Questions and answers

What the research says

• Both oral and topical collagen supplements help delay the skin aging process by improving moisture, elasticity, and hydration, with no differences arising between the two types of collagen.

  Dermatology Practical & Conceptual, 2022

• The use of cosmetic products containing collagen or its peptides improves the general condition of the skin, reduces wrinkle depth, improves hydration and density, reduces transepithelial water loss, and delays the aging process, while oral bioactive collagen peptides also reduce nail breakage.

  Current Issues in Molecular Biology, 2024

• 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 0.4% retinol significantly increased epidermal thickness, dermal vascularity, and extracellular matrix production by stimulating keratinocyte proliferation, endothelial cell proliferation, and fibroblast activation in naturally aged human skin compared to vehicle.

  International Journal of Cosmetic Science, 2017

• Topical bakuchiol 0.5% applied twice daily compared with retinol 0.5% applied daily significantly decreased wrinkle surface area and hyperpigmentation with no statistical difference between the compounds in 44 patients over 12 weeks, while retinol users reported more facial skin scaling and stinging.

  The British Journal of Dermatology, 2019

• Silicone particles encapsulating retinol increased its half-life by 9-fold and yielded 12-23% lower skin irritation in human subjects compared to Microsponge particles while maintaining biological activity.

  Journal of Controlled Release, 2018

• 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

• Combined probiotic supplementation and topical azelaic acid with hydroxypinacolone retinoate reduced non-inflammatory lesions from 11.5 to 7.3 and decreased microscopic acne features measured by reflectance confocal microscopy and dynamic optical coherence tomography in 20 patients over 12 weeks.

  Journal of Clinical Medicine, 2023

• 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

• Topical application of TAC/Collagen postbiotics gel improved skin moisture score and inflammation index, and reduced porphyrins and brown spots in 20 volunteers with acne vulgaris.

  Journal of Cosmetic Dermatology, 2022

• Topical collagen tripeptide application improved skin wrinkles, elasticity, and density while reducing advanced glycated end products in 22 Asian women over 4 weeks.

  International Journal of Molecular Sciences, 2022

• Marine collagen extracted from Greenland halibut skin showed a non-cytotoxic effect on fibroblast cells and provided a slight skin hydration effect when incorporated into cosmetic hydrogel formulations at dosages of 0.1, 0.25, and 0.5% in 23 healthy volunteers.

  Marine Drugs, 2023

• 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

• Squalane at 0.005-0.015% counteracts UVA-induced oxidative stress, inflammation, and collagen metabolism inhibition while stimulating fibroblast migration in human dermal fibroblasts.

  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

Why other serums fit acne-prone skin better

• 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 nicotinamide plus an antibacterial adhesive agent and zinc-pyrrolidone carboxylic acid combined with adapalene significantly reduced noninflammatory acne lesions by the second week of therapy compared to placebo with adapalene in patients with moderate acne vulgaris.

  The Journal of Clinical and Aesthetic Dermatology, 2020

• 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.
