For a younger, firmer & natural looking skin, Dr.Hilmi uses Sculptra Bio stimulation for collagen boosting in the skin, for a radiant & youthful glow.

Since it works with your body's own collagen to help it produce more, it helps the overall condition of the skin to improve itself.

Collagen Is Key

A Source Of Smooth Skin

Collagen is a fibrous protein in the deep dermis that gives skin structure and supports the functions of elastin and hyaluronic acid (HA), which helps maintain the skin's shape, while keeping it smooth and hydrated. A healthy supply of collagen makes for a more youthful-looking complexion.

How Much Collagen Have You Lost?


Sculptra® uses poly-L-lactic acid to help rebuild collagen for a more youthful-looking appearance that can last up to two years*

*Individual results and treatment regimens may vary. Clinical trial ended at 96 weeks (2 years).

How will you look like after Sculptra?

Immediately after your treatment, it may appear that Sculptra filled in the area because of swelling from the injections and water used to dilute Sculptra. In a few days, however, the swelling goes down and you will likely look just as you did before the treatment.

Does Sculptra Look Fake?

Because Sculptra merely induces a natural process to your body, the results will never look fake or dramatic. Just smooth, healthy-looking skin, as if the layers of your skin never got tired of actively producing collagen as you age! Sculptra also doesn't focus on just one tiny area of skin.
