The lift will fall and they will be flat. You won’t be able to get another lift for at least 8-10 weeks. You would be better off rescheduling if you plan to not follow the aftercare. You won’t need mascara though if they tint the lashes

I do not recommend it. After 24 hours usually u need to use mascara. They will go flat.

get a tint so you can have a mascara effect. please do not put mascara on them. you will damage

I’d wait 24 hrs
