Acne and Overactive Sebaceous Glands: Pathogenesis and Treatment

Yes, hyperactive sebaceous glands are a primary driver of acne vulgaris.

Pathogenesis (Four Pillars)

1. Excess sebum production: Androgen-stimulated (puberty, PCOS, adrenal hyperplasia).
2. Follicular hyperkeratinization: Abnormal desquamation → microcomedone.
3. Cutibacterium acnes proliferation: Thrives in lipid-rich, anaerobic follicle.
4. Inflammation: Innate/adaptive response to C. acnes and follicular rupture.

Treatment Targeting Sebum

• Topical retinoids (adapalene, tretinoin): Normalize keratinization, reduce microcomedones, some sebostatic effect.
• Oral isotretinoin: Only drug that permanently reduces sebaceous gland size/activity; for severe/nodular/scarring acne.
• Hormonal therapy (females): Combined OCPs (↓ ovarian androgens), spironolactone (androgen receptor blocker).
• Topical anti-androgens: Clascoterone cream 1% (FDA-approved).

Adjunctive

• Benzoyl peroxide (bactericidal, anti-inflammatory).
• Topical/oral antibiotics (limit duration, combine with BP to prevent resistance).
• Gentle skincare, non-comedogenic products.

Multimodal therapy tailored to severity and patient factors yields best outcomes.
