Principle of hyaluronic acid

Hyaluronic acid is a substance naturally present in the body and therefore very well accepted and tolerated when it is injected (synthetic hyaluronic acid). It induces volume and improves the hydration and elasticity of the injected area.

Difference with Botox ® ?

Botox, by decreasing the muscle contraction signal, corrects the state of muscle hypercontraction responsible for wrinkles. The effect takes between 5 and 10 days to take effect.
Hyaluronic acid is a filler and thus allows the creation or restoration of volume. The effect is immediate.

There are different indications for hyaluronic acid.

  • Creation of projection to harmonize: lips, cheekbones, chin, jawline, buttocks, nose
  • Restoration of lost volumes: temples, forehead, dark circles, superficial wrinkles around the mouth and neck, “liquid” lifting, nasolabial folds
  • Genital area: restoration of labia majora volumes, vaginal hydration, G-spot injection for sexual pleasure, penis to increase volume

It can be injected in variable areas as shown above. There is a whole range of hyaluronic acid, with different and specific density, hold and properties. For each area and each indication, there is a specific and adapted hyaluronic acid.

Dr. Lucas uses the brand Stylage® mainly, which is one of the reference brands worldwide, but for dark circles, in certain patients at risk of Tyndall effect, he uses Teosyal Redensity II ® and for rhinoplasty with hyaluronic acid, he uses Restylane Lift®.

Warning :

Only doctors, with a license and an insurance, can inject hyaluronic acid in Switzerland. Laboratories selling hyaluronic acid are only authorized to sell it to doctors with a license. There are many counterfeits that can endanger your body, some of which cannot be corrected by Hyaluronidasis. In addition, an intra-vascular injection (into a vessel) can have dramatic consequences: necrosis, blindness.

Technique :

Topical anesthesia with cream or local anesthesia with Xylocaine on the entry point and filling with the cannula. The cannula is very often used by Dr. Lucas, because with its smooth, non-sharp tip, allows for a less painful injection with less hematoma.

Results :

Time to results: immediate
Longevity of results : 3 to 24 months depending on the product and on the patients (great variability). We note a greater resorption of hyaluronic acid in smokers.

Before the injection:

Inform Dr. Lucas of any anticoagulant medication (Sintrom, Coumadin, Eliquis, etc..) or Aspirin, special attention will be paid during the injections to avoid small vessels and prevent hematomas and for certain injections, a relay will be organized if medically possible
