|---|---|---|---|---|
| Zinc Acne Meta-Analysis | National Institute for Health and Care Excellence (NICE) guidelines recommend azelaic acid in combination with oral antibiotics for moderate-to-severe acne or as a second-line monotherapy option if adapalene/BPO combinations are not tolerated. | 3 | Searle Tamara N (2026) | Cosmeceuticals in acne vulgaris: from mechanism of action to clinical application |
| Zinc Acne Meta-Analysis | Stronger clinical support exists for the use of retinol, BPO and azelaic acid, while other cosmeceuticals such as niacinamide, zinc, tea tree oil and green tea could be promising adjuncts, although there is less robust evidence to support their use. | 3 | Searle Tamara N (2026) | Cosmeceuticals in acne vulgaris: from mechanism of action to clinical application |
| Zinc Acne Meta-Analysis | Many current studies use formulations with multiple ingredients, making the assessment of individual component efficacy challenging; larger randomized controlled trials (RCTs) with standardized outcome measures are required, and most research is based on mild-to-moderate acne, demonstrating a gap in the clinical evidence for studies on the use of cosmeceuticals in more severe acne. | 3 | Searle Tamara N (2026) | Cosmeceuticals in acne vulgaris: from mechanism of action to clinical application |
| Zinc Acne Meta-Analysis | acnes Melaleuca arternifolia C. acnes 1 2 Cosmeceuticals are topical treatments with biologically active properties that may provide therapeutic effects without the requirement for a doctor’s prescription. | 3 | Searle Tamara N (2026) | Cosmeceuticals in acne vulgaris: from mechanism of action to clinical application |
| Zinc Acne Meta-Analysis | These treatments show varying degrees of efficacy and improved safety profiles, but most lack head-to-head comparisons with isotretinoin. | 4 | Tommasino N (2026) | Beyond Isotretinoin: A Narrative Review of Emerging Systemic Therapies for Moderate-to-Severe Acne. |
| Zinc Acne Meta-Analysis | Conclusion Several systemic options beyond isotretinoin have emerged, showing potential in specific subgroups or as adjunctive therapies. | 4 | Tommasino N (2026) | Beyond Isotretinoin: A Narrative Review of Emerging Systemic Therapies for Moderate-to-Severe Acne. |
| Zinc Acne Meta-Analysis | However, further large-scale comparative studies are needed to define their roles within evidence-based acne management algorithms. | 4 | Tommasino N (2026) | Beyond Isotretinoin: A Narrative Review of Emerging Systemic Therapies for Moderate-to-Severe Acne. |
| Zinc Acne Meta-Analysis | Background Acne vulgaris is a common inflammatory skin disorder with significant psychosocial impact. | 4 | Tommasino N (2026) | Beyond Isotretinoin: A Narrative Review of Emerging Systemic Therapies for Moderate-to-Severe Acne. |
