If you were to try and tell me the skin care products you're thinking of. and is used on the dressing table In addition to products such as toners, essences, serums, creams, and facial masks, I believe that sunscreen is another answer that people will definitely not forget.

Miss Derma also recommends that everyone should use sunscreen products. The starting sunscreen value that many experts agree on is recommended to be at least SPF15, and for safer protection, choose to use sunscreen products with a value of SPF30 or higher.
Believe it or not, there is a research study asking volunteers about the amount of sunscreen products. Or even survey from ourselves and the people around us that we know. It was found that using less than half the recommended amount per time (25-50%) and of course because when you use an insufficient amount The effective results of sunscreen protecting the skin may not be as much as stated on the packaging label. The proportion for calculating the amount of sunscreen product used is 2 milligrams per square centimeter of surface area (2 mg/cm2), but you don't have to rush to find a tape measure, tape, or ruler and put it on your face to calculate the surface area which is difficult. Miss Derma would like to share tips instead. For the face and neck, use the "2 finger rule". Squeeze 2 inches of sunscreen from the beginning to the tip of your finger (on the index and middle fingers). For the body, the amount is about 1 ounce or so. 1 shot glass.

Therefore, continued use of sunscreen products is also recommended.
Sunscreen should be used at least 15 minutes before going out into the sun. So that the sunscreen in the cosmetic formula can spread and set like a dry film evenly on the skin. Including not getting wet on clothes. And it is recommended to reapply every 2 hours or in cases where the skin is exposed to water. or sweat This is because in cosmetic formulas there are sunscreen types, either Chemical, Physical or Hybrid, mixed in large or small proportions according to each formula. With the working principle of Chemical that absorbs radiation and converts it into heat or Physical that uses the principle of reflection but the amount decreases from the skin when washed away with sweat, water or contact with the body. Therefore, their effectiveness can be degraded over time.
Even though we didn't leave the house or inside the building Wearing sunscreen is still necessary because rays can pass through window glass. Wearing clothing to cover your face, a hat to cover your face, and sunglasses are also ways to relieve damaged skin from being damaged by the sun.
