Hyaluronic acid (HA) is one of the most researched active ingredients used in facial cosmetics. Known for its moisturizing and regenerative properties, it plays a crucial role in the daily care of mature, dehydrated, and aesthetically treated skin. In this article, we analyze how hyaluronic acid works on the face, why it should be included in professional facial cosmetics, and which Rue de Skin products contain effective forms of it.
Hyaluronic acid, naturally occurring in the skin, is responsible for binding water molecules and retaining them in the intercellular spaces. Its amount decreases significantly with age – after the age of 25, hyaluronic acid synthesis declines, which translates into loss of firmness, dehydration, and the appearance of wrinkles. Hence the need to supplement its levels in daily skincare. Hyaluronic acid for the face works not only on the surface of the epidermis but – depending on its molecular weight – can also penetrate deeper layers of the skin, improving its elasticity, smoothness, and flexibility.
Clinical studies show that regular use of cosmetics containing hyaluronic acid improves skin hydration, smooths wrinkles, and increases its resistance to external factors (Papakonstantinou et al., 2023; Brown and Jones, 2021). In the context of professional facial skin care, hyaluronic acid becomes not only a moisturizer but also a biologically active ingredient, supporting regeneration and hydrolipid balance.

A facial serum with hyaluronic acid is one of the most effective forms of skincare – thanks to its lightweight formula and high concentration of active ingredients, it absorbs quickly, doesn't weigh down the skin, and works in layers. A good hyaluronic acid serum should contain forms with different molecular weights – low-molecular-weight hyaluronic acid works deeply, while high-molecular-weight hyaluronic acid protects the skin's surface from dehydration.
This type of action is demonstrated by Our the best vitamin C serum – a formula combining the antioxidant properties of vitamin C, the protective properties of vitamin E, and the strengthening properties of ferulic acid with the presence of hyaluronic acid. This not only protects the skin against free radicals but also deeply moisturizes and prepares it for environmental exposure – even in the context of inter-treatment care.

A hyaluronic acid cream is a fundamental part of a daily skincare routine – for both women and men. Depending on the skin's needs, hyaluronic acid creams can moisturize, rebuild, or firm. It's important that they also contain substances that support HA's effects, such as ceramides, peptides, or niacinamide. This means that hyaluronic acid not only moisturizes but also "locks" moisture into the skin and supports its structure.
Our company has such a comprehensive formula regenerating face cream – a cream designed for daily care of mature and sensitive skin. NG ceramides, peptides, and niacinamide strengthen the epidermal barrier, while hyaluronic acid provides intense and long-lasting hydration.

Hyaluronic acid serum is a product that acts as a precise tool in the care of dehydrated, tired, and lacking elasticity skin. Regular use of hyaluronic acid serums brings tangible results – confirmed not only in office practice but also in clinical studies. A study by Brown and Jones (2021) demonstrated that after eight weeks of hyaluronic acid use, skin hydration, wrinkle visibility, and overall skin tone improved. Hyaluronic acid's effects are particularly important in conditions of a weakened epidermal barrier – for example, after aesthetic medicine treatments, where the skin requires gentle yet effective regeneration support.
It's a good idea to use a hyaluronic acid serum in your daily routine both morning and evening – either under your cream or as a standalone moisturizing step. Products containing hyaluronic acid should be applied to damp skin, which further increases the ingredient's water-binding capacity and enhances its smoothing effect.
The skin under the eyes is thin, devoid of sebaceous glands, and particularly susceptible to moisture loss. In this area, eye creams with hyaluronic acid act as a microshield – protecting, moisturizing, and improving elasticity. Low-molecular-weight hyaluronic acid penetrates the deeper layers of the epidermis, and its effects can be supported by caffeine, peptides, and antioxidants. Gentle but regular care of the eye area effectively reduces dehydration lines, improves skin smoothness, and eliminates signs of fatigue. Premium facial cosmetics often contain specially formulated versions of HA that do not cause irritation and are also suitable for sensitive and allergy-prone skin.
The combined action of hyaluronic acid and niacinamide is one of the most harmonious combinations in skincare. Niacinamide strengthens the lipid barrier, reduces discoloration, and has anti-inflammatory properties, while hyaluronic acid delivers water and maintains its level in the epidermis. This synergy works both preventatively and therapeutically, preventing dehydration and supporting skin in need of regeneration.
This formula can be found in niacinamide serum 10% – a lightweight yet multifunctional cosmetic designed for skincare between treatments. It works at both the epidermal barrier and deeper layers of the skin, providing hydration, evening out skin tone, and reducing reactivity.
