Questions and answers

What the research says

• Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.

  The British Journal of Dermatology, 2002

• Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin.

  Journal of Cosmetic Dermatology, 2021

• Topical treatment of nicotinamide, alone or in combination with other active ingredients, reduces the progression of skin aging and hyperpigmentation in clinical trials while being well tolerated.

  Antioxidants, 2021

• Topical application of micronised titanium dioxide results in no dermal absorption, with the particles being deposited solely on the outermost surface of the stratum corneum.

  Skin Pharmacology and Applied Skin Physiology, 2001

• Microfine titanium dioxide does not penetrate human skin when formulated in an oil-in-water emulsion with the pigment dispersed in the aqueous phase, compared to oily dispersions and liposomal encapsulation which allow deeper skin penetration.

  International Journal of Cosmetic Science, 2000

• Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women.

  The Journal of Investigative Dermatology, 2008

• Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging.

  Dermatologic Surgery, 2005

• Topical 2% niacinamide significantly decreased sebum excretion rate in Japanese individuals and casual sebum levels in Caucasian individuals compared to placebo or baseline.

  Journal of Cosmetic and Laser Therapy, 2006

• Cherry blossom extract reduced nitric oxide production by 31.83% in vitro and decreased visual scores and erythema values compared to placebo in volunteers with sodium lauryl sulphate-induced skin irritation.

  International Journal of Cosmetic Science, 2014

• Cherry blossom extract at 1, 10, and 100 μg mL-1 increased type-I procollagen in UVB-irradiated normal human dermal fibroblasts by downregulating MAPK/AP-1 to reduce MMP-1 and MMP-3, upregulating TGF-βI/Smad, and facilitating Nrf2/ARE nuclear translocation.

  Photochemistry and Photobiology, 2018

• Cherry blossom extract protects HaCaT cells from UVB-induced oxidative stress and apoptosis by reducing reactive oxygen species, malondialdehyde, DNA damage, and pro-apoptotic protein expression while increasing antioxidant enzyme activities and Bcl-2 expression.

  Cytotechnology, 2019

• A cream combining propolis, tea tree oil, and Aloe vera reduced erythema scars, acne severity index, and total lesion count better than erythromycin cream in sixty patients with mild to moderate acne vulgaris compared to placebo.

  Clinical Pharmacology, 2018

• Topical aloe vera gel significantly accelerated split-thickness skin graft donor-site healing compared to placebo in 12 patients, but showed no significant difference in pain relief.

  Plastic and Reconstructive Surgery, 2018

• Topical application of Aloe vera cream reduced postoperative pain at rest and during defecation, accelerated wound healing at two weeks, and decreased analgesic requirements in patients after open hemorrhoidectomy compared to placebo.

  Journal of Alternative and Complementary Medicine, 2010

• Replacing microsized titanium dioxide and zinc oxide with nanoparticles in sunscreens eliminates opaqueness and alters UV protection balance while inducing (photo)cyto- and genotoxicity and penetrating viable skin layers during long-term exposures.

  Nanotechnology, Science and Applications, 2011

• Microfine zinc oxide and titanium dioxide do not penetrate the stratum corneum of porcine skin in vitro, indicating that their use in sunscreens does not pose a health risk from internal exposure.

  Toxicology in Vitro, 2006

• Hyaluronic acid-grafted titanium dioxide nanoparticles increased SPF from 13.3 to 19.1 while demonstrating low photocatalytic activity, exceptional thermal stability with >95% SPF retention, enhanced moisturization with >80% hydration retention, and minimal cytotoxicity with 88.5% cell viability in HaCaT keratinocytes compared to unmodified nanoparticles.

  International Journal of Biological Macromolecules, 2025

• Curcumin-loaded polyglutamic acid and gum arabic electrospun nanofibers accelerated wound healing, increased TGF-beta1 and VEGF expression, reduced inflammatory factors, and enhanced re-epithelialization and tissue regeneration in a mouse model with acute full-thickness skin defects.

  International Journal of Biological Macromolecules, 2024

• Polyglutamic acid and polylysine composite hydrogels promote wound repair and hemostasis through high water absorption, bioadhesion, calcium ion-mediated coagulation factor activation, and inherent antibacterial properties in a deep skin defect model.
