Hyaluronic acid: the star ingredient for hydrated, plump and radiant skin

Hyaluronic acid has become a staple in the world of natural cosmetics and aesthetic medicine. Naturally present in the human body, this active ingredient acts like a sponge, capable of retaining up to 1,000 times its weight in water , thus contributing to deep hydration , firmness , and skin elasticity. Whether you have dry, oily, or combination skin, it adapts to each skin type to reduce wrinkles and fine lines, plump the skin tissue, and support the skin barrier.

At Nüssa , we have chosen an innovative form, 99% of natural origin, to offer your face an anti-aging solution that is effective, sensorial and respectful of your skin .

What is hyaluronic acid?

A molecule naturally present in the body

Hyaluronic acid is a molecule naturally produced by our bodies. It is found in several tissues: skin, joints, eyes, etc. In the dermis, it acts as a "matrix," retaining water and ensuring cellular cohesion. With age, its production decreases significantly, leading to a loss of volume and elasticity, and the appearance of the first wrinkles.

A fundamental role in skin hydration

A true “molecular sponge,” hyaluronic acid retains water in the tissues, thus maintaining optimal skin hydration. It strengthens the skin barrier and helps prevent dehydration caused by external aggressors (sun, pollution, cold, oxidative stress). It integrates perfectly into a natural skincare routine, whether as a face serum , cream, or mist.

The different molecular weights and their effects

Hyaluronic acid exists in several forms, depending on its molecular weight :

• High molecular weight : acts on the surface to form a protective film and prevent water loss.

• Low molecular weight : penetrates deeper to restart fibroblast activity and stimulate collagen and elastin production.

• Very low molecular weight : targets the deep layers of the dermis for intensive anti-aging effects.

Nüssa favours hyaluronic acid with optimal bioavailability, integrated into a spray serum formulated for all skin types.

What are the benefits of hyaluronic acid for the skin?

Deep hydration: retaining up to 1000 times your weight in water

The most well-known benefit of hyaluronic acid is its exceptional ability to retain water . A single molecule can capture up to 1,000 times its weight in water , thus restoring the skin's moisture reserves. This helps maintain optimal hydration levels and prevent dehydration , particularly in sensitive areas such as around the eyes and on the cheeks.

Well-hydrated skin is more supple, more resilient, and visibly more radiant. An essential ingredient to incorporate into your daily skincare routine , especially for dry or dehydrated skin.

Plumping and filling: wrinkles, fine lines and loss of volume

Hyaluronic acid acts as a natural filler . By adding volume to tissues, it smooths fine lines and reduces wrinkles , while restoring a plump appearance to the skin. Its effect is particularly visible on areas weakened by age : nasolabial folds, crow's feet, lip contour…

Thanks to its skin-supporting action, it is also used to counteract age-related volume loss . The result: smoother, plumper, younger-looking skin.

Firmness and elasticity: a natural lifting effect

By stimulating the production of collagen and elastin , hyaluronic acid strengthens the structure of the dermis and combats skin laxity. It contributes to firmer , more toned, and elastic skin, a true "lifting effect" without surgery.

When used regularly, especially via a hydrating serum, it becomes a true natural anti-aging ally , perfectly tolerated even by sensitive skin.

Soothing and repairing the skin barrier

In addition to its aesthetic effects, hyaluronic acid possesses restorative properties . It strengthens the skin barrier , reduces inflammation , and promotes the healing of minor injuries. It is therefore an excellent active ingredient for calming reactive skin prone to redness, or for complementing post-sun exposure skincare.

It also acts on microcirculation , soothing tightness and discomfort associated with dryness or irritation.

Radiant complexion: improved texture, refined skin texture

By improving hydration and skin tissue structure, hyaluronic acid also contributes to a more even and radiant complexion . It refines skin texture , minimizes the appearance of pores, and leaves a fresh and glowing look , as if after a good night's sleep.

The result: the face appears visibly younger, clearer, more alive.

Incorporate hyaluronic acid into your skincare routine

In the morning: hydration booster and protection

In the morning, hyaluronic acid acts as a true hydrating shield . Applied to clean skin, it helps retain water in the epidermis , preserve elasticity , and protect the skin barrier from external aggressors (pollution, wind, sun, etc.). An essential step to prepare the skin to receive subsequent treatments and enhance the complexion .

For a quick and effective application, opt for a face serum in mist form, such as the Nüssa plumping spray serum , which offers an immediate plumping and fresh effect.

In the evening: repair and anti-aging effect

In the evening, the skin enters a phase of cellular regeneration . This is the ideal time to promote skin tissue repair and reduce the signs of aging . Hyaluronic acid, combined with nourishing and soothing active ingredients, will plump the skin , smooth lines, and strengthen its supporting structure .

Pair it with rich, natural nighttime skincare to maximize the benefits.

Serum or cream: which to choose according to your skin type?

• For dehydrated or dry skin : combine a concentrated hyaluronic acid serum with a nourishing cream for deep and surface action.

• Sensitive skin : opt for a natural and minimalist formula, without preservatives or alcohol, to limit the risk of irritation.

Combining it with vitamin C or niacinamide: a winning duo?

Hyaluronic acid can be combined with other active ingredients for a comprehensive effect:

• Vitamin C : to boost radiance and strengthen antioxidant protection .

• Niacinamide : to soothe, regulate sebum and improve skin texture .

These combinations are particularly recommended in an anti-aging skincare routine and help to optimize results over the long term .
