Hyaluronic acid in the human body
Hyaluronic acid is a molecule naturally present in our body. This substance is naturally produced by the human body. It is mainly found in skin, joints, connective tissues and eyes. It is a glycosaminoglycan, a complex sugar capable of retaining up to 1 000 times its weight in water. This hydrating power makes it fundamental to skin suppleness, tissue elasticity, oxidative stress protection and cell regeneration.
Hyaluronic acid and skin ageing
With age, natural hyaluronic acid production gradually declines : concentration starts falling from 25 and may have decreased by over 50 % around 50.
This loss causes drier, less elastic skin, wrinkles and fine lines, progressive laxity and reduced volume in certain facial areas (cheekbones, temples, lips).
Skin ageing is therefore closely associated with reduced hyaluronic acid levels in both quantity and quality.
Hyaluronic acid in aesthetic medicine
Hyaluronic acid used in aesthetic medicine is a gel synthesised in laboratories through bacterial fermentation, then purified and sterilised. It is identical to what the body naturally produces, ensuring excellent tolerance and very few allergic reactions.
Applications are multiple : wrinkle filling (nasolabial folds, marionette lines), volume restoration (cheekbones, temples, chin, jawline), lip plumping, deep skin hydration (Skinboosters), hollow dark circle correction and improved skin quality (radiance, tone).
Injected at different depths (from superficial dermis to hypodermis), it provides tailored treatment adapted to each face’s needs.
What is the difference between hyaluronic acid and botulinum toxin ?
It is essential not to confuse hyaluronic acid and botulinum toxin, as they act differently.
Hyaluronic acid is a filler : it restores volume, corrects hollows, improves skin quality and may lift certain areas according to technique.
Botulinum toxin acts on muscular contraction to relax expression lines, particularly on the forehead, glabella and crow’s feet.
These treatments are often combined for harmonious, comprehensive results, but their mechanisms are entirely different and complementary.
Hyaluronic acid : is it a lasting treatment ?
Hyaluronic acid is absorbable : the body naturally breaks it down over time.
Depending on injected area, cross-linking (density) and individual metabolism, duration varies between 10 and 15 months.
Gradual absorption allows results to be adjusted over time without ever freezing the face. It offers ideal adaptability to respect natural facial evolution.
Hyaluronic acid : summary
Hyaluronic acid is naturally present in the body, recognised for exceptional hydration and its essential role in maintaining skin quality, suppleness and elasticity. Very well tolerated, it is now one of the most used aesthetic medical products, particularly for its absorbability, adjustability and versatility.
Whether filling a wrinkle, restoring volume or improving skin quality, hyaluronic acid offers a customisable, natural and gradual approach.
Hyaluronic acid is much more than a simple anti-ageing product. It is now a pillar of aesthetic medicine, supporting skin ageing gradually, naturally and with respect for facial features.
