From the perspective of skin care, the stratum corneum is not closed after applying the mask. The fragrances and preservatives in the makeup can easily enter our skin and cause clogging of pores. From the perspective of makeup, applying a mask before makeup can make the makeup look better. Then how should we solve this question? The correct way is to apply makeup 30 minutes after the mask is applied. That is because the stratum corneum has been closed after we have applied the facial mask 30mins.
