Every woman (and man!) dreams of a radiant, youthful, and harmonious face. Aesthetic medicine was created to meet this legitimate desire. Among the most popular and natural solutions are hyaluronic acid injections (fillers and skinboosters). These treatments restore volume, smooth wrinkles, and restore radiance without surgery.
History of hyaluronic acid
Discovered in 1934 in the vitreous humor of ox eyes, hyaluronic acid (HA) quickly revealed its exceptional hydrating and filling properties. Today, the HA used in aesthetics is synthesized in a laboratory: it is a CE-marked medical device, rigorously controlled by the ANSM.
Since the 2000s, "fillers" (injectable hyaluronic acid-based fillers) have gained worldwide popularity thanks to their safety and reversibility.
Hyaluronic acid: what exactly is it?
Hyaluronic acid is a molecule naturally present in our body (skin, joints, eyes). It retains up to 1,000 times its weight in water and ensures tissue hydration and suppleness. With age, its production decreases by about 6% every 10 years, leading to volume loss, wrinkles, and skin laxity.
HA-based fillers are biodegradable: the body does not recognize them as foreign bodies and naturally reabsorbs them within 8 to 18 months depending on the area and skin type. They are strictly regulated: since July 2024, they can only be sold to doctors and dental surgeons with a medical prescription.
Why choose hyaluronic acid injections?
Skin aging, smoking, alcohol, pollution, sun exposure, and genetics accelerate dehydration and loss of dermal density. The result: nasolabial folds, marionette lines, sagging cheekbones, thinned lips, hollow dark circles...
Hyaluronic acid injections allow to:
- Restore lost volume
- Deeply hydrate the skin
- Smooth fine lines and wrinkles
- Redefine facial contours naturally
Major advantage: immediate results, quick procedure (15-30 min), without general anesthesia or scars, and much less expensive than a surgical facelift.
What are the indications for hyaluronic acid-based fillers?
The treated areas are very broad:
- Face: nasolabial folds, marionette lines, frown lines, crow's feet, cheekbones, chin, facial oval, lips
- Eyes: hollow dark circles and tear troughs
- Other areas: neck, décolleté, back of hands, plantar pads (for comfort with high heels)
Different types of fillers according to cross-linking
The texture of the hyaluronic acid gel (more or less cross-linked) determines its use:
- Fluid (low cross-linking): fine lines, perioral lines, crow's feet, delicate dark circles Examples: Hyamira Soft (15 mg), Infini S (20 mg), DIVES Ridules (16 mg)
- Medium density: nasolabial folds, marionette lines, slight nose correction, lip augmentation Examples: Hyamira Basic (20 mg), Infini M (21 mg), DIVES Universal (20 mg)
- Very dense (highly cross-linked): volumetric restoration (cheekbones, chin, facial oval, lips) Examples: Hyamira Forte (25 mg), Infini L/XL (24-26 mg), DIVES Volume (24 mg)
Skinboosters: revolutionary deep hydration
Skinboosters inject a very fluid hyaluronic acid in micro-injections (meso-lift or cannula technique) into the mid-dermis. They do not change volumes but boost hydration, firmness, and radiance.
Ideal indications from age 30 (prevention) or for mature skin. Areas: face, neck, décolleté, hands.
A prospective study published in 2025 (81 patients, 3 sessions) showed a significant and lasting improvement in hydration, firmness, and radiance for up to 6 months, with excellent tolerability.
Results, duration, and post-injection care
- Immediate effect, optimal at 10-15 days
- Duration: 8-12 months on average (up to 18 months on cheekbones/folds)
- Slight swelling or bruising possible for 2-3 days
Possible complications and contraindications
Even if fillers are very safe when performed by a doctor, adverse effects exist (swelling, hematomas, rarely necrosis or infection). The ANSM reminds that only doctors are authorized to perform these injections, precisely to limit serious risks (infections, necrosis, blindness).
Contraindications: pregnancy, breastfeeding, active autoimmune diseases, ongoing infection, known allergy.
A recent European surveillance (2026) tested 17 products: 13 were compliant, confirming the need to choose qualified practitioners and traceable products.
After your session: essential instructions
- Avoid makeup, exercise, and dental care for 24 hours
- No sun, sauna, or hammam for 2 weeks
- No vigorous massage for 48 hours
- Avoid anti-inflammatories for the first 4 hours
Home care to prolong the effects
To maximize and maintain results:
- Creams and serums with hyaluronic acid, argireline (botox-like effect), DMAE (firming effect)
- Gentle mandelic peel
- Food supplements: drinkable marine collagen + anti-aging complexes
Conclusion: a safe treatment... in the hands of a professional
Hyaluronic acid injections today offer one of the best benefit/risk ratios in aesthetic medicine. For natural and safe results, always choose a qualified aesthetic doctor.
