Jowls, characterized by lax, drooping facial skin along the jawline and chin, typically become noticeable in the late 30s or 40s, with prominence increasing in the 50s and 60s, according to Dr. Mona Gohara, a board-certified dermatologist and associate clinical professor of dermatology at Yale School of Medicine. The appearance of jowls is influenced by genetics, which affect skin thickness, bone structure, fat distribution, and collagen quality.

As people age, the skin's internal support system—composed of collagen, elastin, fat, bone, and muscle—begins to weaken. Dr. Gohara highlights that the gradual loss of collagen and elastin contributes to skin laxity, which ultimately leads to jowls. Collagen provides structural support, while elastin helps the skin regain its shape. This deterioration begins as early as the mid-20s and accelerates during menopause, primarily due to decreasing estrogen levels.
UV exposure significantly contributes to visible aging and the breakdown of collagen and elastin, making sun protection crucial. Additionally, loss of jawbone density and shifts in facial fat distribution can impact the skin's appearance.
Dr. Gohara emphasizes several preventive measures that can help maintain skin firmness and delay the onset of jowls. A healthy lifestyle, including sufficient sleep, a nutritious diet, and not smoking, is essential for preserving collagen. An effective skincare routine should include daily sunscreen—vital for protecting the skin against sun damage—and antioxidants like vitamin C and niacinamide to combat environmental stressors.
Retinol, derived from vitamin A, is a proven topical treatment for skin laxity, while peptides can signal cells to produce more collagen and elastin. To minimize irritation from retinol, Dr. Gohara recommends using a layer of a peptide-rich barrier cream.
For those seeking more noticeable results, noninvasive cosmetic procedures such as laser resurfacing, radiofrequency, or focused ultrasound can stimulate collagen and elastin production, although surgical options provide more dramatic results.
In conclusion, while complete prevention of jowls is not possible due to the natural aging process, proactive skincare and healthy habits can significantly delay their appearance and improve skin firmness.
