The latest study of West China Hospital: Applying mask, time is the key.
In this era of "emphasis on refinement", facial masks have become a must-have in many people's hearts. Whether it's a self-treat after a busy day or a small ritual to relax on the weekend, a facial mask can always bring instant relief and satisfaction.
However, reviews of facial masks on the Internet have always been polarized,
- Some people think that the mask is essential, and the mask can help the skin moisturize and delay aging;
- Others believe that the mask is an IQ tax, and believe that the mask is just a marketing gimmick of the business;
- Some people also complain that wearing masks instead leads to frequent skin problems and even "rotten face"......
So, is there any use in applying a mask? How much do you spend on facial masks each year?
In order to scientifically answer these questions, the research team of the Cosmetics Safety and Efficacy Evaluation Center at West China Hospital of Sichuan University conducted a randomized controlled trial, which not only revealed the best time to use the mask, but also provided scientific guidance for consumers to avoid skin problems caused by the wrong use of the mask.
Applying a mask is useful, but time is key, do not > 25 minutes
The results of the experiment showed that short-term use of the mask (less than 25 minutes) can significantly increase the moisture content of the skin, but this increase will gradually decrease over time. This shows that short-term use of the mask can effectively increase the moisture level of the skin, making the skin look more moisturized and smooth.
Studies have found that short-term use of the mask can reduce the occurrence of skin erythema. Especially when using hyaluronic acid mask and bifida yeast fermentation product mask, the reduction effect of erythema is more obvious.
Using a mask for a long time can backfire!
1. Over-hydration: Prolonged use of the mask (more than 25 minutes) may lead to over-hydration of the skin, which in turn damages the skin barrier function.
2. Increased sebum secretion: Experimental results show that all types of facial masks will increase sebum secretion, especially under 40 minutes of wearing time, sebum secretion increases significantly. This can lead to clogged pores, leading to breakouts and other skin problems.
3. Adverse reactions: Long-term use of the mask will lead to more adverse reactions, such as erythema and dryness.
Brief summary
In summary, using the mask for a short period of time (less than 25 minutes) is beneficial to the skin by increasing skin moisture, reducing erythema and activating AQP3, thus maintaining the water and oil balance of the skin. However, prolonged use of the mask (more than 25 minutes) can lead to dry skin and erythema, and even other skin problems. Therefore, the scientific and reasonable use of facial masks, following the correct wearing time, is the key to maintaining skin health.
