Acne is one of the most common skin conditions worldwide, affecting people of all ages with varying severity. This summary provides evidence-based home treatments for acne, their mechanisms of action, and practical applications to help effectively manage mild to moderate acne without prescription medications.

Understanding Acne Development

Acne develops through four primary factors:

• Excess sebum production: Often triggered by hormonal influences

• Follicular hyperkeratinization: Abnormal shedding of skin cells lining the follicle

• Bacterial colonization: Proliferation of Cutibacterium acnes (C. acnes)

• Inflammation: Immune response to bacterial overgrowth and follicular damage

Hormonal Influence: Androgens, particularly testosterone, stimulate sebaceous glands to produce excess sebum. This explains why acne commonly emerges during puberty but can occur throughout life due to hormonal fluctuations.

Risk Factors:

• Genetic predisposition

• High glycemic load diet

• Endocrine disorders

• Certain medications

• Stress

• Inappropriate skincare products

Evidence-Based Home Treatments

Topical Over-the-Counter Treatments

Benzoyl Peroxide

• Creates an oxygen-rich environment hostile to C. acnes

• Exfoliates and removes pore-clogging dead skin cells

• Reduces inflammation

• Available in 2.5% to 10% concentrations (lower strengths often equally effective with fewer side effects)

Salicylic Acid

• Penetrates oil-filled pores

• Dissolves intercellular cement holding dead skin cells together

• Particularly effective for comedonal (non-inflammatory) acne

• Recommended in concentrations from 0.5% to 2%

Azelaic Acid

• Possesses antimicrobial properties

• Reduces inflammation

• Normalizes follicular keratinization

• May reduce post-inflammatory hyperpigmentation

Natural and Herbal Remedies

Tea Tree Oil

• Demonstrated efficacy against mild to moderate acne

• Application method: Mix 1 part tea tree oil with 9 parts water, apply to affected areas 1-2 times daily

Honey

• Offers antibacterial and anti-inflammatory properties

• Application method: Apply raw, unpasteurized honey to clean skin for 10-15 minutes, then rinse

Green Tea

• Contains catechins with antioxidant and anti-inflammatory effects

• Benefits from both drinking and topical application

• Application method: Apply cooled green tea with a cotton ball, let dry, then rinse

Plant Extracts

• Garcinia mangostana (mangosteen)

• Myrtus communis (myrtle)

• Rosa (rose) extract

Dietary Approaches

Low Glycemic Index Diet

• Multiple studies link high glycemic load diets to acne severity

• Foods to favor: Whole grains, legumes, most fruits and vegetables, nuts and seeds

• Foods to limit: White bread, refined cereals, sugary drinks and sweets, white potatoes and rice

Dairy Consideration

• Some studies link dairy consumption, particularly skim milk, with acne

• Consider reducing intake and monitoring results if you notice a correlation

Zinc Supplementation

• May reduce acne severity due to anti-inflammatory properties

• Daily supplement of 30-45 mg of elemental zinc may be beneficial (consult healthcare provider)
