The "triangle of the aging face" refers to a concept used in cosmetic and dermatological fields to describe the natural changes that occur in facial appearance as we age. This triangle helps illustrate how aging affects facial structure and symmetry.

Shape and Placement

Base of the Triangle

The base typically aligns with the jawline or the lower face.

Apex of the Triangle: The apex points toward the forehead or hairline.

Changes Over Time

Loss of Volume

As we age, there is a gradual loss of volume in the cheeks and mid-face area. This can lead to a sagging effect, making the face appear more triangular with the base widening.

Skin Sagging

The skin loses elasticity and firmness, causing it to droop, especially around the jawline and lower cheeks.

Fat Redistribution: Fat deposits shift downward, leading to a more pronounced nasolabial fold (the lines running from the nose to the corners of the mouth) and a deeper marionette line (lines running from the corners of the mouth to the chin).

Visual Impact

The triangle’s shape becomes more inverted with aging. In youth, the face tends to have a more heart-shaped or oval appearance with a fuller, youthful contour around the cheeks and a well-defined jawline. As we age, the triangle inverts, making the face look less sculpted and more broad at the bottom with a narrower, less defined upper portion.

Understanding this concept helps in planning cosmetic treatments and understanding the natural aging process, as various interventions can aim to restore or enhance facial volume and contour to counteract these effects.
