I say, and with God's success: If this is for the purpose of beautifying for the husband, and it does not cause harm, then it is permissible and not forbidden. It is known that applying such eyelashes prevents the validity of ablution, as water does not reach her natural eyelashes. There is no reason among the jurists called changing God's creation, and beautification is not considered an objection to creation. Rather, God Almighty has created certain excesses in our bodies, such as hair, and has asked us to remove and purify them. This is not changing God's creation; rather, we say that God is beautiful and loves beauty, and a woman is required to beautify herself for her husband with all her ability. And God knows best.
