Dermal Fillers
Dermal fillers are FDA-approved and used for the cosmetic treatment of fine facial lines, wrinkles, and folds. Injectable dermal fillers can also be used to plump or add volume to thin lips. Many patients searching for lip fillers in Portland that turn to us for expert care. Dermal fillers are composed of hyaluronic acid, a naturally occurring substance found in every living cell. Fillers contain synthetic gel forms of hyaluronic acid derived from non-animal sources and are highly compatible with the body. When the gel is injected, it acts like an inflated cushion to support facial structures and tissues that may have lost volume or elasticity with normal aging.
Hyaluronic acid also brings water to the surface of the skin to keep it looking fresh and supple. The gel is injected into the skin through a fine-gauge needle at the site of unwanted lines and wrinkles. Whether you’re interested in lip injections in Portland Oregon or cheek enhancement, safety is key. While dermal fillers are generally safe, dermal filler treatments should be performed by a professional to avoid complications and serious side effects at the injection site.
Here at Knott Street Dermatology, we offer the full line of Juvéderm and Restylane HA fillers perfect for those looking for lip fillers in Portland OR and personalized results.

HYALURONIC ACID FILLERS
Hyaluronic acid fillers are temporary dermal fillers that restore skin moisture and diminish signs of aging. Its main ingredient, hyaluronic acid (HA), is a primary component of the skin and is responsible for that plump and hydrated look. Benefits of HA fillers include anti-aging, moisturizing, anti-wrinkle, restoring skin elasticity, and treating eczema and redness. These are ideal for those seeking lip injections in Portland with natural results. HA fillers are safe and allergic reactions are rare with this type of filler because hyaluronic acid is naturally produced by the skin.
Hyaluronic acid fillers can last up to 18–24 months or longer. Like any cosmetic procedure, there is no guarantee of complete satisfaction, or that wrinkles and folds will disappear completely. Additional treatments may be required to achieve desired results, and visible outcomes will vary per patient. To maintain the desired effect, we recommend follow-up treatments before the effects of the last treatment wear off. Whether you’re looking for fillers in Portland Oregon or subtle lip volume, we are here to help.
