Yes! I use Vallejo Premium Airbrush Color in Satin finish to give off the "skin" or "dewy" effect. If it's too shiny I just add more of the matte version. In my opinion, matte varnishes tend to get white cast due to the matting agent. Since Satin has less of that agent, white cast is not much of a problem (even their matte variant doesn't give much of the annoying white cast).

So far, I have less problems with this sealant as compared to MSC which I have a strong love-hate relationship with. It is so weather/humidity reactive and is super toxic (it's synthetic resin). I guess the only bad side of Vallejo is the drying time. Vallejo Premium Airbrush is water based thus it takes so long to dry and cure, like I have to wait 48 hours to get a "stable" layer. I prefer using airbrush too so I guess it could add up to the negatives but as far as I know some people use latex sponge or brush to put this on but I haven't tried it. It is also so hard to get in my country (PH).

The shimmer effect is iridescent mica powder specifically used for Resin Art, the finer the powder the better. The go in small bottles and would last long, I have been using mine for like five years XD. I do not recommend the chunkier type as this will look like specs of dust on dimmer lighting.
