What should you know about forehead sleep lines?

Pressure from a pillow, a preferred sleeping position, and natural facial movement can temporarily crease the skin. In younger, more elastic skin, these marks may fade after waking. With time, repeated folding, ultraviolet exposure, dryness, and expressive muscle activity can make the grooves linger. [Wrinkles](/symptoms/wrinkles/) is the broader term for these surface lines.

Sleep lines are usually a cosmetic texture concern rather than a sign of illness. Their position, depth, and persistence help a clinician distinguish them from irritation, a rash, or another skin change.

Apply a bland moisturiser and use daily sun protection. Avoid scrubbing the forehead or layering irritating products in an attempt to smooth it quickly. Changing pillow pressure may reduce repeated folding, although sleep position can be difficult to control.

If lines remain visible while your face is relaxed, a qualified clinician may discuss options that reduce muscle activity, including [Botox](/treatments/injectables/botulinum-toxin-injection/). Treatment should be tailored to forehead movement, brow position, skin quality, and your expression goals.

Book an assessment if a line is new and persistent with redness, scaling, itching, pain, bleeding, a lump, or a changing pigmented area. Seek urgent help for sudden facial weakness, vision disturbance, severe headache, or other abrupt neurological symptoms. A stable crease without these features generally allows a routine appointment.

Ask whether the lines are mainly caused by sleep pressure, muscle movement, or skin texture; whether treatment could alter brow movement; what temporary effects to expect; and how to protect the result with skincare.
