                                According to the National Rosacea Society, over 16 million Americans are affected by rosacea, a chronic skin condition that is often the underlying cause of persistent facial redness. While rosacea is not caused by a single **deficiency**, specific nutritional shortfalls, such as a lack of niacin or zinc, can present with similar symptoms or exacerbate existing skin conditions. Addressing the root cause, whether nutritional or otherwise, is key to managing facial redness.
