A fixed-dose combination topical gel for acne vulgaris, combining a third-generation synthetic retinoid (Adapalene) with a potent antimicrobial and comedolytic agent (Benzoyl Peroxide). This combination targets multiple pathogenic factors of acne: abnormal follicular keratinization, inflammation, and Cutibacterium acnes proliferation. It is considered a first-line treatment for mild to moderate inflammatory and non-inflammatory acne.
Adult: Apply a thin film once daily, in the evening, to clean, dry affected areas of the face and/or trunk.
Note: 1. Wash face with a mild, non-medicated cleanser and pat dry. 2. Dispense a pea-sized amount for the entire face. 3. Apply a thin layer, avoiding eyes, lips, nostrils, and mucous membranes. 4. Do not apply to broken, sunburned, or eczematous skin. 5. Wash hands after application. 6. Use a non-comedogenic moisturizer to manage dryness. 7. Daily use of a broad-spectrum sunscreen (SPF 30 or higher) is MANDATORY due to increased photosensitivity.
The combination exerts synergistic effects by targeting multiple pathways in acne pathogenesis. Adapalene normalizes follicular keratinization and reduces microcomedone formation by modulating keratinocyte differentiation and proliferation via specific retinoic acid receptors (RAR-β and RAR-γ). Benzoyl Peroxide exerts potent bactericidal activity against C. acnes through the release of free oxygen radicals, reduces sebum free fatty acids, and has mild comedolytic and anti-inflammatory properties.
Pregnancy: Category C. Adapalene is teratogenic in animals at high oral doses. Topical systemic absorption is minimal, but use is contraindicated due to potential risk. A negative pregnancy test is advised before initiation in women of childbearing potential. Effective contraception is recommended.
Driving: No effect. However, if product accidentally gets into eyes, it can cause temporary blurring of vision affecting driving ability.
