- Use of topical glucocorticosteroids applied to the face within 2 weeks of initial study visit
- Any prior treatment with lasers, intense pulsed light, photodynamic therapy, or other energy based therapy to the face.
- Facial hair, tattoos, facial characteristics, or cutaneous disease (such as actinic damage, melasma, postinflammatory hyper- or hypopigmentation, excessive telangiectasias, nevi, or other pigmentation) which may interfere with assessments of erythema in the opinion of the investigators.

Placebo Arm
This is a randomized vehicle controlled, double blinded, interventional study. Patients of East Asian descent with a history of Asian Flushing Syndrome will be asked to apply a thin layer of brimonidine 0.33% gel to one half of their face thirty minutes before consuming alcohol (1.5 oz vodka for women, 3.0 oz vodka for men). The Photos will be taken 30 minutes, one hour, and 1.5 hours after consumption of alcohol. Erythema will be assessed at each time point by both the patient and study investigator using a 5- point erythema assesment score. Patient blood alcohol content (BAC) will be measured noninvasively at each time point.
