What are the causes of Acne?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Acne is a genetic disorder and it is estimated that about 95% of all females will have acne at some point in their lives. What we see with acne is a blockage of the glands associated with acne and some skin inflammation. With this there is growth of a certain bacteria in the gland that gives us the inflammatory skin lesions of acne, and then excess sebum from the glands. All of these contribute to why we get acne. The myths that foods and sodas and chocolates for the most part have been thrown out – it is genetics with hormonal influences that causes most acne. A board certified dermatologist can work with you to minimize your acne and show you the new and exciting treatments that are now available.

Genes, foods, stress, hormones, products, medication and bacteria all play a part. 

To be scientific-acne occur because of -

1. Blockage of the pilosebaceous units

2 . Inflammation of the skin

3. Bacterial proliferation (leading to p. acnes proliferation)

4 .Excess oil production or sebum 

Addressing these factors will result in improvement or cure. 
Diet seems to play a role in some, but not all patients.

Acne is a skin disease with many causes. Genetic factors such as the tendency for skin cells in the hair follicle to be sticky play a role. Hormonal factors, which can result in increased oil production, contribute. And other factors that increase inflammation , such as bacterial and perhpas one's diet, also play a role. This is why is it best to get your acne treated by a board-certified dermatologist who is familiar with different approaches.

There are many causes of acne.  Now that there are so many wonderful treatments, no acne should be permanent, nor the scars as a result of acne.  Acne can be inherited or can be a result of a hormonal imbalance, or an infection.  For the best treatment options, please find a board certified dermatologist in your area.

Thank you for your question. There are four main causes of acne: increased oil production, clogged pores, bacteria, and inflammation which are due to hormonal shifts in the body. Acne is partly inherited and most people outgrow it after their teenage years. I hope this helps.

Acne Has Multiple Causes

Dysfunction of the the follicle/pore/sebaceous gland unit is the common cause. This includes a P. acne bacterial component, inflammation, dyfunction of the oil gland, and a hormonal component. Multi-modality treatment of the causes is most effective in the long run.  Active management can prevent permanent scarring and psychlogical stress. Best wishes.

Common Causes of Acne

Acne occurs when pores get clogged in the skin. These pores have ducts connected to  oil glands underneath the skin. A number of things can block these pores including dead skin cells and oil. When the pores get blocked, the body can also produce inflammation around these areas. Greasy moisturizers and heavy make-up can block these pores. As well, bacteria in the skin, hormone fluxes, and stress can all make acne worse. Talk to your dermatologist about your skin can. They can help you find your acne's trigger and individualize the right treatment for you.

  Acne is extraordinarily common, and may affect 80% of all teenagers across racial, ethnic, and geographical lines.  Perhaps no affliction causes more psychic harm than acne does.  It is due to excess secretion of the sebaceous glands, and this is under hormonal influence, explaining the common onset of this disease with puberty.  There are many forms of treatment depending on the severity of the problem.
