First, let’s talk about what causes acne. Pimples form when the oil and dead skin cells on your skin combine to form a plug that blocks the pores. “As the P. acnes bacteria that naturally live on skin overgrow within this plugged follicle, the area becomes inflamed and this is when you start to see papules, pustules, and cystic lesions,” RealSelf dermatologist Sejal Shah, M.D., tells SELF. The treatments ahead work to exfoliate away dead skin cells, suck up excess oil, stop inflammation, and kill the P. acnes bacteria. There are even a few treatments that target hormonal acne specifically.
Tea tree oil is renowned for being good for your skin. In addition to this, it also contains anti-bacterial and anti-fungal properties, which makes it highly beneficial for acne treatment. In fact, studies that compare tea tree oil to the acne medication benzoyl peroxide shows it to be just as effective. But please remember to dilute tea tree oil before you use it; otherwise, your skin may get irritated.
Your pimples need TLC, too. The study on acne vulgaris found that, in an attempt to dry out acne lesions, patients often use too many products or apply excessive amounts to problem areas, resulting in further irritation and over drying of the skin. Vigorous scrubbing and using harsh exfoliants can make acne worse by rupturing whiteheads and blackheads, turning them into painful red ones. And remember: no matter how satisfying it is, picking and popping your zits will also increase inflammation and opportunity for infection.
Acne vulgaris is diagnosed based on a medical professional's clinical judgment. The evaluation of a person with suspected acne should include taking a detailed medical history about a family history of acne, a review of medications taken, signs or symptoms of excessive production of androgen hormones, cortisol, and growth hormone. Comedones (blackheads and whiteheads) must be present to diagnose acne. In their absence, an appearance similar to that of acne would suggest a different skin disorder. Microcomedones (the precursor to blackheads and whiteheads) are not visible to the naked eye when inspecting the skin and can only be seen with a microscope. There are many features that may indicate a person's acne vulgaris is sensitive to hormonal influences. Historical and physical clues that may suggest hormone-sensitive acne include onset between ages 20 and 30; worsening the week before a woman's period; acne lesions predominantly over the jawline and chin; and inflammatory/nodular acne lesions.
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
