What Causes Forehead Lines and Wrinkles?
People tend to assume wrinkles across the forehead are stress induced-they’re really the combined results of sun exposure, muscle movement and diminished collagen.
Collagen is a protein allows skin to stay hydrated and elastic, and as its production slows with age the skin is left thinner, weaker and more prone to wrinkles forming after years of repeated facial movements.
Wrinkles appear whenever muscles move in your forehead as you frown, squint or look surprised. As time goes by and skin ages, these wrinkles settle in permanently and are visible even when the face is relaxed.
The aging process varies according to genetics and lifestyle-smokers always end up with dry skin-and wrinkles can set in from your late 20’s onwards.
