FAQ's About Acne

What does Acne Look Like and Where Does It Appear Most?


Acne mostly affects the face, but also on the neck, chest, and back. It appears as inflamed papules and pustules or pimples.


Comedones, commonly known as blackheads and whiteheads, are also associated with acne. Finally, acne can lead to skin color changes and cause scarring

Food and Acne—Is There A Link?


There are some studies that suggest a link between acne and the foods we eat. Several of these studies have shown benefits to those dealing with acne to eat a low-glycemic, low protein, low fat, and low dairy diet. It all has to do with food’s effect on insulin and insulin-like growth factor-1.


Although cow’s milk does have a low glycemic index, it does contain estrogen, androgens, progesterone and glucocorticoids. These all provoke how skin cells mature, as well as sebum production.

Why Is Acne Worse For Some But Not Others?


It comes down to genetics and hormones. If your family members had trouble with acne, most likely, you will, too. With puberty comes hormonal changes and that can compound the problem. Menopause can also trigger acne.
