Your sims can have a skincare system and get acne if they don’t use their skin care appropriately.
They can have appearance changes when they have emotions like tears in their eyes when they’re sad or rosy cheeks when embarrassed. The first thing that this mod adds is a memories system where your sims are able to remember and talk about important moments in their lives.
This mod has so much going on inside of it and really adds realism to so much of your game. Slice of Life is one of the first sims 4 realistic mods I ever download and I’ve never gone back.
