Quality attributes of partially hydrolyzed collagen in a liquid formulation used for skin care.
Article in Journal of cosmetic dermatology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe deterioration of the skin accentuates over time, affecting its aesthetic appearance. This is characterized by the weakening of the mechanisms involved in the regeneration and repair of the dermal matrix. Consequently, the skin losses elasticity and smoothness resulting in the formation of wrinkles. The alternatives for facial rejuvenation include surgery, injection of botulinum toxin, and the application of masks. Topic products are less invasive, can be self-applied, and have an increased benefit/risk relationship.
aimWe developed a liquid formulation containing collagen hydrolyzed and evaluated the product by cutting-edge technology in order to define proper its quality attributes.
methodsWe employed nuclear magnetic resonance (NMR), size-exclusion chromatography (SEC), and mass spectrometry (MS). Additionally, we analyzed its cosmetical effect in five volunteers and we demonstrate the product safety.
resultsOur results demonstrate the following: (a) a stable secondary structure identity associated to the known triple helix arrangement in liquid and solid states; (b) a typical conformational flexibility depending on its hydration state; (c) thermal stability confirmed by liquid- and solid-state nuclear magnetic resonance schemes; and (d) a molecular mass distribution of peptides between 0.5 and 19.5 kDa. The product faded wrinkles in the forehead, an effect that remained after removing the mask. The formula was non-irritating and hypoallergenic.
conclusionWe characterized, using state-of-the-art methodologies, the quality attributes that are critical for the safety and beneficial effect of a new collagen-containing formula.
