Factors influencing facial aging and skincare after age 40

Facial aging often becomes more noticeable after age 40 due to a combination of biological and hormonal factors. Experts note that the loss of facial definition, often referred to as a ‘melted face’ appearance, is driven by a reduction in bone density, changes in fat compartments, and a progressive decline in collagen and elastin production.

Hormonal shifts, particularly the drop in estrogen during the transition to menopause, play a significant role by making skin thinner, less hydrated, and less capable of producing collagen. Rapid weight loss can also exacerbate the loss of facial volume and support.

In terms of skincare, dermatologists distinguish between the roles of collagen and retinol for mature skin. While collagen-based products primarily assist with hydration and skin appearance, retinol has more consistent evidence for treating fine lines, irregular texture, and photoaging. Experts emphasize that hydration and sun protection remain essential components of a skincare routine.
