- How deep it getsHuman skin penetration of hyaluronic acid of different molecular weights as probed by Raman spectroscopy
Hyaluronic acid of 20-300 kDa crossed the stratum corneum in excised human skin, while hyaluronic acid of 1000-1400 kDa remained in the stratum corneum.
In vitro study · 2016 · Excised human skin sections · Excised human skin with intact stratum corneum, measured by Raman micro-imaging after topical application. · One laboratory's imaging study. Three molecular-weight grades were tested. "remains above" describes intact stratum corneum in this ex vivo setup.
- How deep it getsFifty-kDa hyaluronic acid upregulates some epidermal genes without changing TNF-α expression in reconstituted epidermis
In reconstituted human epidermis, hyaluronic acid of about 50 kDa penetrated better than the larger grades and increased expression of genes and proteins involved in tight-junction formation and keratinocyte cohesion; its TNF-α expression stayed close from the 20 kDa grade.
In vitro study · 2011 · Reconstituted human epidermis (in vitro) · Reconstituted human epidermis incubated with hyaluronic acid of 20, 50, 130, 300, 800 and 1500 kDa. · The material tested is a defined ~50 kDa grade.
- Skin effectEfficacy of cream-based novel formulations of hyaluronic acid of different molecular weights in anti-wrinkle treatment
All five 0.1% hyaluronic acid creams tested, from 50 kDa to 2000 kDa, raised skin hydration and overall elasticity above the vehicle cream applied to the other eye at 60 days.
Human trial · 2011 · 76 people · Women aged 30-60 with periocular wrinkles · 0.1% hyaluronic acid creams applied twice daily for 60 days to the eye area of women aged 30-60 with periocular wrinkles. · Sixty days, and the vehicle sat on the fellow eye. Hydration and elasticity were read by instruments. The volunteers were women aged 30-60 with eye-area wrinkles.
- Skin effectEfficacy of a New Topical Nano-hyaluronic Acid in Humans
Eight weeks of a low-molecular-weight "nano" hyaluronic acid lotion, serum and cream reduced measured periorbital wrinkle depth by up to 40% and raised corneometer hydration by up to 96%.
Human trial · 2014 · 33 people · Women with a mean age of 45.2 years · A three-step regimen (lotion, serum, cream) built on a low-molecular-weight hyaluronic acid, used for eight weeks on women with a mean age of 45.2. · The percentages are within-group changes. 33 participants in one centre, and the material is described as "nano" hyaluronic acid.
