a single-center, single-blind clinical trial designed to evaluate the dermatological safety of the investigational product through clinical dermatological assessments under real-world conditions of use.

Inclusion Criteria: * Male and female participants aged 18 years or older. * Participants with sensitive skin, clinically confirmed by a positive Stinging Test. * Participants with any skin type (combination, oily, dry, or normal skin). * Intact skin in the assessment area. * Willingness to comply with all study procedures and attend the study site on the scheduled dates and times for assessments. * Ability to understand the study requirements, provide written informed consent, and sign the Informed Consent Form (ICF). Exclusion Criteria: * Pregnant or breastfeeding women, or women at risk of becoming pregnant during the study, when applicable. * Use of anti-inflammatory, immunosuppressive, or antihistamine medications within 3 weeks prior to screening. * Skin conditions or marks in the test area that may interfere with the evaluation of potential skin reactions, including vascular malformations, scars, excessive hair growth, multiple nevi, or sunburn. * History of atopy or allergic reactions to cosmetic products. * Active skin diseases and/or lesions (localized or widespread) in the assessment area. * Immunosuppression due to medication use or active disease. * Uncontrolled endocrine disorders. * Relevant medical history or current evidence of alcohol or substance abuse. * Known history of or suspected intolerance to products of the same category. * Intense sun exposure within 15 days prior to assessment. * Aesthetic or dermatological treatments within 4 weeks prior to assessment. * Any other condition that, in the investigator's opinion, may reasonably justify exclusion from the study.
