Looking for a job, I saw a request by a skincare company looking for a scientific advisor/writer. It was a part-time job, paying a fraction of what I used to get as a research professor, but it was a job and I accepted gratefully. I did a good job, taking into account that it was my first contact with the "real world". I had no practical expertise, but my background was useful. Searching the scientific literature, I found neglected ingredients that could benefit the skin via biochemical mechanisms that I was familiar with (and some that I had to learn about). With my expertise in biochemistry, botany, and plant physiology I started advising and writing promotional articles.
