Hyaluronic acid Paris

Over time, the skin becomes dehydrated, and collagen and elastin fibres shrink and lose their structure. All this leads to a loss of skin volume. This is when facial wrinkles and folds form. Facial ageing is also caused by other agents, such as hormonal changes during menopause, UV radiation from the sun and, of course, tobacco.

Presentation

Hyaluronic acid (HA) injections are an effective solution to compensate for facial ageing. In addition, hyaluronic acid has been used for over 25 years both in aesthetic medicine and in many medical fields such as rheumatology, ophthalmology, ENT and gynaecology. They help erase wrinkles and, unlike botulinum toxin injections, they do not affect the mobility of facial muscles, so facial expressions are not altered. Hyaluronic acid is a polysaccharide, i.e., a molecule formed by thousands of sugar particles, which are naturally present in living organisms. These molecules attract and retain water, resulting in excellent hydration capacity. This hydration improves the elasticity of the skin and face, neck, décolleté and hands. Hyaluronic acid is biodegradable and absorbable between 12–18 months, depending on a person's metabolism.

Indications

Hyaluronic acid injections are used to treat "lion's" or glabella lines, hollow dark circles, nasolabial folds, perioral lines and marionette lines.

They help restore the volume of the cheekbones, temples and cheeks. They also treat saggy jowls.

Lip volume can be increased, and their borders redefined.

The injections can also reduce the appearance of skin depressions caused by acne scars or wounds.

Other treatments include creating volume in the chin, forehead, temples, or treating certain nasal defects and facial anomalies.
However, there are some very specific contraindications to note such as pregnancy, breastfeeding, autoimmune diseases or bleeding disorders.

Operating procedure

Most hyaluronic acids contain a local anaesthetic, so the injection is painless. The procedure can be performed over a period of 20–30 minutes. These injections can also be a complementary treatment to a blepharoplasty, a facelift or a laser resurfacing, or dermabrasion. Finally, hyaluronic acid can be combined with botulinum toxin injections.

Post treatment

Some minor redness may appear after the injections. A slight swelling can sometimes occur as well as small bruises, which can be easily hidden under makeup. Some precautions must be taken on the day of the injection, such as avoiding any extreme exertion, taking aspirin, anti-inflammatory drugs and avoiding exposure to extreme heat such as the sun, sauna or hammam.

The result is immediate, natural, visible, and optimal after a week.

It should also be noted that, in the event of over-correction or in certain complications such as persistent swelling or an inflammatory reaction, the action of hyaluronic acid is reversible with an injection of hyaluronidase. This procedure leaves no scar and only one session is enough to correct a specific area, so the patient can continue their activities or work immediately after. Likewise, applying makeup immediately afterwards is perfectly possible. Sport can be resumed on the following day.
