What is it?

This skin tightening technique was popularized in Eastern Asia and South America. This technique uses a very watery liquid containing calcium hydroxylapatite microspheres placed beneath the superficial layer of skin to grow large amounts of collagen. The loose skin and wrinkles begin to subside after a series of 3 treatments. This product is a biostimulant, meaning your own body is responsible for producing the end result, unlike with fillers, neurotoxins, or threads.

What is the science behind this treatment?

This is an FDA-approved biocompatible, biodegradable, and resorbable biostimulatory substance consisting of calcium microspheres. It is a unique product that provides collagen biostimulation. After approximately 9–12 months, the calcium hydroxylapatite particles are degraded into calcium and phosphate which are eliminated through the urine. Although the product is excreted, the effect lasts at least 18 months or longer.

Who is a good candidate?

There are several types of candidates for this treatment:

1. The ideal patient is age 45 or older with thin skin, and moderate to severely loose skin. Ideal treatment areas include neck, chest, abdomen, buttocks, arms, elbows, and the knees.

2. The ideal patient has defined cellulite dimples that are visible when standing but tend to disappear when laying down or sitting.

3. The ideal patient is a healthy body weight but desires plumping of the buttock area or filling of hip dips. This procedure is referred to as a “non surgical buttock augmentation” or “non surgical BBL”.

The ideal candidate has loose or crepey skin.

How does the process work?

First the body area is numbed using injectable lidocaine so you don’t feel anything. Next using a cannula, calcium hydroxyapatite is placed followed by new tissue formation through neocollagenesis, elastin production, angiogenesis, hyaluronic acid production, and dermal cell proliferation. The result is a long-lasting aesthetic improvement for ≥18 months with tight and elastic skin and increased skin thickness.

What areas can be treated?

Ideal treatment areas include lower face, neck, chest, abdomen, arms, elbows, and the knees. We can also inject cellulite dimples or use this product to simply shape, enhance, or tone the buttocks or thighs.

How long does it last?

Regarding effect duration, it may depend on many factors, such as the patient’s age and metabolism, and the relative dynamic motion of the area in which the substance is placed. Published data show calcium hydroxyapatite treatment results lasting up to 18–24 months.

What are the side effects?

Based on an clinical studies, the calcium hydroxylapatite product has a good safety profile. Swelling is the most common reaction. Bruises are possible. Nodules are a rare but possible side effect. If nodules develop, they can be treated in our clinic.

What is the downtime?

Exposure of the treated area to excessive heat should be minimized for approximately 24 hours. Direct sun and sunbathing should be avoided for 7 days. A cold pack can be used to minimize tenderness, swelling, and bruising. Patients should plan for 2 days of mild swelling. Bruises may take 2 weeks to metabolize. Body parts farther away from the heart may bruise longer than 2 weeks.

How much does it cost?

This treatment starts at $800 and up per session. Larger areas may cost more. Call us at 615-873-4110 to book a complimentary consultation.
