Are these Botox lines normal? I have creases above my eyebrow, and they were never there before (Photo)

Those lines that have appeared above your eyebrow are from a partially under-treated frontalis muscle.  This is not uncommon when the injections are kept high above the brow, so not to cause them to droop.  The solution is simple: sprinkling a little extra Botox in the area of those wrinkles will help to soften them.  This is optimally done at least 2 weeks after the initial treatment, so the full effect of the initial treatment is apparent.  

This is a common side effect of attempting to limit over treatment of the forehead, or can also occur when trying to raise the tail of the eyebrows with a little botox. Placing 2-3 units right under the skin in that area can limit the creasing and should not run the risk of dropping the brow. Best of luck in achieving your desired result!
