Acne rosacea has become a more commonly diagnosed skin disorder in recent years. Although the cause of the disorder is not known, it is often thought in alternative medicine to be connected to excess heat in the body. No cure is yet available, but certain foods, particularly ones that are cooling, have been shown to decrease symptoms. Several nutrient-rich juices in particular can help with acne rosacea, including pineapple, lemon and dark grape juices.

Rosacea is often linked to inadequate digestion in alternative medicine literature. Foods not properly broken down can cause a host of problems in the stomach and digestive tract. One juice in particular that works directly on digestion is pineapple, as according to the Encyclopedia of Natural Healing, it contains an enzyme that aids in protein digestion.

Grapes contain a high amount of bioflavonoids, which are known to strengthen blood vessels, according to the Healing Daily website. Blood vessel damage is a primary component of rosacea, so drinking grape juice daily can help with protecting weakened vessels.

Lemons are a naturally alkalizing food, and they cool the body when taken in juice form. Nutritionist Rudy Silva notes lemon juice, used often in cleansing, is one of the best juices for skin health. He adds that it will eliminate acid waste and also help to clear acne, which is often present alongside rosacea.
