Crinkle lines (aka atrophic crinkling rhytids) are associated with the beginning signs of aging. They’re on the shallow side and often appear as fine lines on the forehead that vanish when the skin is stretched. Along with intrinsic (natural) aging, lifestyle habits affect how early on these wrinkles start to appear.
Permanent Elastotic Creases
Those with a pale complexion who have spent a lot of time out in the sun (likely, without adequate protection) are prone to getting this type of wrinkle. They appear where the skin naturally creases (think cheeks, lips, the bottom of the neck), and unlike crinkle lines, these are deep wrinkles.
Dynamic Expression Lines
As the name suggests, these lines are caused by our repeated facial expressions and the loss of elasticity. These wrinkles can appear as crow’s feet, laugh lines, forehead creases, or a combination thereof. Some folks embrace these lines as they are like a snapshot into their personality.
The skin loses 1% of its collagen each year as we age — somewhere around 25 years — so with continued loss of elasticity, the skin eventually begins to sag because it’s no longer attached to the latent fat muscle underneath. These “folds” are what are known as jowls around the neck and chin areas.
