Why Some People Get More Pimples and Acne: Demographics, Causes, and the Role of Mollenol
2nd Sep 2025
Gender and Age Demographics
Acne affects approximately 650 million people worldwide and impacts both men and women, but with distinct patterns across different age groups. The distribution shows significant gender and age-related variations:[1]
Teenage Acne (12-25 years)
Acne predominantly affects 85% of young adults aged 12-25 years. In Taiwan, the highest prevalence occurs in children aged 7-12 years at 14.39%, with girls in this age group showing a prevalence rate of 17.78%. During adolescence, up to 93% of teenagers aged 16-18 years experience acne.[2][3][4][5][6][1]
Adult Acne (25+ years)
The pattern shifts dramatically in adulthood. Adult acne affects significantly more women than men, with a female-to-male ratio of approximately 1.81:1. Studies show that 50.9% of women aged 20-29 years have acne, compared to 35.2% of women aged 30-39 years. Among adults seeking acne treatment, women comprise 65.2% of visits.[7][8][4]
Adult female acne demonstrates clear patterns: 45% of women aged 21-30, 26% aged 31-40, and 12% aged 41-50 experience clinical acne. The condition is categorized into two main types: persistent acne (continuing from adolescence, affecting 75-85% of adult female cases) and late-onset acne (developing after age 25, affecting 20-40% of cases).[8][9]
Main Causes: Why Some People Get More Acne
Genetic Factors
Family history represents one of the strongest risk factors for acne development. Research indicates that 81% of acne variants are caused by genetics and family history. If both parents had acne, their child has a 25% chance of developing severe acne. Studies show that 57.1% of people with acne have a family history of the condition, and genetics play a role in around 80-90% of acne cases.[10][11][12]
Hormonal Mechanisms
Testosterone and other androgens are primary drivers of acne development. During puberty, increased androgen levels cause sebaceous glands to enlarge and produce excessive sebum. This process involves several key steps:[13][14][15][16]
- Testosterone stimulates sebum production in sebaceous glands[15]
- Type I 5-alpha reductase converts testosterone to dihydrotestosterone (DHT), which has greater affinity for sebaceous gland receptors[16]
- Androgens promote both sebaceous gland growth and secretory function[16]
Women may experience acne flare-ups due to hormonal fluctuations during menstruation, pregnancy, and menopause. Research shows 72% of women with acne have excess androgen hormones, and 62.2% of premenopausal women report worsening acne around menstruation.[17][18][8][15]
Four Core Pathogenic Mechanisms
Modern research identifies four interlocking pathogenic pillars of acne development:[19]
- Hyper-seborrhea (excessive oil production)
- Hyper-keratinization (abnormal skin cell shedding)
- Bacterial overgrowth (particularly Cutibacterium acnes)
- Inflammation (immune system response)
Additional Risk Factors
Environmental and lifestyle factors also contribute to acne susceptibility:
- Dietary factors: High glycemic foods, dairy products, and excessive fats may worsen acne[20][10]
- Stress: Can exacerbate existing acne through hormonal pathways[21][20]
- Smoking: Associated with increased acne risk[10]
- Cosmetic use: Improper product selection may contribute to pore blockage[1]
Mollenol: Natural Antimicrobial Treatment for Acne
Mollenol is an over-the-counter topical treatment registered with Australia's Therapeutic Goods Administration (AUST L 235288) that targets multiple aspects of acne pathogenesis through natural antimicrobial compounds.[22][19]
Active Ingredients and Mechanisms
Mollenol harnesses four primary botanical antimicrobials that work synergistically to address acne:[19][22]
Clove Bud Oil (Eugenol and Acetyl Eugenol): The primary active component, with eugenol comprising 71-90% of clove oil. Research demonstrates eugenol achieves a minimum inhibitory concentration (MIC) of 0.31 mg/mL against Cutibacterium acnes. The compound provides COX-2 inhibition for anti-inflammatory activity while offering mild local anesthetic effects.[22][19]
Coconut-Derived Lauric Acid: This medium-chain fatty acid shows selective antimicrobial action against Gram-positive bacteria with an MIC of 1.95 µg/mL against C. acnes - making it approximately 15 times stronger than benzoyl peroxide. Lauric acid also strengthens the skin's lipid barrier while penetrating efficiently due to its molecular structure.[19][22]
Tea Tree Oil (Terpinen-4-ol): Provides bactericidal, anti-inflammatory, and antioxidant properties. Clinical trials show 5% tea tree oil gel reduced total acne lesion counts and severity 3-6 times more effectively than placebo over 45 days.[22][19]
Sandalwood Oil: Contributes anti-inflammatory and wound-healing sesquiterpenes for additional therapeutic support.[22]
Multi-Layer Skin Penetration
Mollenol's formulation leverages penetration enhancement properties of its essential oil components. Clove oil achieves an enhancement ratio (ER) of 2.63 for drug penetration, significantly outperforming synthetic enhancers. The mechanism involves temporary disruption of stratum corneum lipid structure rather than permanent damage, creating channels for active ingredient delivery.[22]
Clinical Application and Benefits
Mollenol targets all four pathogenic pillars of acne development simultaneously:[19]
- Antimicrobial action: All primary components demonstrate proven efficacy against acnes
- Anti-inflammatory effects: Multiple compounds contribute inflammation reduction
- Barrier support: Lauric acid specifically strengthens skin barrier function
- Enhanced penetration: Essential oil components facilitate deeper active delivery
Users report faster "head-softening," reduced redness, and accelerated pustule drying within several days of application. The treatment is available as full-strength and "Sensitive" lotions plus hydrocolloid patches for comprehensive acne management.[23][24][19]
Safety Profile
Mollenol contains no artificial substances, parabens, or animal products. However, it should not be applied during pregnancy or breastfeeding, or within 1cm of the eyes. While generally safe, some users may experience mild skin irritation or allergic reactions due to individual sensitivities to essential oils.[25][23]
Mollenol represents a natural antimicrobial alternative that addresses bacterial proliferation, inflammation, and barrier dysfunction with reduced risk of bacterial resistance compared to conventional antibiotic treatments. The formulation's evidence-based selection of botanical compounds provides antimicrobial efficacy that individually matches or outperforms standard topical agents in laboratory studies.[19][22]
