This semester's public elective course, I am honored to choose beauty pharmacology.

I first heard this name when I was a freshman. At that time, I had not taken a public class. A senior told me that she was taking a beauty exam. At that time, I thought it must be a very difficult course, and it should be about the pharmacology of skin care products.

Then listen to the teacher elder sister's explanation. This is a very useful lesson, where you can learn how to protect skin and which skin care products are better to use.

From this, I began to yearn for the course of beauty.

From the basic knowledge taught by the teacher in the first class to the brand introduction of skin care products in the last class, I believe that girls who cherish themselves have benefited a lot.

Especially for some misunderstandings of daily nursing, I learned a lot in this course. Now list some of your gains.

1, the misunderstanding of facial cleanser. Because my skin is yellow and oily, I hope facial cleanser can not only clean, but also control oil, clean and whiten, which is very convenient.

So I used XX's whitening foam facial cleanser (of course, I didn't realize its whitening function in the end). In this class, I learned that facial cleanser only needs to be cleaned, such as whitening and other functions. Because it stays on the internet for a short time, it is difficult to have an effect, so now I am not pursuing its whitening function, but paying attention to its cleaning function.

2, the misunderstanding of sunscreen. Some time ago, I bought a bottle of XX multiple protective isolation spray, which was specially applied to my neck, shoulders and arms. But because this bottle is not cheap for me, it is also a little economical in dosage.

Last time the teacher told me about sun protection, I realized my mistake. Insufficient sun protection and weak ultraviolet protection will also tan. If I use it sparingly, it won't be worth the loss, and I didn't get a tan after spending money. So I changed my previous idea and will make it up every two hours (outdoors).

3. Understanding of skin care products containing alcohol and preservatives. In the past, like everyone else, I thought that skin care products containing alcohol and preservatives must be bad and will hurt the skin, thinking that they are all natural.

However, in the beauty class, my idea was subverted. Those pure natural products are not necessarily better than those with preservatives, which makes me no longer resist preservatives. At the same time, it also made me less gullible. I bought some pure natural products and got cheated!

For example, I still have many misunderstandings. Many of my ideas have changed in this class. And have a further understanding of skin care knowledge.

As the saying goes, there are no ugly women, only lazy women. Looking at the skin of the old lady Tanaka, I can't help but sigh that the maintenance work must be done well, otherwise it will be difficult to remedy when I am old.

Time flies, time flies, this course is over. The course of beauty pharmacology is like a lamp, which leads me into the door and lets me spy on the secrets of skin care and makeup, and finally benefits me a lot.
