Forehead lines in a teenager: what to know

Some teenagers notice horizontal creases when raising the eyebrows, concentrating, or using expressive facial movements. Dryness, eczema, acne products, frequent sun exposure, and repeated irritation can make creases look sharper. Facial anatomy also varies, so visible lines do not by themselves show that skin is ageing unusually.

Look for accompanying clues: itch, scale, redness, burning, pimples, or a mark that stays in one place. General information about [Wrinkles](/symptoms/wrinkles/) can help you describe the pattern during an appointment.

Use a gentle cleanser, a plain moisturiser, and daily sunscreen. Introduce acne or exfoliating products slowly, and stop a product that causes burning, swelling, or persistent redness. Avoid tanning and do not pick at bumps or flaky areas. A parent or guardian can help arrange a dermatologist visit if the concern persists or affects confidence.

Injectable cosmetic treatment is not a first response for a teenager. If it is ever discussed, the clinician should consider age, consent, medical history, facial development, and the reason for the concern. [Botox](/treatments/injectables/botulinum-toxin-injection/) is a treatment page, not a recommendation for self-treatment.

Book a review for a persistent itchy or scaly patch, painful swelling, a rapidly changing spot, or lines that appeared with a new medication or skin reaction. Seek urgent help for facial swelling with breathing difficulty, eye swelling with vision change, or signs of infection such as fever and spreading warmth.

Ask whether the lines are expression creases or part of an irritated skin condition, which products to pause, how to protect the area outdoors, and what follow-up would be appropriate if the appearance changes.
