Study Notes
Acne Pathogenesis
- Acne involves four key mechanisms:
- Increased sebum production: Driven by androgens, leading to excess sebum from sebaceous glands.
- Follicular hyperkeratinization: Dead skin cells and sebum clog follicles, forming comedones (whiteheads/blackheads).
- Bacterial lipolysis: Cutibacterium acnes thrives in sebum, breaking it down and causing irritation.
- Inflammation: Dead skin cells and bacteria trigger an inflammatory response, creating lesions.
Acne Targets for Therapy
- Reduce sebum production.
- Normalize skin cell shedding.
- Control C. acnes growth.
- Minimize inflammation.
Acne Types: Vulgaris vs. Rosacea
-
Acne vulgaris:
- Linked to androgen activity.
- Characterized by comedones, papules, pustules, nodules, and cysts.
- Common in adolescents.
-
Acne rosacea:
- No comedones.
- Often triggered by alcohol, spicy food, or temperature changes.
- Common in adults (age 30+), with erythema, telangiectasia, and inflammatory lesions.
Acne-Inducing Medications
- Systemic corticosteroids (e.g., prednisone) can cause pustular acne.
- Antiepileptics (e.g., phenytoin).
- Lithium.
- Halogens (excess dietary iodine).
- Cosmetic ingredients (e.g., isopropyl myristate, cocoa butter, fatty acids).
Acne Palliative Factors
- Non-comedogenic moisturizers.
- Gentle cleansing.
- Balanced, low-glycemic diet.
Non-Pharmacologic Acne Management
- Gentle, fragrance-free cleansing twice daily.
- Avoid harsh scrubbing or friction.
- Use sunscreen (SPF 15+).
- Consider comedone extraction for visible lesions.
Moisturizers in Acne Treatment
- Moisturizers improve tolerance for acne treatments by reducing dryness.
- Choose moisturizers based on skin type:
- Dry skin: Nutrient-rich.
- Oily skin: Lightweight, oil-free.
- Combination skin: Light formulations for problem areas.
Acnegenic Sunscreen Ingredients
- Benzophenones (e.g., dioxybenzone, oxybenzone, sulisobenzone).
Acne Severity
- Mild: Few papules/pustules, no nodules.
- Moderate: Several papules/pustules, few nodules.
- Severe: Extensive papules, pustules, nodules, and/or cysts; scarring common.
Pharmacologic Acne Treatments
- Mild: Topical retinoids (e.g., tretinoin, adapalene), benzoyl peroxide (BPO).
- Moderate: Combination therapy (retinoid + BPO + topical antibiotic).
- Severe: Oral isotretinoin, oral antibiotics (e.g., doxycycline), hormonal therapy (female patients).
Pharmacologic Mechanisms
- Retinoids: Normalize skin cell shedding, prevent comedones.
- BPO: Antibacterial and comedolytic.
- Antibiotics: Reduce C. acnes and inflammation.
- Isotretinoin: Decreases sebum and normalizes skin cell shedding.
Topical Retinoids
- Adapalene (OTC).
- Tazarotene.
- Tretinoin.
- Trifarotene.
Acne Therapy Patient Counseling
- Retinoids: Night application, avoid spot treatment, expect initial worsening.
- BPO: Start at low concentration, avoid contact with clothing.
- Oral antibiotics: Take with water, avoid sun exposure (photosensitivity risk).
Topical vs. Oral Antibiotics
- Topical: Fewer systemic side effects, but risk of resistance.
- Oral: More effective for severe acne, but systemic side effects (photosensitivity).
Overcoming Antibiotic Concerns
- Combine with BPO to prevent resistance.
- Limit therapy duration (4 months).
- Transition to retinoid maintenance therapy.
Hormonal Therapy Patient Population
- Women with acne worsened by hormonal fluctuations (e.g., PCOS).
- Reduces sebum production by suppressing androgen activity.
iPLEDGE Program Goals
- Prevent pregnancy during isotretinoin treatment.
- Prevent pregnant people from using isotretinoin.
Acceptable Contraception for Isotretinoin
- Primary: Hormonal implants, IUDs.
- Secondary: Barrier methods, abstinence.
Isotretinoin Prescription Window Closure
- For women who can become pregnant, prescription must be filled within 7 days of the pregnancy test.
Evidence-Based Acne Treatment Plan
- Tailored to severity.
- Pharmacologic, non-pharmacologic, and monitoring.
- Seek care for worsening symptoms, serious side effects.
