Questions and answers

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

• 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

• 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

• 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

• Treatment with 2% supramolecular salicylic acid hydrogel resulted in a regression and markedly improvement rate of 51.01% compared to 43.10% for Adapaline gel in patients with mild to moderate facial acne vulgaris, showing no significant difference in efficacy.

  Journal of Cosmetic Dermatology, 2024

• Topical 5% benzoyl peroxide plus salicylic acid achieved the greatest lesion reduction at early 2 to 4 week time points compared to benzoyl peroxide, clindamycin, and combination benzoyl peroxide/clindamycin, while 5% benzoyl peroxide plus salicylic acid and combination benzoyl peroxide/clindamycin showed similar efficacy at 10 to 12 weeks in acne patients.

  Journal of the American Academy of Dermatology, 2010

• Combining 755 nm alexandrite laser with topical licorice gel significantly reduces terminal hair counts compared to alexandrite laser with placebo in women with idiopathic hirsutism.

  Evidence-based Complementary and Alternative Medicine, 2015

• Licochalcone A activated Nrf2 signaling, elevated cytoprotective enzymes, increased the reduced-to-oxidized glutathione ratio, and decreased reactive oxygen species in human fibroblasts and neutrophils, while a LicA-rich licorice extract lowered UVA-induced oxidative processes in vivo.

  Experimental Dermatology, 2015

• Bioactive glycyrrhizic acid and oxymatrine ionic liquid self-assembled nanomicelles significantly promoted the transdermal permeation, subcutaneous retention, and anti-photoaging efficacy of palmitoyl pentapeptide-4 in cellular and animal models compared to unformulated peptide.

  Advanced Science, 2025

• Thymoquinone-loaded liposomal chitosan gel demonstrated superior in vivo anti-inflammatory activity over thymoquinone gel and a comparable effect to marketed indomethacin gel in rats with carrageenan-induced paw edema.

  AAPS PharmSciTech, 2018

• Thymoquinone pre-treatment attenuated UVA-induced oxidative stress, inflammation, and mitochondrial apoptosis in human HaCaT keratinocytes through COX-2 inhibition via the activation of the NrF2/ARE pathway.

  Molecular Immunology, 2021

• Topical application of thymoquinone treated with cold plasma significantly improved wound healing potential, augmenting skin regeneration indices, reducing tumor necrosis factor-alpha, and enhancing hyaluronic acid, collagen type I, interleukin-10, alpha smooth muscle actin, and vascular endothelial growth factor compared to thymoquinone alone in a rat wound model.

  International Immunopharmacology, 2023

• Silybum marianum flower extract increased human hair follicle dermal papilla cell proliferation and VEGF production while suppressing cellular senescence, and in a clinical study using hair shampoo, it significantly increased hair density and total hair count at 16 and 24 weeks compared with a placebo group.

  Journal of Cosmetic Dermatology, 2024

• Topical 0.5% silymarin-loaded antioxidant serum applied twice daily significantly reduced clinical acne severity, lesion counts, and melanin pigmentation in 22 Korean acne patients over 4 weeks without associated adverse events.

  Journal of Cosmetic Dermatology, 2023

• Topical silymarin cream 1.4% showed comparable results to salicylic acid 30% peels in reducing acne severity in 30 patients with mild to moderate acne vulgaris.
