What Really Causes Under-Eye Bags and Sagging Skin | Tanuj Nakra, M.D. & Suzan Obagi, M.D.

Summary

This insightful discussion explores the biology of facial aging, focusing on the role of bone loss, fat atrophy, and hormonal changes that significantly affect the face, especially in women. It emphasizes how these changes lead to visible signs of aging, such as sagging skin, hollowness around the eyes, and a loss of definition in the jawline. The conversation highlights the unique nature of facial fat and its response to stress, aging, and weight changes. Hormone replacement therapy and lifestyle factors are also discussed as important considerations in mitigating aging effects.

Takeaways

• 😀 The aging face, particularly from the neck up, involves changes in skin, fat, muscle, and bone structure.
• 😀 Fat compartments in the face, which provide volume and padding, atrophy over time, leading to the appearance of a tired or aged look.
• 😀 Bone loss around the eyes and other facial areas contributes to the appearance of aging, as the bones shrink and the face loses its structural scaffolding.
• 😀 Women tend to experience more dramatic facial aging, particularly from their 50s, due to a sharper decline in bone structure and fat volume compared to men.
• 😀 Hormonal changes, especially in women, influence the aging process, including the loss of bone density in the face, similar to changes in bone density in other parts of the body like the hips.
• 😀 Hormone replacement therapy, particularly maintaining estrogen levels, can help maintain bone health and slow the aging process in women.
• 😀 Stress, including hormonal stress, plays a significant role in facial aging. Chronic stress and cortisol levels can contribute to both fat loss and skin aging in the face.
• 😀 The aging process in the face is not fully understood biologically, but it's clear that fat compartments in the face are metabolically different from other areas of the body.
• 😀 There is a phenomenon where women, particularly after pregnancy, experience significant changes in their facial fat, leading to a thinner face despite maintaining a similar body weight.
• 😀 Lifestyle factors, such as stress and skin care, have a profound impact on the appearance of aging. Wealthier or less stressed individuals may show fewer signs of aging compared to those with more challenging lives.

Q & A

Why do people often look tired as they age?

As people age, facial changes like bone loss, fat atrophy, and muscle thinning can contribute to a tired appearance. Specifically, fat compartments that help add volume and cushion the face shrink, and bones like the jaw and cheekbones also lose volume, causing skin to sag.

What is the connection between aging in the face and hormone levels, especially in women?

Hormonal changes, particularly the decline of estrogen in women during menopause, accelerate bone loss in the face, leading to structural changes. This is why women often experience facial aging much faster than men, especially in their 50s and beyond.

How does bone density change as we age, and how does this affect the appearance of the face?

Both men and women experience a decline in bone density from their 20s onward, but this decline accelerates for women around menopause. Bone loss around the eyes, cheekbones, and jaw can cause the face to lose its definition, leading to a more hollow or sagging appearance.

What are some early signs of facial aging that people notice?

One of the earliest signs is the area around the eyes. As fat atrophies and bone density decreases, the skin around the eyes can appear more hollow, and people may notice deeper lines or undereye bags.

Why do women tend to age faster in the face than men?

Women experience a rapid decline in bone and fat volume in the face, especially after menopause. This can cause more noticeable changes in facial appearance compared to men, whose facial aging tends to be slower and more gradual.

How does weight gain and loss affect facial fat?

Facial fat is unique in that it doesn’t always follow the same pattern as fat in other areas of the body. Weight loss often leads to a thinning of the face, and even if overall body weight remains stable, the face can appear thinner, especially after multiple cycles of weight gain and loss.

What happens to facial fat compartments as we age?

Most facial fat compartments atrophy over time, causing the face to lose volume and appear more skeletal. Some areas, like the nasolabial fat compartment, may increase in size, but overall, the face loses its youthful fullness.

What role does stress play in the aging process of the face?

Chronic stress increases cortisol levels, which can have a catabolic effect on facial fat, leading to more volume loss. Stress also accelerates skin aging by reducing elasticity and collagen, making the face appear older.

Is there a biological reason for the atrophy of facial fat over time?

The exact biological mechanisms behind facial fat atrophy are still not fully understood. However, it's believed that stress, hormonal changes, and overall metabolic shifts contribute to the decline in fat volume in the face.

How do lifestyle factors influence facial aging?

Lifestyle factors such as stress, sun exposure, and poor skincare habits can accelerate facial aging. People who live more stressful lives or have a history of poor skincare may experience more rapid aging in their facial appearance, as seen in the example of two patients with vastly different lifestyles.
