Dr Thierry Michaud, dermatologist and member of the YSL Skin Science team, said: “Many women I treat accept their wrinkles and fine lines but what they cannot accept is their new facial expressions. “Inappropriate expressions are due to a loss of facial volumes: sagging skin, less defined contours, creased neck.

“Neck skin is exposed to sun every day because of low necklines, especially in women, but people are less inclined to think of protecting their necks than their faces,” Dr Rowland Payne. “This is bad news for neck skin as it starts off finer and sun thins it further. Finer skin wrinkles more readily and the fat of the neck may sag.”. In skin, sugar molecules called glycans are responsible for telling the body to produce collagen which makes the skin supple and smooth.

Causes of Sagging Skin. Skin that has lost its spring isn't the result of just one cause. Several factors are likely responsible for making your once supple skin appear tired and droopy. The most common cause of sagging skin is aging. As you age, your skin loses the collagen and elastin, your skin's supportive connective tissue, that make it look soft, plump and youthful. In addition, facial muscles can weaken with age, which takes a toll too.
