Questions and answers

What the research says

• 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 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

• Cosmetic formulations containing 5% Centella asiatica extract showed the best efficacy in improving skin moisture and decreasing transepidermal water loss, while also exhibiting antiinflammatory properties in 25 volunteers compared to baseline measurements.

  Indian Journal of Pharmaceutical Sciences, 2016

• Co-delivery of paeonol and madecassoside via nanoemulsions improved transdermal delivery, promoted barrier repair proteins, inhibited inflammatory cytokine secretion in cellular and 3D models, and reduced transepidermal water loss and acne in human facial skin compared to free components.

  Molecules, 2023

• Chitosan-based hydrogels loaded with asiaticoside-rich Centella asiatica extract achieved controlled drug release, skin permeability, antimicrobial activity, and synergistic wound healing effects in an in vitro model.

  International Journal of Molecular Sciences, 2023

• Centella asiatica extract significantly decreased markers of cell death, oxidative stress, cellular senescence, and apoptosis in hydrogen peroxide-induced human epidermal keratinocytes compared to cells treated with hydrogen peroxide alone.

  Biology, 2025

• A topical spray containing Centella asiatica extract was non-irritating and achieved complete wound healing after 14 days in an excision wound rat model.

  Acta Pharmaceutica, 2016

• Topical 0.5% hyaluronic-ZnO nanogel applied twice daily reduced inflammatory-lesion counts by 58% at week four in human subjects compared to baseline without causing erythema.

  Biomedicines, 2025

• Nels cream achieved a similar reduction in inflammatory and noninflammatory lesion counts compared to 5% benzoyl peroxide in acne vulgaris patients, but caused significantly fewer side-effects such as peeling and dryness.

  Clinical and Experimental Dermatology, 2000

• Topically applied coated and uncoated zinc oxide nanoparticles under flexing and massage are retained in the stratum corneum with no significant penetration into the viable epidermis and no cellular toxicity in human skin.

  Nanomedicine, 2016

• 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 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 application of 0.05% w/w ECa 233 gel reduced erythema index by 0.03 U and improved early crusting and general wound appearance compared to placebo in thirty individuals undergoing facial laser resurfacing.

  Journal of Alternative and Complementary Medicine, 2020

• 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

• Moisturizer containing 5% panthenol, madecassoside, and copper-zinc-manganese decreased adverse reactions and downtime after ablative fractional carbon dioxide laser resurfacing with comparable efficacy to 0.02% triamcinolone acetonide cream in 20 subjects.
