How long does botox take to work for frown lines?

Frown lines, also called glabellar lines, form as muscles between the eyebrows repeatedly draw the brows together. Botulinum toxin interrupts the nerve-to-muscle signal temporarily. You may notice less force when frowning before the skin looks fully softened. A crease that remains at rest can be more established and may not respond as fully to muscle relaxation alone.

Keep facial cleansing gentle and follow the clinic’s instructions about activity and touching the area. Allow the planned review to guide any decision about refinement. Before future injections, discuss prior reactions, medicines that affect bleeding, pregnancy or breastfeeding, and any neuromuscular condition. Avoid comparing the result hour by hour; gradual change is expected.

Report troublesome brow or eyelid drooping, marked swelling, worsening redness, significant pain, or visual symptoms to the treating clinic. Seek emergency care for breathing or swallowing difficulty, speech changes, or weakness beyond the treated area.

What degree of frown movement should I expect to retain? When should an uneven result be reviewed? Could my resting crease need a separate treatment?
