>>2380234I try not to use the "lipstick print" face marking for actual lips. It can be made to work for some mouth shapes (as shown here) but not most of them. I find it's more useful to redraw the shape of lips with several other markings and then distort that according to the mouth shape you want to use.
For glossy lipstick I used marking 16 on the lower lip and 15 on the upper lip. 1, 15, 16, 30, or 31 seem to be what I end up using to make more stuff than anything else.
I wrote all that for the benefit of anyone else. all you really need to consider trying I think is using smaller, brighter spots of illumination. And more trial and error because that's kinda what you have to keep doing when using something like this.
