With her long talk with Dr. Arnold finally over, Stella went to her personal laboratory.
When she was twelve, Duke Henry had built one for her when she did her own experiments on cosmetics-making. She was sure he didn't really understand what she was trying to do but he supported her endeavors anyway.
Hendrick even thought that she was truly trying to be a doctor and it took some of her time to explain to him that making beauty products (which he also did not understand and had to be explained) was much more complicated than it looks which is why she needed a laboratory for it.
After a lot of trials, Stella began making her own cosmetics starting from what was easiest for her to do.
Stella was a natural beauty but she also had to maintain it. She noticed that adult ladies must be using some kind of makeup since some of the ladies she had seen had their lips tainted red or pink.
