Why do all my Sims look the same!

I tend to favor the same type of looks in CAS, so they tend to look the same. I do change a few things, but always have the bad habit of kind of bringing it back to the look I was trying to avoid, which is the sameness.
What I do to split up looks and vary my Sims is downloading other Sims from the Gallery. I would make one male, or female, and download a Sim I liked from the Gallery, and mix their genes. I've gotten unique looks I wouldn't have otherwise gotten.
Only do the Gallery thing if CAS doesn't really work for you.

Probably a silly question, but you are aware that you can go one extra detailed level into face CAS? It opens for a lot more uniqueness, like smaller/bigger/happy/sad etc. I don't think you can adjust the head shape in there, but most details that will make your sim stand out.

In my opinion, @Umbreon12 had the best answer in this thread. I am aware of the detail CAS and the randomize thingy. But the problem was I always went for Sims who I favored for, which caused the sameness in my game.

Glad I could help.
From the Gallery I download Sims I like, and mix them with Sims I created, or with each other. I have gotten quite a bit of Sims that are similar to what I like/create, as well as unique looks that I wouldn't have come up with in the CAS.

Yeah, I've had issues with that too lately... You see my avatar right? Its kinda hard to get away from that face style for me because I really like said face style... And while Male faces CAN get close to the same narrowness seen in avatar picture, its not quite as narrow due to the base body frame overall being beefier.

And its a combination of Alien and vampire genetics too, which is not everyone's favorite thing. But you might get somewhere the furthest if you push yourself to try a new or different set of genes. Also, the skin color selection does have sliders on each if you so desire. Trouble is, they usually are not saved past the creation stage that I've seen.

Hope you can succeed in your goal.

You're going to have to go with making ugly Sims with bad style if you don't go the cc route. I'd just accept that and use all the ugly hair styles and clothing I assume you keep reusing the same couple items over and over which is making your Sims look similar because things like facial hair and hair really do change each Sim drastically. I won't even use the same hairstyle on 2 Sims in the same color mostly I don't even do that unless it's one I really like.

One thing I’ve done that works really well to generate novel sims is to create an interesting man, and then make him female, or vice versa.
