Restylane
Weight loss, pregnancy, and genetics are all factors that can cause the tummy to develop loose, sagging skin and a bulging appearance. Though exercise can provide limited toning benefits, no amount of exercise or dieting can restore firmness to loose skin or repair muscles that have been stretched and separated as a result of pregnancy.

The RHA Collection: Modern science at its best
The RHA Collection was developed to adapt to the movement of the face while treating lines and wrinkles. Using the highly effective active ingredient of hyaluronic acid (HA), the RHA Collection was designed to protect and preserve the HA’s natural structure with very few added chemicals.
This means that the hyaluronic acid in the RHA Collection mimics the natural hyaluronic acid found in your skin — which is great news, considering it’s the moisture-binding substance that keeps the skin plump, firm, and hydrated.
In the past, cosmetic injectables that target dynamic wrinkles paralyzed the muscles too much, resulting in a “frozen” appearance. The RHA Collection offers a much more natural-looking outcome.

What are dynamic wrinkles?
In this world, there are static wrinkles and there are dynamic wrinkles. Static wrinkles are the ones that are always there — whether an expression is being made or not.

Dynamic wrinkles are the ones that form when you laugh, frown, squint, furrow your forehead, and make other expressions.
It’s great to target dynamic wrinkles while they’re still dynamic, because it can prevent them from becoming static (permanent)
The 3 Levels of the RHA Collection
Each level of the RHA Collection has different “stretch” ability and strength to most effectively meet your specific aesthetic goals. The level chosen for you will be determined by the progression of your wrinkles. The three levels are RHA 2, RHA 3, and RHA 4.
Candidates for RHA fillers
- Must be at least 22 years old
- Are not pregnant, trying to become pregnant, or breastfeeding
- Are not allergic to RHA’s ingredients
- Should not have an infection or wound in the treatment area
Treatment details
Your skin may be numbed with a topical anesthetic to help you with the injections, but some patients don’t find this necessary. Treatment time takes approximately 20 minutes.
Recovery and results
Recovery time with the RHA is very minimal. After treatment, you will be given a cooling pack, and you may experience mild bruising and/or swelling for up to one week. Patients are excited to see results immediately following treatment, with final results visible in one week.
Although the RHA Collection will eventually be broken down by the body, as with all dermal fillers, it does provide longer-lasting results than most. The RHAs have been clinically proven to last up to 15 months, as its unique formula has been developed to last longer.
