Frown lines between the eyebrows? Are there any prevention methods or patches that help?

Maybe it's because I've been getting angry at my child so much lately...

I feel like I get wrinkles between my eyebrows... so easily...

I'm worried I might end up getting stuck like Kim Gura.... ㅠㅠ

I've seen those forehead patches coming out lately... Has anyone tried them? What are they like?

Also, please let me know if anyone knows any tips on prevention methods or exercises for between the eyebrows...

I shouldn't frown, but I keep finding myself doing it...
