Upper lip wrinkles get started with the loosening of the facial skin. This is again a factor of the aging and is generally caused by the fat cells beneath the skin get accumulated in a manner such that the skin appears very much wrinkled. Now that said there are several ways by which you can very easily cause these lips to look fuller younger and firm.
People who smoke get these upper lip wrinkles. Smoking causes the skin to wrinkle because of the effect of lessening of the Vitamin C and lessening of moisture within the body. These are also known as smoker’s lines.
Another major cause is the Exposure to sun and it can cause massive wrinkles.
There is a belief that people who have hair on the upper lip they also get wrinkles when they go for lip waxing or threading. That is why in general it is advisable to go in for the permanent hair removal. You can get the laser permanent hair removal done to make sure that you have the hair permanently gone.

Two major things available in the market are
Botox Injections
Wrinkle Fillers
Both of these when applied can give a wrinkle free appearance as the loose skin has been tightened by the fact that there is material that has been injected into the upper lip.
Another category of wrinkles are the perioral wrinkles which will be there around the mouth and the lips. Now these can be treated using a variety of methods like the Laser Skin resurfacing. Laser Skin resurfacing is permanent solution as opposed to the fillers. Then there are Restylane treatments available to counter the wrinkles temporarily.
Best Anti wrinkle lip creams should be the creams that have retinol in them. It is suggested that you use them in the morning and later in the night when you are about to go to bed.
As far as exercises go there are a number of exercises to get rid of upper lines on the lip and I will be detailing that in some later post.
