My lips are 5 cm long and 2 cm thick. are they considered as medium or full lips?

There is
no numerical measurement that would categorize lips as "medium or
full".  I suggest you put the ruler down and ask yourself do you
like the appearance of your lips. If not, what is it about them you would like
to change? If you can not specify what you do not like about them but feel they
could look better than see a dermatologist or plastic surgeon in
consultation. They will examine your lips in the context of your whole face and
should be able to guide you as to what options you might have in making an improvement.

Hope this helps

 Hi, I have performed many lip augmentation procedures using dermal fillers or lip implants for over 30 years. Non smiling photos of your upper lips would help in the evaluation.   Following the beauty principles outlined in my book on face and body beauty, the upper lip should be approximately 75 % the size of the lower lip for the lips to appear balanced. The upper lip can be augmented using a dermal filler or a Permalip implant.





Dermal filers and lip implants offer far more reliable volume to augment the lips than permanent fillers or fat injections that are also associated with increased, unwanted, side effects.







Hope this helps.
