Nasolabial folds modeling — literature review

. Nasolabial folds are skin folds that run from both sides of the nose to the corners of the mouth. They are caused by the loss of fat in the dermis, followed by the loss of muscles in the middle part of the face.Aim. The aim of the work is to present contemporary knowledge of materials used for modeling nasolabial folds.Material and Methods. Medical databases PubMed, EBSCO Multiplier, were analyzed by entering the slogans: nasolabial folds, nasolabial folds, hyaluronic acid in nasolabial fold modeling, nasolabial fold correction. Analyzing the literature, data from eleven scientific articles from the last five years (2013–2018) were used.Results. In most articles for modeling nasolabial folds, crosslinked hyaluronic acid was used after prior photographic assessment of skin condition or after anamnesis examination — an interview. From the papers describing the cases, it appears that the applied materials for face aesthetic medicine treatments level the nasolabial folds.Conclusions. The obtained results are ambiguous and studies need to be continued. In the literature, the instrumental evaluation of facial skin was not used before modeling nasolabial folds.
