Signaling Molecules of Human Skin Cells as the Targets for Injection Cosmetology.
Article in Clinical, cosmetic and investigational dermatology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionSkin aging is a natural process that cannot be stopped. However, there are many ways to help attenuate premature aging of the skin and reduce the signs that have already appeared. One of them is the subcutaneous administration of preparations containing a combination of hyaluronic acid, active amino acids, and peptides providing an anti-aging clinical effect. The purpose of this research is to study in vitro new signaling molecules with the anti-aging effects and influence of hyaluronic acid fillers on its expression.
methodsThe study was conducted using cell cultures of human facial skin: 1) mixed culture of human facial skin keratinocytes and fibroblasts, and 2) culture of human facial skin keratinocytes enriched with Merkel cells. Immunocytochemistry, confocal microscopy and Western blot were used to identify markers of aging.
resultsHA-Y and HA-S activated the expression of Klotho in the case of aging mixed culture of human skin keratinocytes and Merkel cells. The increase in expression of MTH-1 with aging of cultures provides evidence of activating defense mechanisms against reactive oxygen species that are accumulating with aging, under the action of HA-S and HA-Y. There was a statistically valid increase in the area of expression of melatonin receptor 1A and 1B markers when adding both HA-S and HA-Y to cultured cells.
conclusionThis investigation showed that the studied fillers have biological effects, testifying the stimulation of reparative processes in the skin under their control.
