Acne is a complex skin condition involving excess oil production, thickening of the skin’s outer layer, bacterial growth, and inflammation. In males and females, natural hormones like testosterone and dihydrotestosterone (DHT) are involved in developing acne. When DHT binds to receptors, this complex moves into the nucleus, promoting genes that lead to acne-related effects like sebaceous gland growth, oil production, and inflammation. Clascoterone blocks androgen receptors, preventing DHT from binding and reducing the signaling that triggers acne.
Clascoterone can also block DHT’s effects on androgenic alopecia, as DHT interactions in hair follicles contribute to hair loss. By inhibiting DHT from binding to scalp androgen receptors, clascoterone reduces androgen receptor-related gene expression and IL-6 production.
Acne, commonly referred to as acne vulgaris, is a skin condition that arises when pores and hair follicles become clogged with sebum, an oily substance from skin glands. Acne is typically seen on the face but can also develop on the chest, shoulders, and upper back.
Types of Acne
- Comedogenic Acne (Non-inflammatory): Appears as whiteheads and blackheads.
- Non-comedogenic Acne (Inflammatory): Red, painful, and often pus-filled pimples.
Key Facts

- Gender: Affects both men and women, but is more common in women.
- Involved Area: Skin.
- Global Prevalence: 9.4% (as of 2015).
- Mimicking Conditions: Conditions like rosacea, folliculitis, and perioral dermatitis can resemble acne.
Diagnostic Tests
- Hormonal evaluations: Luteinizing Hormone, Follicle-Stimulating Hormone, and Dehydroepiandrosterone (DHEA) tests may be needed.
Treatment Options
- Retinoids: Retinoic acid, Tretinoin, Adapalene.
- Antimicrobials: Azelaic acid.
- Topical Antibiotics: Clindamycin, Azithromycin.
- Anti-Acne Agents: Salicylic acid.
- Systemic Antibiotics: Doxycycline, Minocycline.
- Oral Treatment: Isotretinoin.
Symptoms of Acne
Acne manifests as clogged pores leading to pimples, blackheads, or skin nodes. Typical symptoms include:
- Red, painful skin around acne spots.
- Potential darkening or scarring over time.
- In rare, severe cases, symptoms may include fever and joint pain.
Types Based on Symptoms
- Comedogenic Acne:
- Whiteheads: Small, white lesions filled with sebum and dead cells.
- Blackheads: Dark bumps formed from open pores.
- Non-Comedogenic Acne:
- Papules: Small, painful bumps.
- Pustules: Red pimples with pus.
- Nodules: Large, solid pimples deep in the skin.
- Cysts: Deep, pus-filled, painful pimples that may scar.
Severe cases, known as nodulocystic acne, can cause larger, hardened masses, especially on the back and neck.
Common Causes of Acne
- Hormonal Changes
- Genetics
- Environmental Factors
- Lifestyle Factors
- Health Conditions
- Chemicals/Products
Treatment Options
Acne treatments include topical, systemic, and lifestyle approaches:
- Topical: Prescription creams or cleansers.
- Systemic: Antibiotics or hormonal therapies.
- Lifestyle: Diet changes, adequate hydration, and exercise. Proper treatment can help prevent future scarring.
General physicians, dermatologists, and gynecologists can help manage and treat acne effectively.
