The aging process is characterized by a progressive reduction in the body's ability to operate. Changes in physical appearance, physiological changes, and functional deterioration can be used to quantify aging. It is not fully understood what causes aging, although it is believed to be a combination of genetic, environmental, and lifestyle factors. Common impacts of aging include the development of wrinkles, gray hair, a loss of muscle mass, and a drop in cognitive capacities. Nevertheless, aging is also accompanied by a heightened sense of self-awareness and perspective.
The aging process in dermatology is defined by changes in the skin, hair, and nails. Among the most significant changes that occur with age are as follows: The skin loses suppleness and collagen as it ages, causing wrinkles and drooping. Age spots, also known as liver spots or solar lentigines, are flat, pigmented regions that can occur on sun-exposed skin. The ability of the skin to retain moisture decreases with age, resulting in dryness and irritation. Our skin thins, becomes more brittle, and is more prone to injury. Aging causes the skin to become more delicate and susceptible to bruising. With age, hair follicles diminish and generate hair that is thinner, shorter, and less pigmented, resulting in hair loss, graying, and reduced hair density. The skin's barrier function declines, making it more vulnerable to environmental harm and infection.
Photoaging is a form of aging caused by exposure to ultraviolet (UV) light from the sun or other sources like tanning beds. UV light can damage skin cells' DNA, resulting in mutations and an increased risk of skin cancer. It can also alter the structure and function of the skin, leading to the appearance of wrinkles, age spots, and other indications of aging. UV radiation from the sun damages the skin primarily by creating reactive oxygen species (ROS), which induce inflammation, collagen and elastin breakdown, and melanin synthesis, resulting in structural and functional changes to the skin. As well as using sunscreen, wearing protective clothes, and avoiding tanning beds, preventing photoaging involves decreasing overall exposure to UV radiation. In addition, the use of skincare products containing antioxidants, retinoids, and other anti-aging components can assist in delaying the onset of photoaging.
When we make facial expressions such as smiling, frowning, or lifting our eyebrows, our skin develops dynamic wrinkles, also known as expression lines. These wrinkles are generated by the contraction of the underlying muscles, and they are typically most pronounced in parts of the face that are frequently used for facial expressions, such as the forehead, around the eyes, and around the lips.
Loss of volume is a prevalent characteristic of aging that affects the face and the rest of the body. It is characterized by a loss of fat and other tissues, resulting in a drooping or hollowing appearance. In dermatology, volume loss is most typically observed in the face and can result in a loss of facial features, hollowing around the eyes and mouth, and sunken cheeks.
Skin sagging, also known as skin laxity, is a typical characteristic of aging caused by a decrease in the skin's collagen and elastin content. Collagen and elastin are proteins that give the skin structure and support, and their depletion results in a loss of elasticity and firmness. The face, neck, and arms are the most prevalent areas of the body where sagging skin is observed.
Resorption of the facial bones is the gradual loss of density and mass of the facial bones over time. This can alter the face's shape and features, resulting in a more aged, sunken, or hollow appearance. In more severe cases of facial bone resorption, jaw reconstruction surgery may be undertaken. Facial bone resorption can be prevented by maintaining a healthy lifestyle and diet, consuming enough calcium and vitamin D, and avoiding smoking and consuming alcohol in moderation.

Rhinoplasty is a cosmetic surgery procedure designed to enhance the shape and proportion of the nose, often to achieve a more balanced and natural facial appearance. One of the commonly used materials in rhinoplasty is auricular cartilage, which is the cartilage harvested from the back of the ear. It is favored for its flexibility, biocompatibility, and natural integration with nasal tissue when taken from the patient’s own body.

It is widely recognized that nowadays, people are increasingly interested in keeping pets as companions. This trend is evident from the growing expansion of pet-related businesses (Zhang et al., 2022). One contributing factor to this rise in pet ownership may be the positive effects pets have on both physical and mental health. Studies have reported that having a pet can help reduce stress and positively impact human health in various aspects (McConnell et al., 2011). For example, pet ownership has been linked to increased physical activity (Li et al., 2024) and enhanced social interaction, which contributes to a better quality of life (Antonscopoulos & Pyctyl, 2014).
Facelift surgery is a cosmetic procedure aimed at rejuvenating the face by tightening sagging skin and improving facial contours. It helps restore a more youthful appearance by addressing signs of aging such as drooping skin and loss of firmness. Surgeons select the most appropriate surgical technique based on the condition of each patient's skin and individual aesthetic goals.
