Dermal fillers or soft tissue fillers are substances designed to be injected beneath the surface of the skin to add volume and fullness to area that have lost volume, usually as a natural result of ageing. There are different types of dermal fillers made by different pharmaceutical companies. Most dermal fillers contain hyaluronic acid, a natural compound that aids in the production of collagen and elastin.
Different types of dermal fillers are designed to treat varying signs of aging. Depending on the filler selected, they may plump up thinning lips, enhance or fill in shallow areas on the face, decrease or remove the shadow or wrinkle under the eyes caused by the lower eyelid, fill in or soften the look of recessed scars and fill in or soften static wrinkles, especially on the lower face.
Dermal fillers are considered to be safe in professional hands, but side effects can occur. The more common problems include: skin rash, itching, or pimple-like eruptions, redness, bruising, bleeding, or swelling, undesirable appearance, such as asymmetry, lumps, or overcorrection of wrinkles, skin damage that causes a wound, infection, or scarring, ability to feel the filler substance under the skin, blindness or other vision problems and death of skin cells due to loss of blood flow to the area.
