How waterproofing works
The silicone forms a film that repels water, helping to maintain the effectiveness of sunscreen and other products.
About clogged pores
Because the product forms a film to coat the skin, some people worry that it may clog pores, but because silicone molecules are large, it is said that there is no need to worry about clogged pores.
Silicone is found in a variety of products.
It is used not only in sunscreen, but also in skin care products such as lotions and milks, shampoos, conditioners, and toothpaste.
Because it is chemically stable, it has excellent heat resistance and is said to be safe to use without worrying about deterioration, but there are some precautions to take when using it.
1. Dry skin
If this film remains on the skin for a long time, the sebum dirt may oxidize, causing skin problems, or the normal secretion of sebum may be hindered, resulting in dry skin.
Even on days when you only use sunscreen, be sure to remove it properly with cleansing products.
② Difficult to fall off
Since silicone does not mix well with either water or oil, depending on the amount of silicone used, it may be difficult to remove without strong cleansing.
*If volatile silicone is used or only a small amount of silicone is used, there are also types that can be removed with soap.
There will be many situations in which waterproofing is essential, such as when going out or on leisure trips. Be sure to check the instructions on the package and use the product properly to avoid skin problems.
