Long-term results after glabellar line excision:
1. After the excision of glabellar lines (the "11" lines between the eyebrows), new lines will not form at the specific site of the incision.
2. With proper care and by avoiding habitual frowning or sleeping on one's side or stomach, new glabellar lines are unlikely to develop in the area between the eyebrows.
3. If frowning is severe, periodic Botox injections following the excision can inhibit the frowning motion, effectively preventing the formation of new lines in the surrounding area.
