Development and Validation of a Novel Holistic Skin Quality Assessment Scale.

Abstract

Background: Radiant skin is a common patient request and the result of multiple contributing factors. Currently, there is no standardized methodological approach that facilitates assessment of skin quality from a holistic perspective.

Aim: To develop a holistic methodological process to assess skin quality using a scale that helps identify treatment priorities, facilitates conversation with the subject, and helps manage expectations, supports long-term treatment plans, and tracks treatment progress over time.

Methods: Ten global experts (dermatologists and esthetic physicians) identified the main measurable aspects that contribute to skin quality, and these were combined to form the Skin Quality Assessment Scale (SQS). The scale comprises four overarching skin quality domains containing nine measurable aspects: texture (pores, lines, scars); discoloration (redness, pigmentation, dullness); firmness (laxity); and hydro-lipid balance (oiliness, dryness). Each aspect is graded on a 4-point severity scale (0 = none to 3 = severe). The SQS was validated by a large group of practicing clinicians.

Results: Practicing clinicians (> 40, 78% dermatologists) were surveyed; prior to reviewing the scale, 67% did not use any scale but 81% believed a holistic SQS was needed. After reviewing the scale, 100% agreed the scale provides a holistic assessment of skin quality. In addition, 95% agreed the scale helps assess all key aspects of skin quality with subjects and 98% deemed it valuable for their clinic.

Conclusions: The SQS represents a holistic assessment tool that engages with and manages subjects' expectations, identifies treatment priorities, creates a long-term treatment plan, and visualizes the skin quality improvement over time.
