Seeing how Duchess Amelia seemed to have aged so much in the span of three months because they were missing, Stella thought of making something for her mother.
Dr. Arnold said that Duchess Amelia's condition was due to stress and anxiety. It resulted in insomnia and a lack of appetite that she barely ate. Dr. Arnold had prescribed medicine and vitamins to the duchess but it did not help much due to her misery and longing for her children.
As such, since they returned, Stella and Hendrick had been putting more food on the duchess' plate. They dined with her for breakfast, lunch, and dinner to make sure she eats.
'Hmm, a face cream against wrinkles and aging. Mother had been eating properly since we came back.'
After about four years of using her lab and experimenting with various products, she already successfully made a lot of products.
