To be honest, I did not make up these topics out of thin air. Last year, I stayed in the beauty center of the dermatology department of a tertiary hospital for half a year. I screened the project proposals of three students with my tutor, and also conducted user research for two functional skin care products brands. These topics are either controversial points that are hotly debated in the academic world, or questions that the industry wants to find answers to. They are much easier to implement than those fake topics that you can search for.

Take the issue of the long-term safety of low-concentration acid use. One group in the ingredients party circles is the "all-purpose acid-cleansing group", saying that using 0.5% salicylic acid every day can brighten and control oil, and can be used even on sensitive skin. The other group is the evidence-based group in dermatology, saying that long-term and uninterrupted use of acid will destroy the lipid structure of the stratum corneum, and will instead induce acquired sensitive skin. Each side has its own small sample experimental data, and no one can convince the other. A master's student chose this topic the year before last. He found 60 18-25-year-old volunteers with healthy skin and divided them into three groups. One group used 0.5% salicylic acid essence every day, one group used it every other day, and the other group used a placebo base. The group was followed up for a full six months. Finally, it was measured that the group that had been used continuously for more than 3 months had an average transepidermal water loss rate of 27% and a 12% thinner stratum corneum thickness. The conclusion is that low-concentration acids are not recommended for continuous use on healthy skin every day. After this research came out, it was directly purchased by three skin care brands to use as the basis for product claims. It also won the provincial outstanding master's thesis that year.

Oh, by the way, one more thing to remind you. If the topic you choose involves human experimentation, you must get ethical approval in advance. Don’t wait until you are stuck halfway through. I have seen several students whose papers were rejected because they did not follow the ethical process. The gain outweighs the loss.

If you just want to write a course paper for an undergraduate degree, there is really no need to do basic research like cell experiments and raising mice. It is too time-consuming and prone to problems. Just choose a research type. For example, send hundreds of questionnaires to schools and conduct a survey on teenagers' skin care cognition. You can collect the data in a week, and the things you write out will also have practical significance. I met a marketing student before, who chose the topic of Xiaohongshu’s beauty content’s impact on teenagers’ skin care decisions. She crawled through 100,000 whitening-related notes on Xiaohongshu, and went to two local middle schools to do more than 20 in-depth interviews. Finally, she found that 62% of junior high school students who bought whitening products read the notes of Internet celebrities, and nearly 40% of them bought unregistered Sanwu products. The report was eventually used by the local health commission as a reference for youth skin care science. It is much more practical than many basic research papers.

When choosing a topic, many people always think that the newer the better. A few years ago, when fullerene was popular, a lot of people gathered to study the skin care efficacy of fullerene. In the end, they found that the purity of fullerene raw materials on the market was as poor as 10 times. The experiments were impossible to reproduce, and most of the effort was wasted. On the contrary, there are "old questions" that everyone has been arguing about for several years, such as whether to build tolerance to nicotinamide and whether functional products can be used after medical and art studies. These questions may not seem new, but as long as you design the experiment more rigorously and the sample size is larger, the conclusions you draw will have more reference value.

By the way, if you are interested in traditional Chinese medicine, you can definitely try research on ancient Chinese medicine prescriptions for beauty. Nowadays, there is a lot of controversy in the academic circles in this direction. One group thinks that ancient prescriptions are all metaphysics and have no modern scientific basis. The other group thinks that many of the medicines in ancient prescriptions The ingredients are indeed active. For example, the Bletilla striata and White Poria cocos in Yurong Powder used by the Empress Dowager Cixi have now been proven to inhibit tyrosinase. As long as you concentrate on extracting the ingredients and verifying the activity, no matter what conclusion you draw, you can fill in a lot of research gaps.

In fact, there is not much emphasis on choosing a thesis topic. Either you are really interested in it, or it can solve a small practical problem. Don't choose something that you have no idea about just to make up for the hot spots. By then, you won't be able to continue the experiment and it will be too late to cry. If you are not sure whether the topic you chose can be solved, it is better to search relevant literature in the past three years to see if anyone has done it and whether there are mature research methods available. Then ask practitioners in the industry whether anyone really cares about this issue. It is better than working behind closed doors.
