  Molecules, 2025

• Plant-derived squalane protected human dermal fibroblasts against UVA-induced damage by counteracting ROS formation, suppressing apoptosis-related proteins p53, caspase-3, caspase-9, and PARP, and restoring the pro-survival p-Akt/mTOR pathway.

  Antioxidants, 2025

• 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.

  Journal of Cosmetic Dermatology, 2019

• A topical serum containing hydroxypinacolone retinoate and peptides used twice daily for 16 weeks achieved parity or statistically significantly better improvement in facial aging parameters compared to a single fractional CO2 laser treatment in women with moderate global photodamage.

  Journal of Cosmetic Dermatology, 2025

• Hydroxypinacolone retinoate and retinyl propionate at a 5:9 weight ratio synergistically enhanced antiaging gene expressions in vitro and improved skin wrinkles, smoothness, transepidermal water loss, and elasticity in 42 Chinese urban women over an 8-week period without adverse reactions compared to retinol.

  Journal of Cosmetic Dermatology, 2023

• A new topical gel formulation reduced total acne lesions by 80% and GAGS scores by 78% after 8 weeks in 22 female patients with mild facial acne without impairing skin barrier function or causing side effects.

  Giornale Italiano Di Dermatologia E Venereologia, 2020

• Topical beta-carotene provided protection for the human skin of healthy volunteers against IR radiation by acting as a superficial antioxidant, though dermal carotenoid degradation was significantly higher for standard infrared radiator than for water filter infrared irradiation.

  Experimental Dermatology, 2011

• Pre-treatment with beta-carotene at 1.5 microM modulated UVA-induced gene regulation in HaCaT human keratinocytes through multiple mechanisms not restricted to singlet oxygen quenching, reducing the effect for 143 genes and enhancing it for 180 out of 568 UVA-regulated genes.

  The Journal of Investigative Dermatology, 2005

• Alginate hydrogel dressings co-loaded with cinnamon-mediated silver nanoparticles, beta-carotene nanocarriers, and Centella asiatica extract demonstrated antimicrobial and antibiofilm activities against Staphylococcus aureus and Escherichia coli over a 24-h period while mitigating silver-induced cytotoxicity and oxidative stress in human keratinocyte cells.

  Gels, 2025

Why other serums fit oily acne-prone skin better

• Niacinamide and ferulic acid incorporated in a stable multiple emulsion successfully reduced melanin, sebum, and skin erythema while improving skin elasticity and hydration in human skin compared to a placebo.
