Rosacea

Etiology

Liletta (levonorgestrel 52 mg) had the highest incidence of rosacea at all time points (1, 3, and 5 years post-insertion), followed by Mirena, while Skyla (lower-dose levonorgestrel) showed no significant association. Hormonal IUDs, particularly higher-dose levonorgestrel devices, may increase the risk of rosacea, likely due to hormonal modulation of androgen and estrogen receptors, whereas nonhormonal IUDs were not linked to increased risk.

70.5% of patients report that diet impacts disease severity of rosacea. (37892480)
Foods for which there is some evidence (although limited in its scope and certainty) for exacerbation or development of rosacea include: (35096255)
- alcohol (most frequent purported trigger)
- spicy foods
- cinnamaldehyde-containing foods: tomatoes, citrus fruits, chocolate
- hot drinks
- histamine-rich foods: aged cheese, wine, processed meats
Coffee and caffeinated beverages, which were thought to be trigger appear not to be and may be protective. (30347034)
For patients with ocular rosacea, supplementation with omega-3 fatty acids may be affective. (27050028)
