  1. WHAT IS ACNE VULGARIS? Acne vulgaris is a common chronic

    skin inflammatory disorder of the pilosebaceous unit. Acne vulgaris is the medical name for common acne. It usually affects nearly 80% of persons at some time between the ages of 11 & 30 years but generally acne occurs in younger age because of earlier puberty. It results in disfigurement & permanent scarring. It can have serious adverse effects on psychosocial development, resulting in emotional problems, withdrawal from society & depression.
  2. There are six types of acne: 1.Whiteheads 2.Blackheads 3.Papules 4.Cysts

    5.Nodular 6.Pustules The first two types are non-inflammatory. These types of acne are usually easier to treat while the last four types are considered as inflammatory acne as these are difficult to treat. TYPES OF ACNE VULGARIS
  3. WHITEHEADS These are clogged follicles covered by a thin layer

    of skin that appear as white bumps or spots. They remain under the skin’s surface. Whiteheads are also known as closed comedones. It is important to note that whiteheads can’t be removed or fixed by squeezing them, so don’t try to pop them on your own.
  4. These are caused when pores are clogged due to debris

    & oil buildup. Blackheads look black on the skin’s surface. The black marking isn’t from dirt or infection but it is due to the sebum which oxidizes at the surface. They are known as open comedones because the head of the pore remains open, while the rest of the pore is clogged. Blackheads can be removed by squeezing, although that’s not recommended because it can cause scarring. BLACKHEADS
  5. PAPULES ➢inflamed lesions & blemishes ➢appear as red or pink

    bumps ➢visible on the skin’s surface ➢small ➢tender ➢sensitive
  6. CYSTS ➢very large ➢inflamed lesions ➢severe form of pimple ➢painful

    ➢soft ➢pus-filled lumps under the skin’s surface ➢clearly visible on the surface of the skin ➢most difficult acne to treat
  7. NODULAR ➢large ➢inflamed lesions ➢serious type of acne ➢painful lumps

    ➢hard ➢flesh or red colored bumps ➢deep under the skin’s surface ➢clearly visible on the skin surface
  8. PUSTULES These are small to fairly large, inflamed, bulging bumps

    which is red at their base & have pus at the top. These are clearly visible on the surface of the skin. Popping pustules may cause the bacteria to spread, so don’t try to pop or squeeze them.
  9. MICROORGANISM BEHIND ACNE VULGARIS Cutibacterium acnes or Propionibacterium acnes is

    a gram-positive, human skin commensal that prefers anaerobic growth conditions & is involved in the pathogenesis of acne. It is a pimple causing bacteria which lives on the skin & contributing to the inflammation & infections by converting the sebum (skin oil) into fatty acids.

  10. CAUSES OF ACNE VULGARIS ➢Excess sebum (oil) production ➢Hair follicles

    clogged by oil & dead skin cells ➢Keratinization (shedding dead skin cells) ➢Bacteria ➢Excess activity of androgen hormone ➢Stress ➢Certain medication (such as drugs containing corticosteroids, testosterone or lithium) ➢Diet (chocolate, skim milk, carbohydrate rich foods)
  11. ACNE It is a skin disease represented by follicular papules

    or comedones that in extreme cases may contain pus. It is developed when the follicles are blocked. It is more deeply rooted. It is seen in children during puberty. It is usually comes with a genetic predisposition but many other factors are also involved. It is a skin lesion that takes on a rounded, somewhat bumpy appearance. It often results when the pores of the skin is blocked. These are small, red, inflamed & infected plugged oil glands, sometimes filled with pus. They appear on the skin surface. It is one of the symptoms of acne. PIMPLE
