What Is It?

The Skin Quality Index is a streamlined vocabulary, rooted in science and developed in collaboration with healthcare providers and patients, to simplify discussions around skin quality concerns, treatments, and outcomes.This standardized, science-backed resource provides a unified language to describe and address skin concerns by fostering clarity, empowering patients, and enabling providers to make more precise recommendations to support positive patient outcomes.

The Research

Skin quality has become increasingly popular as an aesthetic category, and yet patients and providers often utilize different terminology when describing skin quality attributes or concerns, which could create confusion. Ultimately, the term "skin quality" itself functions as a non-specific umbrella phrase or catch-all, proving an imprecise medical descriptor. Its true meaning is highly individualized, encompassing a unique set of concerns for each patient, and relying on such a broad term could hinder accurate assessment, consultations and treatment recommendations and negatively impact treatment outcomes. To address this problem, Allergan Aesthetics conducted a three-phased research approach to develop a patient-provider communication tool with insights from both healthcare providers (HCPs) and patients, to transition "skin quality" from a vague concept to one with a more precise and personal understanding.

Study Results

Visible Color

Purely visible by the eye

Topographical

Perceived by touch or feel

Hydration and Sebum*/Oil

Change in skin moisture or oiliness

Mechanical

How skin moves with physical manipulation or deformation

*Sebum is an oily substance produced by sebaceous glands in the skin, which helps to lubricate and protect the skin and hair.

More About the Methodology

The research behind the Skin Quality Index was split into three phases:

1

Phase 1

Phase 1

A scientific literature review analyzed more than 900 articles comprising 4,668 research observations published over 20+ years, making it the largest and first of its kind for skin quality terminology. As a result, a framework of terms for frequently assessed skin quality attributes was proposed.

2

Phase 2

Phase 2

The framework was refined based on feedback from global aesthetic HCPs, resulting in 15 consensus terms distributed across 4 domains.

3

Phase 3

Phase 3

Patient focus groups were held to understand if the terminology was impacted by age or gender. Online surveys of over 200 aesthetic providers and over 1,000 patients were utilized to assess if the terminology was impacted by provider expertise or conversational partner (patient-patient, HCP-to-patient, or HCP-to-HCP). Ultimately, the results showed the need for a consistent vocabulary, and the 15 consensus terms distributed across 4 domains remained.

More About the 4 Categories

Stemming from this research, The Skin Quality Index is organized into 4 core categories around the way skin can change.

The Skin Quality Index

The Index features 15 terms and definitions that fall under the 4 core categories. These terms aim to enhance understanding and decision-making from patient consultation to treatment. Use these terms to facilitate better communications around skin quality concerns.

Improving Outcomes

The Skin Quality Index establishes a common language among the communities below.

Patients:

The goal is to empower patients to express concerns clearly through standardized terms, allowing them to take an active role in their skincare.

Providers:

The goal is to equip providers with the right tools to make precise, personalized recommendations from consultation to treatment and improve communications with patients.

Industry:

The goal is to streamline communications when approaching product evaluations and outcomes around skin quality. The Skin Quality Index is a tool that will support health authorities and regulatory bodies in evaluating indications for products related to skin quality, resulting in more efficacious treatments on the market.

From improving consultations to enhancing industry practices, the Skin Quality Index sets a new standard in skin health, fostering better patient outcomes and satisfaction.
