While you’ve probably heard of the Fitzpatrick Skin Typing assessment, you may not have heard of another skin typing tool known as the Glogau Classifcation for Photoageing, or the Glogau Wrinkle Scale. This photodamage classification system was developed by Dr. Richard Glogau and is now being referenced world wide by dermatologists and plastic surgeons.
As skin therapists, it is crucial to understand the signs of aging on the skin and to be able to effectively evaluate and treat these conditions. One tool that can be extremely helpful in this process is the Glogau Wrinkle Scale. In this post, we will discuss the Glogau Wrinkle Scale and the effects of photoaging on the skin.
The Glogau Wrinkle Scale is a four-level scale that is used to evaluate the severity of wrinkles and fine lines on the face. Level 1 indicates minimal wrinkles, while Level 4 indicates severe wrinkles and deep folds in the skin. This scale is an important tool in the evaluation of photoaging, as it provides a visual representation of the severity of the aging process.

Photoaging is a type of aging that is caused by prolonged exposure to the sun’s harmful ultraviolet (UV) rays. UV radiation from the sun can penetrate the skin’s surface and damage the underlying structures, including the collagen and elastin fibers that provide support and elasticity. This damage leads to the development of fine lines, wrinkles, and age spots on the skin, as well as a loss of firmness and elasticity.
As skin therapists, it is important to educate our clients on the importance of protecting their skin from the damaging effects of photoaging. This includes using a broad-spectrum sunscreen with an SPF of at least 30 every day, wearing protective clothing, and seeking shade during peak sun hours. In addition, incorporating a skin care regimen that includes antioxidants, such as vitamin C, can help to protect the skin and support its natural rejuvenation process.
When evaluating a client’s skin, it can be helpful to use tools such as the Glogau Wrinkle Scale to accurately assess the severity of their wrinkles and fine lines. This information can then be used to develop a personalized treatment plan that may include a combination of topical treatments, such as retinoids or hyaluronic acid, as well as cosmetic procedures, such as microneedling and chemical peels.
- Subjectivity: The scale relies on subjective assessment, and so the results can vary based on the observer and their biases.
- Culture-Dependent: The perception of wrinkles and aging can vary across cultures, making the scale less universal.
- Limited Facial Areas: The scale only covers wrinkles in certain areas of the face, and does not take into account overall skin quality.
- No standardization: There is no universal standard for using the scale, leading to inconsistent results.
- Only for wrinkles: The scale only focuses on wrinkles, and does not assess other signs of aging such as age spots, sagging skin, or hyperpigmentation.
- Injectables: The high prevalence of using Botox and fillers to hide the visible signs of ageing, like wrinkles, can mean that a visual assessment of the skin is highly inaccurate as wrinkles are masked by injectables.
While the Glogau Wrinkle Scale has some limitations, it is nevertheless a valuable tool for professional skin therapists to help clients understand the signs of aging on the skin and develop personalized treatment plans and home care routines. It is best used alongisde other skin typing systems like the Fitzpatrick Scale and tools such as a woods lamp or digital skin analyser to assess our clients current and future photoageing risk factors.
