| Abstract |
Although topical creams and other anti-aging products purport to reduce the appearance of aging and skin wrinkling, there has been no critical analysis in the scientific literature of their effectiveness. This systematic review critically evaluates the evidence for the effectiveness or efficacy of botanical treatments in reducing skin aging and wrinkling. MEDLINE, Embase, CINAHL®, CENTRAL and AMED databases were searched from their inception until October 2009. Reference lists of retrieved articles were hand-searched. Manufacturers and professional associations were contacted in order to identify further non-published studies. No language restrictions were applied. Only randomized clinical trials or controlled clinical trials assessing the effectiveness of botanical extracts in reducing wrinkling and aging of the skin were included. Data were extracted by two independent reviewers and methodological quality was assessed using the Jadad score and key aspects of the Cochrane risk of bias tool. Of 36 potentially relevant studies, 11 trials of botanical extracts for reducing skin wrinkling and the appearance of aging met all the inclusion criteria. No trials were identified following contact with anti-aging and cosmetic organizations, companies and professional bodies. A significant reduction in skin wrinkling was noted for date kernel extract, cork extract, soy extract, Rosaceae and peony extract. No significant reduction was noted for green tea, Vitaphenol® (a combination of green and white teas, mangosteen and pomegranate extract) or maca root. All trials were of poor methodological quality. Adverse effects were frequently not reported. In summary, there is some weak evidence to suggest that several botanical extracts may be effective in reducing the appearance of skin aging but no evidence that this effect is enduring. Independent replications with larger, more diverse samples, longer treatment durations and more rigorous study designs are required to validate these preliminary findings. |

Attention Score in Context
This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 February 2022.
All research outputs
#2,863,756
of 25,373,627 outputs
Outputs from Drugs & Aging
#178
of 1,293 outputs
Outputs of similar age
#19,432
of 187,863 outputs
Outputs of similar age from Drugs & Aging
#40
of 372 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,293 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.3. This one has done well, scoring higher than 85% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 187,863 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 372 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 88% of its contemporaries.
