Hyaluronic acid (HA, hyaluronan) is a glycosaminoglycan and a major component of the skin's extracellular matrix, where it can bind up to roughly 1,000 times its weight in water and is described as the key molecule controlling skin moisture. Its content and synthesis decline with age, contributing to reduced hydration and elasticity and to the appearance of fine lines. Applied topically in creams and serums, HA acts as a hygroscopic humectant that draws and holds water in the stratum corneum and superficial skin; low-molecular-weight HA penetrates more deeply, while high-molecular-weight HA forms a surface hydrating film—the rationale for multi-weight serums. It is widely used in cosmeceuticals for hydration and anti-aging.
Multiple randomized and controlled clinical studies of topical HA formulations report significant improvements in skin hydration and elasticity, with low-molecular-weight HA associated with reduced wrinkle depth; HA serums have also improved skin surface topography and measured HA content in treated skin. Oral HA now has several placebo-controlled randomized trials (and recent meta-analytic support) showing improved hydration, elasticity and wrinkle scores over 8-12 weeks, though most of these trials are small and industry-funded. However, effects on wrinkles are generally modest, most topical trials are short (weeks to a few months), many test HA combined with other active ingredients, and much of the improvement reflects surface hydration and plumping rather than structural rebuilding of the dermis. This evidence describes hyaluronic acid and its formulations in general, not this specific commercial serum.
Peer-reviewed studies on the active compound — citations link to PubMed.
“hyaluronic acid is well tolerated and effective for improving skin hydration and rejuvenation”
“application of hyaluronic acid to dry skin of elderly resulted in significant improvements in skin hydration”
“Topical application of all 0.1% HA formulations used in this study led to significant improvement in skin hydration and elasticity. Application of low-molecular-weight (LMW) HA was associated with significant reduction of wrinkle depth, which may be due to better penetration abilities of LMW HA.”
“Areas treated with RHA serum showed statistically significant improvements in skin surface topography and hydration compared to untreated areas.”
“Statistically-significant improvements in all facial skin attributes (weeks 4, 8, and 12), stratum corneum hydration (week 12), and transepidermal water loss (week 12) were observed.”
“The efficacy of the topical products is confirmed by subjective, clinical and instrumental assessment.”
