1. You can only apply isolation cream and not apply anything else. Isolation cream is mainly used to protect the skin and prevent direct damage from external environments such as UV rays, dust, makeup, etc. It also has a certain moisturizing effect.
2. However, if you want a more complete look or need a better sunscreen effect, it is recommended to apply sunscreen, liquid foundation or BB cream after the isolation cream to further enhance the sense of makeup and protection.
3. Whether or not to continue applying other products, keeping the skin clean and moisturized is the foundation, ensuring that the skin is covered by cosmetics in good condition.
