Introduction. In European culture, the right shape of the lips is an important attribute of attractiveness. The eyes and lips give character to the face, and many people pay special attention to them because they reveal non-verbal information. Over time, lips, like skin, which are sensitive to external and internal factors, change their appearance. The patient's corrective needs can range from a subtle enhancement of the already appropriate shape and volume to more comprehensive modeling, including the correction of wrinkles, as well as eliminating defects or asymmetries. Aim of the study. The main purpose of the study is to present the basic principles of lip correction surgery. Material and methods. Two women of different ages were subjected to the treatments. The procedure was performed for the first time. Hyaluronic acid of average density 23 mg/ml with lidocaine 0.3% was used for the treatment. Results. Both patients had the effect of rejuvenating the lips, they became fuller and clearer, lip proportions improved. Conclusions. 1. Treatments with the use of hyaluronic acid are an effective method of correcting the shape of the lips. 2. The six-step technique can safely perform treatments on a range of anatomical structures, including the filterium, Cupid's arch, the labia, the border of the labial red, the angles of the mouth, and the columns of the nasal trough. 3. These treatments do not require special preparation of the patient, are well tolerated, allow for a natural, immediate effect and do not require a convalescence period.
