Smoothing Forehead Lines: What to Know

Horizontal forehead lines often become more visible when you raise your eyebrows or concentrate. Repeated contraction of the forehead muscle can fold the overlying skin; with time, lines may remain noticeable when the face is relaxed. Sun exposure, dry skin, smoking, and normal changes in collagen can make texture easier to see. Wrinkles are a common surface change, but their depth and pattern vary between people.

A consultation distinguishes movement-related lines from a rash, a new swelling, or another skin concern. You can read more about [Wrinkles](/symptoms/wrinkles/) as a related symptom.

Use broad-spectrum sunscreen, sunglasses, and a moisturiser suited to your skin. Avoid tanning and repeated squinting when possible. A clinician may discuss a neuromodulator such as botulinum toxin injection when muscle movement is the main contributor; it temporarily reduces targeted muscle activity and requires an assessment of facial balance. Other options may be considered when lines are visible at rest, including topical retinoid treatment or resurfacing, depending on your skin and medical history.

Ask about the expected onset, duration of effect, aftercare, and alternatives before treatment. Do not inject the area outside a regulated clinical setting.

Arrange a medical review if a forehead change is new, one-sided, painful, itchy, bleeding, crusted, rapidly changing, or associated with weakness, numbness, severe headache, or vision changes. These features do not fit ordinary expression lines and may need prompt assessment. Seek urgent help for sudden facial weakness, confusion, or a severe sudden headache.

Which part of my lines is caused by muscle movement? Would botulinum toxin injection, a topical treatment, or resurfacing suit my skin? What side effects, follow-up, and timing should I expect? How should I adjust treatment if I am pregnant, breastfeeding, taking medicines, or prone to pigmentation?
