Here are two ways in which dermal filler injections can make a person look younger.
Dermal filler can add facial volume that a person may have lost during the ageing process
There are certain parts of a person's face, such as their cheeks and undereye area, that tend to lose volume when they get older. This is caused by a combination of fat loss and a reduction in skin elasticity, which can lead to these areas flattening out and the skin sagging. Flat and slightly gaunt-looking cheeks can make a person look older because most people associate plump cheeks with youthfulness.
Likewise, hollowness in the undereye area is often considered to be a sign of tiredness and ageing, whilst fullness and smoothness in this area are associated with youth and being well-rested. Dermal filler can disguise these signs of ageing, by adding volume to these parts of the face. This volume created by the filler will fill the sagging skin so that its lack of elasticity is not as noticeable, and it will also give the treated facial areas a youthful plumpness. Hyaluronic acid is the most common filler used for the treatment of volume loss in these areas.
Dermal filler can smooth out wrinkles and fine lines
Most people develop wrinkles and fine lines as they age. These are caused by things like sun damage and by people repeatedly making certain wrinkle-forming facial expressions when they talk. Whilst some people who want to minimise these lines will opt for a treatment like Botox, which temporarily paralyses the muscles involved in the formation of certain wrinkles, many others prefer to get dermal fillers for this issue.
Dermal fillers can be injected directly into the wrinkles or fine lines on a person's face and used to plump up these indentations. This method of wrinkle-minimisation is most frequently used for lines in areas such as the nasolabial folds and for marionette lines. It is less common for dermal fillers to be used for the wrinkles that form on the forehead. People who opt for dermal fillers to treat their facial wrinkles, instead of Botox, usually do so because they want to be able to use all of their facial muscles and make any facial expressions they wish to. Much like Botox, dermal filler is a temporary wrinkle and fine-line treatment, as the filler will usually be absorbed by the body within a few months of the procedure.
