Dermal filler
A substance injected into the dermis to give the skin a fuller look. The filler is made from a soft material that is injected into unwanted folds, creases, and wrinkles ot make them less visible invisible. The effects may last 3 to 4 months or be permanent depending on the type of filler used.

Fillers are categorized by their ingredients ad the duration of their effects. The major temporary fillers consist of collagen, hyaluronic acid (Juvederm, Restylane, Perlane), hydroxylapatite (Radiesse), or poly-L-lactic acid (Sculptra). Permanent fillers are made of methyl methacrylate and silicone. Fillers can be used to augment the lip lines and the lips themselves, to fill creases and lines around the mouth, and to address the volume loss that naturally occurs with aging.

Dermatitis

A general term used to describe inflamed skin. There can be many causes of dermatitis, such as an allergic reaction or atopic dermatitis. Dermatitis can be short-term ("acute") or long-term ("chronic"). Acute dermatitis causes the skin to appear red, blistered or swollen. Chronic dermatitis causes the skin to appear thickened, rough, and darker than the surrounding skin. Some may also use the term “eczema” to refer to dermatitis.
