ACNE


Acne is a common disorder affecting up to 20% of teenagers  and has recently shown an increase  prevelance in adults. It is a disorder of the pilosebaceous units characterized by the presence of papules, pustules and comedones (blackheads/whiteheads) on the face, trunk and upper back.

 

What is the cause of acne?


1. An increase in sebum production. Sebum is a substance produced by the oil glands. An overproduction of this substance leads to the production of fatty acids. It also acts as a nidus for the production of bacteria that eventually leads to the development of acne.


2. Cornification of the pilosebaceous unit. Thickening and plugging of the hair follicle and sebaceous glands by keratin leads to occlusion and hence the development of acne.


3. An increase in androgen production. An increase in androgens leads to a hormonal imbalance, which aggravates acne.


4.Proliferation of bacteria.There are bacteria in the skin that contribute to the development of acne, by aggravating inflammation and leading to pustule formation.


What are the clinical features of acne?


An acne patient usually presents with oily skin. The patient may present with papules, pustules, comedones, nodules and cysts involving the face, chest and upper back. There are variable degrees of scarring, pigmentation and uneven skin tone depending on the severity and type of acne.


REMEMBER THE FOLLOWING FACTS:


1.     Use a hypoallergenic, non comedogenic cleanser and moisturizer
2.     Do not pick or squeeze your pimples. It only serves to aggravate scars
3.     Remember, that there is no quick fix solution in the treatment of acne
4.     Remind yourself that acne is not a phase and therefore if untreated, will progress into adulthood with  
        scarring
5.     Treatment options include topical keratolytics, comedolytics, systemic antibiotics, oral contraceptive pills
        and isotretinoin
6.     Consult your practitioner or dermatologist early to prevent the sequelae ie. scarring and pigmentation from
        acne.
