MODERN VIEW OF ACNE VULGARIS (ACNE)
Now in this world every adult faces the problem which is ACNE . let we see what are the modern aspesct of acne like factors causing acne, pathophysiology, stages ,treatments... come on let we go inside it

15% younger 35 age
3% older than 35 ( women)
ACNE
a skin condition characterized by red pimples on the skin, especially on the face, due to inflamed or infected sebaceous glands and prevalent chiefly among adolescents.
FACTORS AFFECTING ACNE
- Harmones
- genetics
- puberty
- diet (chocolate,lipids, milk)
- bacteria
BACTERIA WHICH CAUSES ACNE
- Propionibacterium
- cutibacterium
VITAL DIGNOSTIC POINTS
- Mainly seen over face, chest, back
- black heads with papules , pustules
- in severe cases cysts, scars
ACNE
Acne is non inflammatory or inflammatory depends on what stage of acne
- Initial phase this pimple is in non inflammatory form but when it pops out their small inflammatory reaction takes place
SKIN
skin consist of dermis,epidermis,sebaceous gland ,This sebeceous gland secrete sebum which protect lubricate hair and skin
PATHOLOGY OF ACNE
- There can be hypertrophy(Hypertrophy: Enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells)of sebaceous gland .which cause over production of sebum .this hypertrophy is caused by particular harmone particularly ANDROGEN such as TESTOSTERONE.
- Hyper keratinization (Hyperkeratinization is a disorder of the cells lining the inside of a hair follicle. This excess of keratin, which is influenced by genetics, results in an increased adherence/bonding of dead skin cells together.) of epithelial cells in epidermis which will lead to the obstruction of sebaceous follicle so sebum will accumulate in this area which cause comedo
COMEDO
comedo consist of pimples, contain oil sebum, kerartinized cells,together bacteria , fatty acids( p.acne feed on triglycerides in sebum which catalyst fatty acid which produce lot of sebum)
TYPES OF COMEDO
- White heads
- Black heads
BLACK HEADS
Blackheads are small bumps that appear on your skin due to clogged hair follicles. These bumps are called blackheads because the surface looks dark or black. Blackheads are a mild type of acne that usually form on the face
Open comedo form black head because their is direct exposure of oxygen
WHITE HEADS
Whiteheads are small, white, raised bumps on the skin. They form when oil and skin collect in the pores. Whiteheads are also known as closed comedones and pimples. They occur with acne, often on the face, chest and back
COMEDONES (FINAL STAGE)
Comedons will rupture and cause inflammation and causes scarring happen . while rupturing the sebum in it will spill ot everywhere in skin and triggers inflammation.
STAGES OF ACNE
- COMEDONS
- PAPULES ( small pimple or swelling on the skin, often forming part of a rash)
- Pustules(a small blister or pimple on the skin containing pus)
- Nodules(A nodule is a growth of abnormal tissue. Nodules can develop just below the skin. They can also develop in deeper skin tissues or internal organs. general term to describe any lump underneath the skin that's at least 1 centimeter in size.)
- cysts(Cysts are closed capsule or sac-like structures, typically filled with a liquid, semisolid, or gaseous material, much like a blister. Cysts vary in size from microscopic to very large. Very large cysts can displace internal organs. The majority are benign, but some cysts can be cancerous or precancerous.)
TREATMENT FOR ACNE
3 GROUPS
- Retinoids
- antimicrobial
- harmonal therapy
RETINOIDS
Derived from vitamin a
MAIN TARGET
Suprabasal keratinocytes (epidermal cell)
EXAMPLE
EXTERNAL APPLICATION
- Tretinoin
- adpelene
- Tazarotene
SIDE EFFECT
- Skin dryness
- irritation
- redness
- swelling
- blistering
- sensitivity to light
ORAL RETINOID
- Isotretinoin( inhibits proliferation and differentation of sebum producing cells which cause shrinkage of sebaceous gland,decrease sebum production, reduce colanization with p.acnes)
SIDE EFFECTS
- Cause birth defect should avoided in pregnancy
- mood changes
- gastrointestinal disorder
ANTI MICROBIALS
MAIN TARGET
Inhibits growth of susceptible acne
It target p.acne
EXAMPLE
- TRIMETHOPRIM
- SULFAMETHOXAZOLE
- MINOCYCLINE
- ERYTHROMYCIN
- AZITHROMYCIN
- CLINDAMYCIN
- DOXYCYCLIN
- SULFAMETHOXAZOLE
SIDE EFFECT
ORALLY:
- Nausea
- vomiting
- diarrhea
EXTERNALLY
- DRYNESS
- REDNESS
- ITCHING
Overuse of antibiotic can promote the growth of bacteria
BENZOYL PEROXIDE
Release oxygen radicles to the pores
SIDE EFFECT:
- Dryness
- Redness
- Itching
- Burning sensation
HORMONAL THERAPY
MAIN TARGET:
- Regulate androgen
- sebocyte
EXAMPLE
- Spironolactone is used to block androgen receptors with sebocytes
CHEMICAL PEELS
chemical peel is a procedure in which a chemical solution is applied to the skin to remove the top layers. The skin that grows back is smoother
1.Glycolic acid peels
2.salycylic acid peels
3. mandelic acid peels
LASER
