This is a great question and there are many factors to consider when answering. We want to mirror as closely as we can the time of day and weather conditions of your event date. If your event is in the morning, your trial will be in the morning. If your event is in the winter, your trial will need to be in the winter. Ideally, we have 30 days prior to your event so that if a skin care regimen is recommended, your skin has time to respond prior to your special day. Get your trial prep sheet HERE.
