In lab tests, the liposomal form of hyaluronic acid helps skin’s deeper layer cells make more of the structural proteins that keep skin firm and strong.
Scientific Claim
Liposomal hyaluronic acid (LPS-HA) is associated with a 138.4% increase in type I collagen expression and a 133.6% increase in type III collagen expression in human fibroblasts, compared to untreated controls, suggesting potential support for dermal matrix integrity.
Original Statement
“In fibroblasts, LPS-HA increased the expression of type I and type III collagens (138.4 and 133.6%) without increasing that of elastin (68.3–94.7%) and reduced UVB-induced IL-6 (79.1–90.2% of UVB; p<0.05).”

Assessment Explanation
The in vitro fibroblast model demonstrates association between LPS-HA and increased collagen mRNA, but cannot prove this translates to increased collagen deposition in living human skin. 'Associated with' is appropriate.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Randomized Controlled TrialLevel 1bWhether topical LPS-HA increases dermal collagen content in living human skin over time.
Whether topical LPS-HA increases dermal collagen content in living human skin over time.
What This Would Prove
Whether topical LPS-HA increases dermal collagen content in living human skin over time.
Ideal Study Design
A double-blind RCT with 80+ adults aged 35–60 applying LPS-HA (1%) or vehicle daily for 12 weeks, with skin biopsies at baseline and endpoint analyzed for type I/III collagen via immunohistochemistry and hydroxyproline assay.
Limitation: Biopsies are invasive and may not capture long-term remodeling.
Prospective Cohort StudyLevel 2bWhether long-term LPS-HA use correlates with improved skin elasticity and collagen density.
Whether long-term LPS-HA use correlates with improved skin elasticity and collagen density.
What This Would Prove
Whether long-term LPS-HA use correlates with improved skin elasticity and collagen density.
Ideal Study Design
A 6-month cohort study of 150+ individuals using LPS-HA daily vs. non-users, with monthly elastometry (Cutometer) and quarterly skin ultrasound to assess dermal echogenicity and collagen fiber density.
Limitation: Cannot isolate LPS-HA effect from other lifestyle or product factors.
In Vitro Fibroblast StudyLevel 5In EvidenceWhether LPS-HA directly upregulates collagen gene expression in human dermal fibroblasts.
Whether LPS-HA directly upregulates collagen gene expression in human dermal fibroblasts.
What This Would Prove
Whether LPS-HA directly upregulates collagen gene expression in human dermal fibroblasts.
Ideal Study Design
A replicated study using primary human dermal fibroblasts treated with LPS-HA (0.1–1%) vs. HA (0.1–1%) for 24–72h, measuring COL1A1 and COL3A1 mRNA via qPCR and collagen protein via ELISA and Western blot.
Limitation: Does not reflect skin architecture, mechanical stress, or immune interactions.
Animal Model StudyLevel 4Whether LPS-HA increases dermal collagen in a living mammalian model.
Whether LPS-HA increases dermal collagen in a living mammalian model.
What This Would Prove
Whether LPS-HA increases dermal collagen in a living mammalian model.
Ideal Study Design
A study in 40+ aged mice treated topically with LPS-HA or HA daily for 8 weeks, with skin biopsies analyzed for collagen content (Masson’s trichrome), dermal thickness, and hydroxyproline levels.
Limitation: Mouse skin aging and collagen metabolism differ from humans.
Cross-Sectional StudyLevel 3Whether users of LPS-HA products have higher dermal collagen density than non-users.
Whether users of LPS-HA products have higher dermal collagen density than non-users.
What This Would Prove
Whether users of LPS-HA products have higher dermal collagen density than non-users.
Ideal Study Design
A study comparing dermal collagen density via dermal ultrasound or biopsy in 50+ long-term LPS-HA users vs. 50+ non-users, matched for age, sun exposure, and skin type.
Limitation: Cannot determine if LPS-HA caused the difference or if users have inherently healthier skin.

The study found that this special form of hyaluronic acid, when applied to skin cells, made them produce way more of the two key proteins (collagen) that keep skin firm and healthy — just like the claim said.
