Topical Formulation with Niacinamide Combined with 5 MHz Ultrasound for Improving Skin Ageing: A Double-blind, Randomised, Placebo-controlled Clinical Study.
Trial report in Current medicinal chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 ageing is a complex process influenced by various factors. Personal care products claim to address ageing signs, yet clinical efficacy tests lack standardised regulations. Niacinamide (NIA) is known for skin benefits, including managing hyperpigmentation and enhancing the barrier function. The 5 MHz unfocused ultrasound (5-US) is a technological intervention for cutaneous ageing, lacking sufficient literature. This study aimed to clinically assess a topical formulation with NIA, combined with facial application of unfocused 5-US.
methodsSixty-seven female subjects (30-60 years) with signs of aged skin participated in the study. They were enrolled and randomised into four groups: (A) placebo formulation, (B) cosmetic formulation, (C) placebo formulation plus 5-US, and (D) cosmetic formulation plus 5-US. Groups C and D performed the aesthetic procedure of 5-US on the entire face, in a total time of 20 minutes per session, once per week (eight total sessions). Clinical, instrumental, and subjective assessments were performed before (T0) and during the eighth week (T8) of the study.
resultsThe formulation with NIA improved stratum corneum aqueous content and reduced transepidermal water loss. Sebum reduction was observed in groups utilising the formulation. Consumer evaluations indicated improvements in appearance, firmness, elasticity, and reduced wrinkles, notably in Groups C and D. Sensory analysis indicated overall product acceptability.
conclusionThe formulation with NIA improved skin hydration and reduced sebum content in mature skin, while subjective evaluations indicated qualitative improvements in skin appearance. Although 5-US alone did not show instrumental improvements, protocol adjustments and longer study periods may yield better results. The comprehensive approach provides an innovative perspective into potential synergies, suggesting future directions for anti-ageing interventions in skin care.
