I think the foundation of skincare is hygiene.

Skin experts and the medical community cite proper hand hygiene as the beginning and end of preventing skin problems. The reasons and importance are as follows.

1. Removal of Bacteria and Contaminants (Prevention of Skin Troubles) In daily life, human hands come into contact with various objects such as doorknobs, smartphones, and public transportation, exposing them to various bacteria and viruses. If you touch your face with these contaminated hands, bacteria can penetrate the pores and cause acne, skin troubles, or dermatitis. Hand washing is essential, especially if you have a habit of resting your chin on your hand or touching your face.
2. The Start of Proper Skincare: If you do not wash your hands before applying cleanser or basic skincare products, contaminants from your hands will transfer directly to your face. Washing your face with clean hands allows the cleanser to lather sufficiently and effectively removes unnecessary impurities from your face.
3. Proper Handwashing Habits (The 30-Second Miracle): Simply wetting your hands with water is not enough. You must use soap and wash thoroughly under running water for at least 30 seconds, making sure to wash between your fingers and under your fingernails, to effectively remove germs. In conclusion, no matter how expensive the cosmetics you use, they are useless if your hands are not clean. A handwashing habit is the most economical and effective way to prevent various infectious diseases, as well as maintain skin health.
