모든 뷰티 제품이 그렇듯, 제품 효과는 제품을 계속해서 사용하는 동안에만 발휘됩니다.
For hair serums, like GRO 헤어 세럼 or GRO+ Advanced 헤어 Serum, since the growth cycle is longer, you'll see your hair return to its natural state in a few months after discontinuing use.
If you stop using the lash or brow serum, things will return to their natural state in about a month, since that's the length of a growth cycle. The serum works on your existing lashes and brows, and since all hair grows in cycles, once the hairs shed naturally you'll see your results fade.
