Application Time: It is recommended to apply sunscreen 15-30 minutes before going out, so that the sunscreen can form a uniform layer on the skin surface. Just imagine a loose and slack sunscreen formation, how can it withstand the fierce attack of ultraviolet rays?
Amount to Apply: It is recommended to apply 2mg/cm2 of sunscreen. Approximately the size of a coin (about 1g) is needed for one face. (Be careful, a 30g bottle of sunscreen can last for two months and still not be finished). If the amount applied is insufficient, the sunscreen effect will be greatly reduced. For example, with SPF50 sunscreen, if only 1 mg/cm2 is applied, the actual SPF is only 7.1.
Application Technique: Gently apply along the direction of the skin texture and let the sunscreen film dry naturally. Pay attention, when applying sunscreen, never apply too much force, too vigorously, or rub for too long, as this will damage the film-forming properties of the sunscreen and easily cause it to “pill”, reducing its sun protection effectiveness.
Sequence of Use: Of course, if you want to save trouble, in environments where high sun protection factor is not required, sunscreen can be replaced with sunscreen-containing primer. In addition, foundation should be applied after sunscreen or primer has fully formed a film, otherwise makeup may cake or become patchy. Remember to clean and remove makeup after use!
