Hello Interloper!

When skin boosters such as Profhilo, Sculptra, NCTF, PhilArt, Nucleofill, SeventyHyal etc come on the market, they usually fail to make a big deal of which types of collagen they increase in the skin. When we know that increasing certain types of collagen, e.g. type XVI, is highly linked to disease (Akagi 1999), one would be forgiven for becoming extremely frustrated at brands not being fully disclosive and/or not making a big deal of which collagens they promote.
The promotion is based on increasing ‘skin tightness’ as a generalisation.
After all, who doesn’t wish to keep their face youthful while slowing the ageing process?
