@haenaaa58: Replying to @Elxiang Culaban Beginners should start by building skin tolerance first. First 2 weeks: 2-3 times a week if no irritation, you can increase frequency on 3rd and 4th week— apply the serum every other night If still working good on skin, 5th week onwards— may apply every night. PS: Do not apply on active pimple. BUILD. TOLERANCE. FIRST. ❗️Disclaimer: I am not a dermatologist nor a skin expert. This is my own opinion based on my knowledge and personal experience only. #rejuvenatingserum #smoochkinszeedleshots #pdrnserum #spiculeserum #skincare
