Background The use of validated scales is still considered the gold standard in evaluating the severity of an aesthetic facial condition. Objectives The objective of this investigation was to create and validate 5-point photo numeric scales which assess perioral lines and marionette lines. Methods A medical team created two different novel 5-point photonumeric scale for the assessment of perioral lines and marionette lines. Eleven international raters were involved in the digital validation, while 4 raters performed a live validation. Results For the Croma Static Perioral Lines-Assessment Scale digital inter-rater ICCs were 0.88 [95% CI: 0.85-0.91] in the first rating and 0.87 [0.83-0.90] in the second rating. The digital intra-rater ICCs were 0.90 [95% CI: 0.87-0.92]. In the live rating, the inter-rater ICCs were 0.89 [95% CI: 0.85-0.93] in the first rating and 0.91 [95% CI: 0.87-0.93] in the second rating with an intra-rater ICC of 0.91 [95% CI: 0.88-0.95]. For the Croma Marionette Lines-Assessment scale the digital rating inter-rater ICCs were 0.85 [95% CI: 0.81-0.89] in the first rating and 0.87 [95% CI: 0.84-0.90] in the second rating with an intra-rater ICC of 0.89 [95% CI: 0.88-0.91]. In the live rating, the inter-rater ICCs were 0.73 [95% CI: 0.54-0.83] in the first rating and 0.79 [95% CI: 0.65-0.87] in the second rating with an intra-rater ICC of 0.88 [95% CI: 0.83-0.94]. Conclusions It is to be concluded that the Croma Static Perioral Lines-Assessment Scale and the Croma Marionette Lines-Assessment Scale have exceptional inter- and intra-rater agreements to be justifiably used in the clinical and study setting for all ethnic groups.

Background A scarcity of scales which assess platysmal bands, wrinkles in the décolleté, and horizontal necklines in the digital and live setting exist. Objectives The objective of this investigation was to create and validate 5-point photo numeric scales which assess horizontal necklines, platysmal bands and wrinkles in the décolleté. Methods A medical team created 3 different novel 5-point photonumeric scale for the assessment of horizontal necklines, platysmal bands and décolleté wrinkling. Eleven international raters were involved in the digital validation, while 4 raters performed a live validation. Results The Croma Horizontal Neck Line - Assessment Scale showed substantial inter-rater agreement and almost perfect intra-rater agreement in the digital and live validations. The Croma Platysmal Bands-Assessment Scale showed substantial intra-rater agreement in both, digital and live validations. For the décolleté, a static and a dynamic scale was created and validated. The Croma Static Décolleté Wrinkling-Assessment Scale showed substantial and almost perfect inter-rater agreement in the digital validation and live-validation, respectively, while the intra-rater agreement was in both almost perfect. The Croma Dynamic Décolleté Wrinkling-Assessment Scale showed almost perfect agreement in both validation settings for both, inter-and intra-rater agreement. Conclusions The Croma Horizontal Neck Line - Assessment Scale, the Croma Static and Dynamic Décolleté Wrinkling-Assessment Scales have sufficient inter and intrarater agreements to be justifiably used in the clinical and study setting.
