Smile Frown Lines: What to Know

Frown lines, also called glabellar lines, sit between the eyebrows and may look like vertical marks or an angled furrow. They appear when muscles draw the brows together during frowning, concentration or squinting. Over time, repeated folding and reduced skin elasticity can leave the lines visible at rest. Bright light, unprotected sun exposure and dry skin can make them more noticeable. They are different from lines at the outer corners of the eyes, and their position helps guide treatment planning.

Use sunscreen and sunglasses outdoors to reduce squinting and ultraviolet exposure, and moisturise if the area feels dry. If you want a procedure, a qualified medical professional can assess facial movement, brow position and skin quality. Botulinum toxin injections temporarily reduce activity in selected muscles. Dermal fillers add volume in carefully chosen areas, but they are not suitable for every crease or face. Discuss expected change, timing, side effects, aftercare and the experience of the injector before deciding.

Arrange a skin check if a mark changes quickly, becomes scaly, bleeds, crusts, remains painful or does not resemble your usual expression lines. Before an injectable treatment, disclose allergies, medicines, previous procedures, pregnancy or breastfeeding, and any active skin infection. Seek urgent help after an injection for severe or worsening pain, unusual skin colour, vision changes, weakness or trouble speaking.

Ask whether muscle movement or skin texture is the main contributor, whether Botox or filler is appropriate, what risks apply around the brow and eye region, and what follow-up would be needed.
