I didn't find the default version of that skin and I have no idea how to do that, which is too bad.
What is also impressive is all the dots on the arms/hands/forearms but I can't post a pic as I stripped the models afterward to check the bodies but the arms and hands look amazing. It works for teen through elder sims and is able to go over male or female skin. HOWEVER I did find one skin - which I don't use as it's not default and doesn't look right next to any other skin and I also think the elder skin colors are way too much pronounced, but it's highly detailed, specially for the elders, you probably know it already but whatever: RockTheSims - A MATTER OF SKIN don't be fooled by the 'casual' pics, here's a real ingame pic from my game: (the sim only have lipstick) Sims 4 Skin Details to Make Your Sims GORGEOUS (Skin Mods)>50 Sims 4 Skin. So I'm now happy with my elders as they finally look like elders - without me spending all my time in CAS to layer all that. I was never happy with the elders appearance until I used Consort's mode 'Age' which is amazing! Now I always have a shock when a neighbor sim passes by and it's an elder since the mod will do all it can to make him/her look more and more devastated by the age, day after day, walk and posture included. Indeed there's nothing much for the elders, a couple of facemasks (barely wrinkled in fact) and that's it, you'll only find a couple of items and clothes.
