1. Apply towel for about 1/2 minutes to open the skin pores. Then apply the blackhead extracting liquid on the nose for 5-10 minutes. 2. Choose the tip that suits your needs, touch the skin and move the instrument slowly from top to bottom, do not pull the skin hard, and stay for no more than 2 seconds (the staying time is too long, the skin is prone to red and purple). 3. After treatment, wash your face with cold water or apply a freezing mask to shrink the pores. Then apply pore shrinking lotion or serum. The skin is tender and beautiful!
