Hyaluronic acid injection has been one of the leading products in the field of aesthetic medicine in the last 20 years, with almost 2 million injections per year in the USA. This filler helps to correct static wrinkles in the lower third of the face, creating a rejuvenated and refreshed face.
The causes: how do wrinkles occur ?
The skin is organized in two anatomical layers: the epidermis is a superficial, non-vascular component that rests on the dermis. The second underlying vascularized layer nourishes and protects the epidermis.
A wrinkle is characterized as a persistent skin fold that can be shaped in two distinct ways:
- The skin can wrinkle as a result of hypercontraction of the muscles of the skin: these are dynamic wrinkles or lines of expression;
- The skin can wrinkle because the dermis loses its volume with age, so that the epidermis "falls" into the fold: these are called static wrinkles or aging wrinkles.
Static wrinkles develop particularly in the lower part of your face from the age of 40.
The wrinkles of the upper lip are the vertical wrinkles named wrinkles of the sun, smoker's wrinkles or "barcodes" wrinkles: they give an appearance of pout.
Puppet wrinkles or bitterness folds stretch between the corner of the lips and the chin. They're producing a negative impression of pout or disgust.
Nasolabial wrinkles or nasolabial folds stretch the valley of tears between the nose and mouth, affecting the entire lower part of the face with a serious or weary look.
These static wrinkles are all indicated by injections of hyaluronic acid.
Concept: How does hyaluronic acid help remove wrinkles?
Hyaluronic acid is a normal macromolecule present in all connective tissues where it occurs as an elastic and versatile gel in which fibers and cells are bathed.
This dermal hyaluronic acid (HA) offers the skin its softness, volume and hydration. HA is often compared to a sponge that catches water molecules.
Injectable hyaluronic acid can serve as a volumizing filler, with a more or less noticeable effect depending on the molecular weight of this HA.
By restoring the thickness of the dermis, the HA injection lifts the epidermal tissue so that the epidermis tightens: the wrinkle or furrow is filled in. In addition, HA absorbs water and rehydrates the skin, improving its vitality and metabolism.
Some dynamic wrinkles, such as forehead wrinkles, can also be decreased with an injection of hyaluronic acid, although the treatment of choice remains a Botox (botulinum toxin) injection. The hyaluronic acid, which has little volume, will give to a hollowed-out bottom a little volume, which structurally tightens the skin and smoothes out forehead wrinkles.
Depending on the situation, your aesthetic doctor in Dubai will be able to select either a large-volume injection (1 ml syringe) administered at 1 or more stages, or a multitude of small injections for smoothing and rejuvenating the skin, such as mesotherapy or Skinbooster. In this case, the practitioner favors a low molecular weight HA which is not cross-linked. The moisturizing effect helps to tighten the tissues and has a "medical lifting" effect.
Indications: which wrinkles can be treated by hyaluronic acid injection?
The injection of resorbable hyaluronic acid is used to remove all static wrinkles by filling and volumizing and even to reduce some dynamic wrinkles.
The doctor chooses the most suitable treatment for each patient each time to encourage a natural outcome:
- Injection of hyaluronic acid on a unique point, such as the filling of wrinkles in the naso-labial fold;
- Hyaluronic acid injections at a variety of targeted locations, to smooth the skin by restoring volume (oval of the face) or to fill multiple static wrinkles with a harmonious appearance of the area;
- Hyaluronic acid injection, to have a smoothing effect without a visible volumizing effect.
These anti-wrinkle injections are usually painless, and the local anesthetic form of lidocaine is mixed with hyaluronic acid in the syringe.
What are the results of the hyaluronic acid injection on the wrinkles?
If the result is visible immediately after your session, it will be optimal after 10 to 15 days, once the oedema has been resorbed.
This facial rejuvenation effect is evident after 8 to 18 months, as the hyaluronic acid is slowly and naturally absorbed.
The before/after of an injection of hyaluronic acid is often impressive.
Static wrinkles fade away with filler, the skin is rehydrated and the tissues tighten for a smooth and bright complexion.
Hyaluronic acid treatment of static wrinkles on the lower face turns negative expressions of tiredness, disgust, seriousness or disappointment into positive emotions, with a younger, fresher and more pleasing face.
