What should you know about brow frown lines?

The muscles used for frowning, concentrating, or squinting pull the skin between the brows into folds. Over time, lines may remain visible when the face is relaxed, while early lines may appear only during expression. They are a form of [Wrinkles](/symptoms/wrinkles/) and are not, by themselves, a sign of illness. Sun protection, moisturising, and avoiding tobacco exposure can support overall skin quality.

Use sunscreen daily and choose a gentle cleanser and moisturiser. A clinician may discuss botulinum toxin injections when muscle activity is the main driver. This temporarily reduces targeted muscle movement and requires assessment of facial anatomy, medicines, allergies, and treatment goals. [Botox](/treatments/injectables/botulinum-toxin-injection/) is a brand-associated term for this type of treatment.

If lines remain etched when the face is still, a clinician may discuss resurfacing, skincare, or carefully selected [Dermal Fillers](/treatments/injectables/dermal-fillers/). Fillers are not suitable for every glabellar line, and injection near the eye and forehead region needs an experienced medical practitioner.

Seek assessment if a line is accompanied by a new drooping eyelid, facial weakness, severe headache, vision change, or sudden neurological symptoms. For cosmetic concerns, arrange a consultation when the crease changes quickly, follows an injury, or bothers you despite basic skin care. Ask about expected onset, duration, and aftercare before any procedure.

Ask whether movement or skin texture is the main contributor, which option fits your anatomy, what temporary effects can occur, and when a review would be needed.
