Forehead Wrinkles: Causes, Prevention and Treatment Options

Horizontal forehead lines form as a result of the repeated movements of the forehead muscle that raises the eyebrows and the loss of skin elasticity with age. At first visible only when the eyebrows are raised, these lines may over time become noticeable even at rest. This article explains the causes of forehead wrinkles, ways to prevent them and the treatment options.

What Causes Forehead Wrinkles?

• Repeated movements of the forehead muscle that raises the eyebrows
• Loss of collagen and elastin and thinning of the skin with age
• Sun damage to the skin
• Smoking and genetic predisposition

In some people, excess skin on the eyelids or drooping eyebrows can lead to the eyebrows being raised constantly to ease vision, which deepens the forehead lines. In this case, a treatment aimed only at the lines is not enough.

Prevention and Skincare

Regular use of sunscreen and protection from the sun reduce the sun damage that accelerates skin ageing. Moisturisers can help the skin feel more comfortable and look smoother. Vitamin A derivatives such as retinol can support skin renewal; because they can make the skin more sensitive to the sun, they are usually used in the evening, and a doctor should be consulted if irritation occurs. Stopping smoking and regular sleep contribute to skin health. Skincare products can help slow the formation of lines, but they do not correct established lines on their own.

Treatment Options

• Botulinum toxin: Softens lines caused by movement by temporarily reducing the strength of contraction of the forehead muscle. The effect is temporary and the treatment is repeated if needed.
• Forehead filler: In deep lines that are visible even at rest or in volume loss of the forehead, a filler containing hyaluronic acid can be applied with a careful technique.
• Skin resurfacing treatments: Methods such as laser, microneedling and focused ultrasound (HIFU) can help improve skin quality and the appearance of fine lines.
• Forehead lift: If there are drooping eyebrows and marked skin laxity, it can be considered as a surgical option.

Which method is suitable is determined at the examination according to the depth of the lines, the skin structure and the position of the eyebrows. In some people, more than one method may be planned together.

Limits and Realistic Expectations

Forehead lines may not disappear completely; the aim is a softer appearance. In people with drooping eyebrows, excessive relaxation of the forehead muscle can cause the eyebrows to drop further, so botulinum toxin is planned carefully in these people. The amount used is determined individually to preserve natural facial expression.

Possible Risks

After botulinum toxin treatment, redness and bruising at the injection site, headache, asymmetry of the eyebrows, and drooping of the eyebrow or eyelid may occur. With forehead filler, in addition to swelling, bruising and irregularity, a rare but serious risk is the filler material blocking a blood vessel; because the blood vessels of the forehead and brow area are connected to those around the eye, this area requires particular care. If increasing pain, whitening or purplish discolouration of the skin, a vision disturbance, or difficulty swallowing or breathing is noticed, a doctor should be contacted immediately.
