Sunscreen skin care: Provide long-lasting sun protection, prevent direct damage to the skin by ultraviolet rays, and prevent sun spots, sunburn and photoaging. Brighten skin tone: The brightening ingredients in some products can improve dull skin tone and make the skin look brighter and more radiant. Moisturizing and nourishing: Some isolation sunscreens also add moisturizing ingredients, which can not only protect the skin from sun damage, but also provide moisture and nutrition to the skin to keep the skin moisturized. Cleansing: Before using isolation sunscreen, you need to thoroughly clean your facial skin to remove oil and dirt. Apply appropriate amount: Take an appropriate amount of isolation sunscreen on the palm or fingertips, and then apply it evenly on the face, neck and other parts that need sun protection. Be careful not to apply too thick or too little to avoid affecting the sun protection effect or causing waste.
