Hyaluronic acid and hydration: innovations for radiant skin

Recent formulations aim not only to maximise the skin's moisture retention capacity, but also to improve the durability of results and minimise side effects, such as redness or irritation.
Whether it's multi-molecular weight serums, time-release fillers or synergistic combinations of active ingredients, the latest products offer deeper, longer-lasting hydration that's better adapted to the specific needs of each skin type. These new approaches are revolutionising the world of moisturising care, for radiant, revitalised skin.

Multi-molecular weight formulations: tailor-made hydration  

Multi-molecular weight hyaluronic acid products are gaining in popularity. These formulations contain hyaluronic acid molecules of different molecular weights to provide multi-dimensional hydration, tailored to the needs of each skin type.
High molecular weight molecules moisturise the surface layer of the skin.
Medium molecular weight molecules moisturise the skin's intermediate layer.
Low molecular weight molecules moisturise the deep layer of the skin.

Encapsulated hyaluronic acid 

In 2024, encapsulated hyaluronic acid formulations are gaining ground for their ability to prolong moisturising effects and improve absorption of the product into the skin. This technique involves encapsulating hyaluronic acid molecules in lipidic or polymeric structures that are gradually released into the skin.
Encapsulation not only protects the hyaluronic acid from being broken down by the skin's enzymes, but also allows it to deliver its moisturising benefits in a controlled way over an extended period. This means that hydration is maintained for longer, reducing the need to reapply the product.
These products offer hydration that lasts all day, even under conditions of environmental stress or dryness.

Sustained-release hyaluronic acid fillers  

In aesthetic medicine sustained-release hyaluronic acid fillers are a major innovation. These fillers are formulated to release hyaluronic acid gradually into the skin over a longer period, ensuring continuous hydration and a lasting improvement in skin quality.
These new formulations prolong the beneficial effects of hyaluronic acid, reducing the frequency of injection sessions. Products such as Restylane Refyne and the Juvederm Volite are designed to maintain deep hydration while improving the skin's elasticity and luminosity.
These fillers are particularly suitable for patients looking to prevent the signs of ageing or improve the quality of their skin once a year. They are used to intensely moisturise specific areas such as the face and neck. cheeksthe temples and lip contour, the plumping effect is natural.

Cross-linked and slightly cross-linked hyaluronic acid 

Hyaluronic acid can be cross-linked or weakly cross-linked depending on the structure of its molecules.

• Cross-linked hyaluronic acid is denser and thicker, designed for injections to fill deep wrinkles or restore facial volumes. Fillers such as Juvederm Voluma or the Restylane Lyft use this formulation to provide long-lasting structural support while hydrating the skin from the inside out.
• Low cross-linked hyaluronic acid is more fluid and is used for superficial injections. The Skinboosters are widely used to improve skin texture and provide deep hydration without altering the contours of the face.

This distinction allows doctors to choose the formulation best suited to the specific needs of each patient, guaranteeing optimal results in terms of hydration and natural restructuring of the face.

Combination of hyaluronic acid with other active ingredients for enhanced hydration 

Hyaluronic acid is often combined with other active ingredients to maximise its moisturising effects and offer additional benefits.

• Hyaluronic acid and peptides Peptides: Peptides help stimulate collagen production, boosting the skin's firmness and elasticity. One example is Olay Regenerist Micro-Sculpting Cream which combines hyaluronic acid and peptides to hydrate and plump the skin.
• Hyaluronic acid and vitamin C This combination is perfect for moisturising the skin, protecting it from damage caused by free radicals and brightening the complexion.
• Hyaluronic acid and niacinamide Niacinamide: niacinamide is renowned for its anti-inflammatory and soothing properties, ideal for sensitive or acne-prone skin. This combination is used to improve hydration while calming redness.

These combined formulations respond to growing consumer demand for multi-functional products that simplify skincare routines while delivering maximum results.
