After several years working as a senior executive in the entertainment industry, Dr. Yale Popowich started a private plastic surgery practice that he operated for more than a decade. As the principal of the practice, Dr. Yale Popowich advised his clients on cosmetic and anti-aging treatments, such as dermal fillers.

Made from hyaluronic acid, a type of sugar produced naturally by the body that declines with a person’s age, dermal fillers can be effective against several signs of aging, including wrinkles, sunken skin, and scars. On average, the youthful, smoothing effect of a single filler treatment can last four months to two years, depending on the brand and procedure.

Some types of fillers can also be used to plump the lips and cheeks. In either procedure, the results are temporary since the body safely absorbs hyaluronic acid. However, to avoid complications, women who are breastfeeding or individuals recently recovered from sinusitis should not undergo dermal filler procedures.
