Dermal fillers are injectable gels made of hyaluronic acid. This substance naturally occurs in the body. It helps keep the skin plump and hydrated. Dermal fillers can help augment features such as the chin, cheeks, and lips. They also fill in hollow areas under the eyes and temples.

Resilient hyaluronic acid or RHA are dermal fillers designed to mimic the flexibility and natural movement of the skin, resulting in a more natural-looking outcome. Patented cross-linking technology makes RHA fillers. It allows the hyaluronic acid molecules to move and adapt to the facial experience. As it does, it creates a more dynamic look.

RHA fillers come in three different formulas—RHA 2, RHA 3, and RHA 4. RHA 2 treats fine lines and wrinkles. RHA 3 treats deeper lines and folds. RHA 4 is the thickest formula and helps in areas that require more volume, such as the cheeks.

Galderma fillers include Restylane®, Emervel®, and Sculptra®. Restylane treats moderate to severe wrinkles and folds. Emervel creates a more natural-looking result with less bruising and swelling.

Sculptra stimulates collagen production in the skin. It is different from other fillers that provide immediate results. Sculptra requires multiple treatments over several months to achieve the desired effect. However, the results are longer-lasting and can last up to two years.

Allergan fillers include Juvéderm®, Voluma®, and Volbella®. Juvéderm treats moderate to severe folds and wrinkles. Voluma adds volume to the cheeks. It can last up to two years. Volbella has a thinner consistency than the other fillers. It is for the lips and gives a more natural-looking result.

Dermal fillers are generally considered safe. However, there are some risks and negative effects to be aware of. These include redness, bruising, and swelling in the injection site. These usually subside within a few days. More severe side effects, such as allergic reactions or infections, can occur in rare cases.

Choose a qualified and skilled injector to minimize the risk of complications. Disclose any medical conditions or medications you are taking to your injector before treatment. Dermal fillers are not ideal for pregnant or breastfeeding women.

The longevity of dermal fillers varies based on the formula and brand used. Most fillers can last six months to two years before needing a touch-up treatment. Your metabolism and lifestyle factors, such as sun exposure and smoking, also determine your longevity.

Follow a good skincare routine and avoid excessive sun exposure. Combining dermal fillers with other nonsurgical treatments, such as laser therapy or Botox, can give optimal results.
