1. It depends on individual skin type and needs: If your skin type is good, your skin tone is uniform, and you can already meet your basic daily grooming and protective needs after using isolation cream, then you can no longer use BB cream.
2. The functional difference between barrier milk and BB cream: Barrier milk mainly serves to isolate makeup, external pollution, and ultraviolet rays, and some also have the function of adjusting skin tone but are relatively weak. BB cream has multiple functions such as stronger concealer, whitening, moisturizing and sunscreen, which can more comprehensively modify the skin color and texture.
3. Precautions for overlapping use: If you want to get a better concealer effect and skin color modification, you can continue to use BB cream after applying isolation cream. However, it should be noted that the combination of the two may increase the thickness of the makeup and affect the breathability of the skin. Especially for people with oily or combination skin, caution should be exercised to avoid pore blockage or excessive makeup. At the same time, when using in combination, the dosage should also be controlled to avoid excessive makeup.
