Wrinkle Severity Rating Scale (WSRS).

Grade	Severity	Description
1	Absent	No visible nasolabial fold, continuous skin line
2	Mild	Shallow but visible nasolabial fold with a slight indentation, minor facial feature, implant is expected to produce a slight improvement in appearance
3	Moderate	Moderately deep nasolabial fold, clear facial feature visible at normal appearance but not when stretched, excellent correction is expected from injectable implant
4	Severe	Very long and deep nasolabial fold, prominent facial feature, <2 mm visible fold when stretched, significant improvement is expected from injectable implant
5	Extreme	Extremely deep and long nasolabial fold, detrimental to facial appearance, 2–4 mm visible V-shaped fold when stretched, unlikely to have satisfactory correction with injectable implant alone
