8. Female participant of childbearing potential has had a negative serum pregnancy test at screening and a negative urine pregnancy test at Day 1.

9. For female participant of childbearing potential involved in any sexual intercourse that could lead to pregnancy: the participant must agree to use a highly effective contraceptive method from at least 4 weeks prior to Day 1 until at least 6 months after the last study product application.

Participants will be instructed not to apply these products on the treated areas within approximately 30 minutes before and after study product application.

12. Participant is willing to limit or avoid known personal triggers of rosacea (eg, spicy foods, consumption of alcoholic beverages, extended intentional sun exposure, tanning beds, sauna, etc) for the duration of the study.

13. Participants must be willing to comply with all study procedures and must be available for the duration of the study.
