Upward trend in number of injectable treatments in the
Netherlands 2016– 2019
To the editor
Little is known about the incidence of injectable cosmetic treatments
and adverse events associated with these treatments. The American
Society of Aesthetic Plastic Surgery (ASAPS) and the International
Society of Aesthetic Plastic Surgery (ISAPS) provide numbers on in-
jectable treatments, but the data are from their members only and
the response rates are low (5%).1,2 Therefore, these results cannot
be extrapolated to a general population.
In 2016, we published the results on the number of injectable
treatments in the Netherlands based on a postal survey sent to all
doctors in the country who performed injectable treatments.3 To
identif y these doctors, we used Google Internet Search, Dutch
Archive Data Care Register, and membership lists of all professional
specialty associations.
Using this same method, we repeated the survey for the number
of treatments performed in 2019. The search yielded a total of 305
eligible doctors. A total of 99 doctors responded (response rate of
32%), of whom 63 (64%) provided exact numbers and 26 (26%) gave
estimates. We used the same method to estimate the total num-
ber of treatments. Total numbers of botulinum toxin (BTX) and sof t
tissue filler treatments are presented in Table 1. The male/female
ratio was 1:8, and the average age was 43.2 years. Since the scien-
tific societies of all professional specialty associations recommend
treating only persons between 18 and 70 years of age, a total of
5.907.1904 women and 5.934.2774 men were eligible for treatment
in the Netherlands. Considering the male/female ratio and the fact
that treatments with BTX are usually given twice yearly and soft
tissue fillers once yearly (Velthuis et al., unpublished results), this
would mean that in 2019 one out of every 53 women (5.907.190/
(0.888 × 124.494) were treated with BTX , and one out of every 41
(5.907.190/0.888 × 162.702) with soft tissue fillers.
The numbers in 2016 and 2019 are remarkably consistent, sug-
gesting that they could represent the actual numbers in the gen-
eral Dutch population. In this 3- year period, the number of filler
treatments increased by 12%, whereas BTX treatments diminished
slightly. This is in line with the international data from ASAPS and
ISAPS.
Our estimate that 1 out of every 41 women has undergone filler
treatment was surprising, as this makes filler treatments one of the
most popular aesthetic medical intervention in terms of annual fre-
quency. We expect these numbers to be similar to those in other
Western countries or even slightly higher, thanks to the influence
of Dutch Calvinism.5 The popularity of filler treatments in Asia and
Latin America might be even higher.
Our department holds consultation hours for filler complications,
is based in the center of the Netherlands, and can be reached within
a two- hour car drive from ever y place in the country. Although we
acknowledge that not every side effec t will be referred to our clinic,
almost all serious ones are. The most serious adverse events are
vascular adverse events (VAE), which we see almost twice every
month.6 Gi ven the calculate d total number of tre at ment s, VAE occur
in 0.014%. During the last 5 years, the mean number of referred pa-
tients with other adverse events from hyaluronic acid fillers was 50
and for BTX it was 5. Hence, the calculated risk for serious HA filler
complication is 0.03% and for botulinum toxin 0.002%.
Cosmetic injectable treatment s have become an important par t
of aesthetic medicine and entail very low risks of serious adverse
events.

John Calvin and Reformed Protestantism interlinked questions of life and death with questions of faith. Not only faith and the church, but life in general call for constant renewal through the word of God. These processes of renewal incorporate society and the economy. In contrast to the popular assertion that Calvin and Calvinism are responsible for capitalism and its aberrations, Calvin in particular shows a deep sensibility for human beings trapped in economic deprivation. In his sermons Calvin exhorts the rich to consider the poor as ‘their’ poor and to thank God by practicing generosity. This appreciation of social questions within an ecumenical context is demonstrated in the Reformed church in a whole array of charitable services. It will be crucial for the current debate on economic ethics to assess economic processes in relation to how they serve life. For it is liberty, justice and fellowship – as gifts of God – that serve as an orientation and an obligation to be aware of human beings suffering from the negative consequences of globalisation.How to cite this article: Freudenberg, M., 2009, ‘Economic and social ethics in the work of John Calvin’, HTS Teologiese Studies/Theological Studies 65(1), Art. #286, 7 pages.

Article
Objective data on the number of cosmetic injectable treatments (Botulinum Toxin A and fillers) performed annually is lacking. These numbers would be helpfull in establishing the importance of this area in medicine from a medico-social perspective and to determine the incidence of side-effect. Numbers on the number of treatments or global volumes used provided by the American Society of Plastic Surgeons (ASPS) and the International Society of Aesthetic Plastic Surgery are erestricted to their members.1,2 This article is protected by copyright.
