Acne

  1. 1. Acne Bill V. Way, D.O. Dermatology Residency Program Director
  2. 2. What is Acne?  Acne is a skin disorder resulting from the action of hormones on the skin’s oil glands (sebaceous glands) which leads to plugged pores and outbreaks of the lesions of papules, pustules, comedones, inflammatory cysts commonly called pimples or zits.
  3. 3. Acne  Over 17 million people in the US have acne today. It is the most common skin disease.  Not a serious health threat, but severe acne can lead to disfiguring, permanent scarring, low self esteem.
  4. 4. Acne  The disease of the pilosebaceous units of the skin.  Most commonly on the face, neck, chest, back and shoulders were more of the pilosebaceous units are located.
  5. 5. Acne  The basic acne lesion is called the comedo (KOM-e-do), simply an enlarged and plugged hair follicle.  If it remains below the surface it is called a closed comedo and produces a whitish bump called a whitehead, this is not a milium.
  6. 6. Acne: Comedo  If the comedo reaches the surface, it is called an open comedo or blackhead  The black color is not dirt, but is from the oil oxidizing when it reaches the surface of the skin
  7. 7. Acne: Papule  Inflammed lesions that usually appear as small pink bumps on the skin and may be tender to the touch
  8. 8. Acne: Pustule  Inflammed papules with a pustule on the top that may be red at the base and usually tender. (Pimple)
  9. 9. Acne: Nodules  Large, painful, solid lesions that are lodged deep within the skin
  10. 10. Acne: Cysts  Deep,painful, pus-filled lesions that can cause scarring
  11. 11. What causes Acne?  Exact cause of acne is unknown. Several factors may play a role.  One important factor is an increase in androgens (male hormones). These increase in both boys and girls during puberty and cause the sebaceous glands to enlarge and make more sebum.
  12. 12. What causes Acne? Other factors: heredity or genetics; medications, androgens, lithium; greasy cosmetics; occlusive clothing  Hormone changes related to pregnancy or starting and stopping birth control pills can also be a cause of acne.
  13. 13. What causes Acne?  Propionibacterium acnes (P.acnes) are the anaerobic bacteria responsible for causing acne.  Other factors: heredity or genetics; medications, androgens, lithium; greasy cosmetics; occlusive clothing  Hormone changes related to pregnancy or starting or stopping birth control pills can also be a cause of acne.
  14. 14. Propionibacterium acnes  Anaerobic bacteria in hair follicle.  These bacteria use the sebum as food and break the sebum down into irritating substances, which cause inflammation.  The abnormal flaking of the cells inside the hair follicle and the irritating substances lead to a plug formation and the to follicle swelling and then rupturing and developing into the papule then to the pustule.
  15. 15. What can make Acne worse?  Changing hormone levels in adolescent girls and adult women 2-7 days before their menstrual period starts  Friction by leaning or rubbing skin  Pressure from helmets, backpacks  Environment: pollution and high humidity  Squeezing or picking at pimples  Hard scrubbing of the skin
  16. 16. Myths about causes of Acne  Foods; chocolate, greasy or fried foods. No foods cause acne.  Dirt. Acne is not the result of uncleanliness or infrequent washing.  Stress. Just the opposite, Acne may cause the patient more stress.  Sunlight or tanning clears acne. No tanning will lead to sundamaged skin, wrinkles and skin cancers.  Skin must be scrubbed. No, too much scrubbing may actually make acne worse.
  17. 17. Who gets Acne?  People of all races and ages.  Most common in adolescents and young adults  85% between ages 12-25  Resolves with time around age 25-30  Few patients may have persistent acne into their 40’s and 50’s
  18. 18. Who should be treating Acne?  Family Practice  Pediatrics  Internal Medicine  Dermatology
  19. 19. What are the goals in treating Acne?  Heal existing lesions  Stop new lesions from forming  Prevent scarring  Minimize the psychological stress and embarrassment, thus improving self-esteem and self-confidence and avoiding depression  Teach the patient what acne is, how to treat their acne and what to expect from treatment
  20. 20. Acne Treatment  Medical treatment is aimed at reducing several problems that play a role in causing acne; abnormal clumping of cells in the follicles, increased oil production, bacteria and inflammation.
  21. 21. Grading Acne  Scale 0-4  0 – no acne, clear  +1– mild acne, comedos, papules, few pustules  +2 – moderate acne, comedos, multiple papules and pustules  +3 – moderately severe, multiple comedos, papules and pustules, mild scarring  +4 – severe, multiple comedos, papules, pustules, inflammatory cysts, nodules, scarring
  22. 22. Treatment for Blackheads, Whiteheads and mild inflammatory Acne  OTC or Rx  Benzoyl peroxide, resorcinol, salicyclic acid and sulfur  Benzoyl peroxide products kill P.acnes and may reduce oil production  Resorcinol and salicyclic acid and sulfur help break down blackheads and whiteheads
  23. 23. OTC Treatment  Benzoyl peroxide washes and gel  Salicyclic Acid washes  Must be used twice daily regularly for 8- 12 weeks, then reevaluate
  24. 24. Treatment of Moderate to Severe Inflammatory Acne  Prescription topical and or oral medications alone or in combination  Recheck patient every 4-8 weeks for results and to adjust acne treatment program
  25. 25. Treatment of Severe Nodular or Cystic Acne  Should be seen and treated by a dermatologist  Failure to respond to a variety of topical antibiotics, topical retenoids and oral antibiotics  Consider Accutane Therapy
  26. 26. OTC Topical Acne Cleansers  Neutrogena Acne Wash  Cetaphil Facial Cleanser  Oil of Olay Facial Cleanser  Various Benzoyl Peroxide Cleansers, Clearsil, Clean and Clear, others
