What should you know about eyebrow frown lines?

These lines are also called glabellar lines or ‘11 lines’. They may show first when you frown, concentrate, or squint, then remain visible while your face is relaxed as the skin becomes less flexible. Dryness can make their surface look more marked, while bright light may encourage squinting. Their appearance does not reveal your mood or personality, and they are not usually a sign of a serious medical problem.

Use broad-spectrum sunscreen, sunglasses, and a gentle moisturiser to limit further sun-related change and surface dryness. Avoid deliberately holding a frown and choose skincare that does not sting or irritate. A qualified clinician can assess whether relaxing the muscles with a botulinum toxin injection or adding support with dermal fillers is appropriate. These treatments have different purposes, and fillers near the eye and brow area require particularly careful assessment.

Arrange a medical review if a new brow-area mark comes with a persistent rash, swelling, pain, bleeding, crusting, or a changing pigmented spot. Seek prompt care for sudden facial weakness, trouble speaking, severe headache, or vision changes. For cosmetic concerns, a dermatology or aesthetic consultation can clarify whether the line is mainly dynamic, etched into relaxed skin, or related to another skin issue.

Ask what is driving the line when your face is still, which treatment goal is realistic, and whether your medicines, pregnancy plans, allergies, or previous injections affect your options. You can also ask who will perform the procedure, what temporary effects to expect, and how follow-up will be handled.
