There are at least 12 "expression" muscles that are attached to the dermis are around the lips. Besides frying that upper lip drying it out and poisoning it; you've trained the muscles to contract further wrinkling and creasing the skin.
What to do? Things that can help from your esthetician:
- light microdermabrasion
- microcurrent
- hydrating treatments that include hyaluronic acid
- An SPF30 sunscreen with a physical block (zinc oxide and/or titanium dioxide)
- a clear waxy lip liner can help to keep lipstick from bleeding up the creases
To just have the lip treated would run around $25 - $50 each treatment plus take home products to continue the treatment.
Things that can help for more severe cases:
- hyaluronic acid fillers (Restylane, Juvederm, etc.)
Dermal fillers run about $400 per treatment.
