  10. What is the age for BPO?
    greater than 12yrs
  11. What is the MOA for salicylic acid?
    • Kearatolytic
    • Solubilizes intracellular cement
    • decreases corneocyte adhesion
    • Desquamation
    • Comedolytic
  12. What are the side effects of salicylic acid?
    • irritation
    • inflammation
    • erythema
    • salicylism---N/V/D, tinnitis, dizzieness (rare w/ topical)

    mild acne- less efficacious, fewer side effects, easier to use
  14. What are the directions for salicylic acid?
    Apply 1-3 times daily to clean dry skin (do not need to titrate but can for dryness)

    • Keratolytic
    • Inhibits anaerobic glycolysis (weak antibiotic)
    • Scavenger of oxygen free radicals (weak anti-infalmmatory)
  27. What are the side effects of Azelaic acid?
    • Irritation, Itching
    • Hypopigmentation- anti-tyrosinase and anti-mitochondrial enzymatic activities may interupt activity of normal melanocytes OR free radical scavengers cause hyperactivity of melanocytes
    • Transient--resolve in 1-2 weeks
  28. When to use azelaic acid?
    • mild to moderate acne
    • mono- for mild
