Best Blemish Buster: Vitamin A


Typically, the lining of an oil gland is meant to exfoliate daily. Skin cells and excess oil exit the gland through the pore and are cleansed away. In acne-prone skin, however, there is a “stickiness” of this inner lining that leads to plugged oil glands beneath the surface of the skin. Eventually, there is a build-up of oil, cellular debris and bacteria which leads to inflammation and the appearance of a pimple

Vitamin A helps normalize the production of the oil gland lining, “unsticking them,” so to speak. Eating foods rich in vitamin A helps improves cellular turnover and reduces breakouts.

Food source: Half a cup of collard greens has 441 mg of vitamin A, the equivalent of 7917.12 IU and just 24 calories. Half a cup a week helps keep skin blemish-free.

Reduce Redness and Inflammation: Quercetin


Redness and inflammation of the skin can be the result of many things, including rosacea, sun damage, a change of season or perimenopause. Many cultures have found a variety of botanicals and herbs that work to calm the skin and reduce the appearance of redness.

Quercetin is a plant-derived flavonoid that has been shown to both calm inflammation and also has an antihistamine-type of action. Quercetin helps support the immune system against infections, free radicals, allergies and inflammatory responses such as arthritis.

Food source: One of the best sources of quercetin is the tiny caper. Don’t let their small size fool you. One tablespoon of capers contains 187mg of quercetin. Sprinkle a tablespoon over an entrée twice a week to banish skin redness.
