Clinical Trial Summary

The purpose of this trial is to evaluate 1) the dermatological tolerability of 2 facial sunscreens after 21 (+2) days of use under normal conditions on the half face by adult subjects with sensitive skin, 2) Compare the efficacy of investigational products (IPs) after 21 (+2) days of use in adult subjects with sensitive skin, under dermatological supervision through the following evaluations: the transepidermal water loss in the nasolabial region; the sensory perception of the subjects using the sensory perception questionnaire, after 21 (+2) days of use under normal conditions; the sensitivity of the subjects' skin after the first application of each product using a questionnaire on the perception of signs of discomfort.

Exclusion Criteria:

• Participants that have had allergies or adverse reactions to common topical skincare products, including sunscreens, medications, or other products that the investigator considers relevant

• Participants that present a skin condition that may influence the study results (specifically psoriasis, eczema, atopic dermatitis, cutaneous xerosis, intense erythema, or active skin cancer). Mild erythema and xerosis associated with a sensitive skin condition are acceptable for eligibility

• Participants that present primary/secondary lesions (for example: scars, ulcers, vesicles, vitiligo) or tattoos on the test areas

If an individual is taking one of these medication types, the individual is not considered eligible at screening. However, if a subject begins using one of these medications during the study, the study physician should be consulted to consider the impact of the specific medication on subject safety and/or the study results, as described in section "Concurrent/Concomitant Medication"

• Participants that are self-reported to be pregnant or planning to become pregnant during the study

• Participants that have a history of a health condition/situation which may put the individual at significant risk, influence the study results, or interfere significantly with the individual's participation in the study

• Participants that are simultaneously participating in any other study

• Participants that are employees/contractors or immediate family members of the principal investigator (PI), study site, or sponsor

• History of non-adherence or unwillingness to adhere to the study protocol

• Any condition not previously mentioned that, in the opinion of the PI, may compromise the study evaluation

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Dermatological Tolerability	Change from baseline in dermatological tolerability will be reported. Dermatological tolerability includes a clinical assessment of the participant's initial skin condition, carried out by the study dermatologist according to the Skin Reaction Intensity Assessment Scale. Skin reaction intensity assessment of erythema, edema, blistering and peeling on the face will be done. Each skin reaction was scored on 4-point scale 0 = absent, 1 = mild, 2 =moderate, and 3 = intense. A decrease in score at post-baseline timepoints compared to baseline indicates an improvement.	Baseline (Day 1), Day 21
Primary	Change From Baseline in Skin Barrier Integrity	Change from baseline in skin barrier integrity will be reported. The facial skin barrier will be assessed by a trained technician using instrumental measurements with the Tewameter TM 300. The Tewameter measures transepidermal water loss (TEWL) that is the flow of water out of the skin. TEWL measurement will be taken in the nasolabial region of each half of the face.	Baseline (Day 1), Day 21
Primary	Number of Participants With Sensory Perception as Assessed by Sensory Perception Questionnaire	Number of participants with sensory perception as assessed by sensory perception questionnaire will be reported. The sensory perception of each sunscreen will be concluded from the data obtained from the sensory perception questionnaire which includes overall satisfaction, skin and eye irritation, comfort and other characteristics (stickiness, lightness etcetera). Sensory perception questionnaire includes 1 question on overall satisfaction with sunscreen by scoring on a scale ranged from 1 to 7, 1= disliked very much and 7= liked very much; 3 questions with participant's response on "does not irritate the skin, eye and felt comfortable using the sunscreen" on a response scale ranging from 1 to 5, 1= strongly disagree and 5= strongly agree; and 1 question that correlate the characteristic (stickiness, lightness etcetera.) with each product tested.	At Day 21
Primary	Number of Participants With Skin Sensitivity as Assessed by Discomfort Questionnaire	Number of participants with skin sensitivity as assessed by perception questionnaire on discomfort signs will be reported. Assessment of skin sensitivity after application of each sunscreen will be concluded from the data obtained by filling in the questionnaire on the perception of signs of discomfort. Perception questionnaire on discomfort signs includes sensation of discomfort, burning sensation, itching, redness sensation on skin and eye irritation. For each sign the participant will select a response on a scale ranging from 0 to 9, where 0 = no discomfort sign and 9= intense discomfort sign. Higher score indicates intense discomfort sign. If a participant has a moderate or/to intense reaction (from 4 to 9) an adverse event will be open.	At Day 1
Primary	Number of Participants With Adverse Events	Number of participants with adverse events will be reported. An adverse event is any untoward medical occurrence in a clinical study participant temporally associated with the clinical investigation, whether or not the event has a causal relationship to the participants' participation in the trial. It is therefore any unfavorable and unintended sign (including an abnormal finding), symptom, or disease that occurs during the trial. This can include any occurrence that is new in onset, an aggravation of severity/frequency of a baseline condition, or abnormal results of diagnostic procedures, including laboratory test abnormalities.	Up to Day 21
