## What the research says

- A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase. ([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))
- Twice daily application of a multitargeted dermocosmetic cream provided comparable efficacy to benzoyl peroxide 5% gel in reducing inflammatory, non-inflammatory, and total lesions in 150 Caucasian subjects with mild-to-moderate acne over 56 days, while demonstrating superior skin tolerability. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/))
- The use of a salicylic acid-based dermocosmetic significantly reduces the needed quantity of benzoyl peroxide without impacting efficacy in mild to moderate acne, and as maintenance post-benzoyl peroxide allows a significant reduction of acne relapse compared to vehicle. ([Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38051857/))
- Daily application of hydrocolloid dressing completely prevented nasogastric tube-related pressure injuries, whereas skin care interventions showed no significant preventive effect compared to the control group in intensive care unit patients. ([Journal of Tissue Viability, 2024](https://pubmed.ncbi.nlm.nih.gov/39289093/))
- Hydration of scars for 2 months resulted in significantly reduced itching, somewhat reduced pain, and increased pliability by 10% for both hydrocolloid dressing and moisturizer treatments in patients with keloids or hypertrophic scars, with no change in physical parameters. ([Dermatologic Surgery, 1996](https://pubmed.ncbi.nlm.nih.gov/8874525/))
- Adjunctive hydrocolloid dressing with 0.1% mometasone furoate cream significantly increased treatment efficacy and cost-effectiveness compared to topical steroid alone in patients with moderate to severe lichen simplex chronicus. ([Skin Health and Disease, 2023](https://pubmed.ncbi.nlm.nih.gov/37538322/))

- Cross-linked carboxymethyl cellulose hydrogel provided excellent correction of facial defects, high tolerance, and absence of side effects or migration issues in 84 healthy volunteers. ([Clinical Interventions in Aging, 2010](https://pubmed.ncbi.nlm.nih.gov/21228896/))
- Polymeric bioadhesive microparticles composed of sodium carboxymethyl cellulose and Soluplus and loaded with 18beta-glycyrrhetinic acid form an in situ hydrogel upon contact with wound exudate, enabling controlled drug release that stimulates keratinocyte growth. ([International Journal of Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33862131/))
- Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients. ([CMAJ, 2010](https://pubmed.ncbi.nlm.nih.gov/20837684/))
