If you've kept up with pop-culture or beauty trends in the past few years then you know that "Kylie
Jenner lips" are a thing. A really big thing. The Instagram and reality-TV star's noticeably plumper
lips took us by storm back in 2015, and they helped bring the quest for perfection through the use
of cosmetic fillers into the mainstream.

But with so many different types of facial and lip fillers out on the market, it can be difficult to decide
which one is right for you. One way to enhance your lips, smooth out wrinkles, or add fullness to the
face is by using Restylane, an injectable dermal filler.

What is Restylane?

We tapped into the knowledge of Dr. Wafik A. Hanna, who specialises in facial cosmetic surgery at
his Chicagoland practice, to get the low-down on this treatment. According to Dr. Hanna, Restylane
is "the first cosmetic dermal filler made of sugar-based hyaluronic acid. Hyaluronic acid is a natural
substance that already exists in the human body."

How does Restylane work?

Once Restylane is injected into the skin, it can reinvigorate the skin's structure and help stimulate
the production of more collagen.

For qualified candidates, it is used to enhance lips for a fuller appearance and restore volume and
fullness to the face by smoothing out facial wrinkles and folds.

How long does this last?

When Restylane is used for the first time, Dr. Hanna notes, studies show that average results can
last anywhere from 6 to 9 months. With a follow-up treatment, you can expect results to last up
to 18 months.

How often do I need to perform treatments?

To get results for up to 18 months, you likely will only need a follow-up treatment 4.5 or 9 months
after their initial treatment.

• On average, only half the amount of Restylane used at the initial treatment is needed at the
  follow-up treatment.
• Dr. Hanna suggests that more collagen is formed in most patients who repeatedly get dermal
  fillers over time—which means fewer injections are needed for upkeep and maintenance.

Am I eligible for Restylane?

Ultimately, your doctor or a technician will decide whether or not you're eligible for Restylane. But
Restylane is a low-risk option for treating wrinkles, and you'll typically be approved if you are:

• Over the age of 35
• Aren't allergic to hyaluronic acid

How much does Restylane cost?

The usual rate for a Restylane treatment is somewhere between £150 to £300 per session.

Are there any side effects?

First off, the treatment is not particularly painful. "One of the benefits of Restylane is that it contains
a local anesthetic for your comfort," explains Dr. Hanna, which means the process is potentially less
painful than other cosmetic fillers.

As for common side effects, you might experience temporary injection-site reactions, such as redness,
swelling, and bruising. A headache is also possible. The side effects normally last fewer than 7 days
in nasolabial folds and fewer than 14 days in lips.

How soon can I see results?

Restylane instantly adds volume when it's injected, so results are noticeable immediately after a
treatment. Final results can be seen 1–2 weeks after any potential swelling or bruising has
had time to subside.
