Questions and answers

What the research says

• A hyperoside-enriched fraction of Houttuynia cordata Thunb. inhibited UVB-induced oxidative stress, inflammation, and collagen degradation in human dermal fibroblasts by regulating the MAPK signaling pathway.

  Plants, 2021

• Houttuynia cordata extract containing hyperoside and quercitrin protected human HaCaT keratinocytes from UVB-induced cell damage, apoptosis, oxidative stress, and inflammation by modulating MAPKs and Akt signaling pathways.

  Antioxidants, 2022

• Fermented Houttuynia cordata extracts reduced oxidative stress, inflammation factors, and inflammatory gene expression while increasing keratin-1 gene expression in H2O2 and UVA-treated human skin keratinocytes more effectively than unfermented extracts.

  Applied Biochemistry and Biotechnology, 2023

• A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2017

• Treatment with a rose extract activated newly identified skin olfactory receptors and prevented epinephrine-induced skin stress responses in epidermal keratinocytes and human skin explants, while clinically decreasing the appearance of under-eye dark circles in stressed women.

  Molecules, 2020

• Rose petal extract improves stratum corneum moisture levels in humans by upregulating HAS2 expression via the GLK-MAP2K-MAPK signaling pathway.

  BioFactors, 2023

• Rosa gallica petal extract (RPE) exerts skin whitening by attenuating tyrosinase activity and melanin accumulation and exhibits anti-wrinkle activity by suppressing MMP-1 levels in human cells.

  Journal of Medicinal Food, 2020

• Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.

  Journal of Drugs in Dermatology, 2011

• Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

  Clinical Oral Investigations, 2022

• Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days.

  BMC Oral Health, 2019

• Topical moisturizers improved skin barrier function and surface moisture, while a postbiotic moisturizer with yeast extract uniquely supported microbiome balance and modulated biomarkers of skin barrier, structure, and inflammation in participants and ex vivo explants exposed to environmental aggressors.

  Journal of Clinical Medicine, 2023

• A maintenance therapy with a cosmeceutical formulation containing hydroxyphenoxy propionic acid, ellagic acid, yeast extract, and salicylic acid over 20 weeks significantly improved even skin tone, spot intensity, spot size, and overall hyperpigmentation in 33 healthy subjects with moderate facial dyspigmentation.

  Journal of Drugs in Dermatology, 2015

• A methanol yeast extract increases proliferation and migration while decreasing entrance into senescence and apoptosis phases in 3T3 fibroblast cells.

  Journal of Cosmetic Science, 2014

• Topically delivered gold-coated silica microparticles combined with laser pulses reduced inflammatory lesions compared with sham treatments in patients with moderate-to-severe facial acne.

  The Journal of Investigative Dermatology, 2015

• Laser-activated gold microparticles combined with topical retinoids reduced inflammatory lesion counts by 68% at month 12 in 52 patients with mild-to-moderate inflammatory facial acne.

  Journal of Drugs in Dermatology, 2023

• Combined treatment with a micro-diamond and micro-gold topical serum and a 1064 nm picosecond Nd:YAG laser produced moderate clinical improvement and high participant satisfaction in 40% of participants for facial skin rejuvenation with minimal side effects.

  Dermatologic Therapy, 2022

• Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups.

  Military Medicine, 2024

• Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms.

  Clinical and Experimental Dermatology, 2007

• Externally applied substances such as ceramides, hyaluronic acid, licorice extracts, dimethicone, petrolatum, and paraffin wax treat skin disease resulting from damage to the skin barrier.
