The Hyalu B5 range

Hyalu B5 products are designed for skin that is not necessarily dry but dehydrated. Whilst dry skin occurs due to lack of oil, dehydrated skin occurs when there is not enough moisture in the skin. Dehydrated skin is a condition rather than a skin type, and it is characterised by low moisture volume and poor skin elasticity. Hyaluronic acid is a brilliant ingredient for treating dehydrated skin because it works to attract and retain moisture in order to improve skin volume and texture.

Enriched with two pure hyaluronic acids of differing molecule sizes, Hyalu B5 products are designed to boost skin hydration at both surface and deep levels. Hyalu B5 products also contain active ingredient Vitamin B5 to aid skin reparation and madecassoside to stimulate collagen synthesis and improve skin elasticity. Not only is this plumping effect helpful for those with dehydrated skin, but it is also excellent for mature skin and combatting the common signs of ageing such as fine lines, wrinkles and dullness.

Unlike other treatments for dehydrated skin, Hyalu B5 products have been specially formulated with sensitive skin in mind and have minimal formulations to reduce the risk of irritation. Like all La Roche-Posay products, the Hyalu B5 range has undergone rigorous dermatological testing to ensure it is safe and effective for those with skin prone to sensitivity.

Hyalu B5 Hyaluronic Acid Serum

Hyalu B5 Hyaluronic Acid Serum

The Hyalu B5 Hyaluronic Acid Serum delivers a potent dose of hyaluronic acid to instantly improve skin suppleness, bounce and radiance. Within four hours of application, the skin feels more hydrated and elasticity and firmness are visibly improved. After a month of daily use, 71% of consumers agreed that wrinkles appeared reduced and 87% reported that skin seemed more supple and even.

The Hyalu B5 Hyaluronic Acid Serum should be applied at night after cleansing in order to hydrate and repair the skin during sleep. It should be followed by a nourishing moisturiser.

Hyalu B5 Hyaluronic Acid Cream

Hyalu B5 Hyaluronic Acid Cream

Hyalu B5 Hyaluronic Acid Cream is a deeply hydrating moisturiser for skin that is showing signs of ageing. It is designed to lock in hydration to leave the skin looking plump and feeling fresh, gradually reduce the depth of fine lines and wrinkles, and help the complexion to become more even. It has a relatively lightweight texture which makes it ideal for those with normal to combination dehydrated or ageing skin.

This product should be used as a daily moisturiser in the mornings after cleansing and toning, followed with a broad-spectrum UVA/UVB protection sunscreen. It could also be used as an evening moisturiser, particularly alongside the Hyalu B5 Serum to maximise hydration overnight.

Hyalu B5 Eyes

Hyalu B5 Eyes

A deeply hydrating eye cream, Hyalu B5 Eyes contains a high concentration of Vitamin B5 to support skin’s natural renewal process in the delicate eye contour. It is ideal for those who have deep wrinkles around the eyes, providing an instantly refreshing feeling and gradually reducing the severity of lines to give a more awakened appearance.

Hyalu B5 Eyes should be used morning and night around the eye contour, applied from the inner corner of the eye outwards. After twice-daily use, fine lines look reduced and the eye contour feels restored and refreshed.

Hyalu B5 Riche Cream

Hyalu B5 Riche Cream

Hyalu B5 Riche Cream is a hydrating daily moisturiser designed for people with dehydrated or ageing skin that is also very dry. It contains shea butter to support the skin's lipidic barrier and alleviate the itchiness and flakiness that is common with dry skin. It has a rich, luxurious texture that instantly soothes and smooths the skin, leaving it feeling more supple and comfortable.

For the best results, use Hyalu B5 Riche Cream in the morning and at night after cleansing and following the Hyalu B5 Hyaluronic Acid Serum.

Hyalu B5 Aquagel SPF30

Hyalu B5 Aquagel SPF30

Hyalu B5 Aquagel SPF30 is a lightweight, fast-absorbing gel which delivers instant hydration and provides broad spectrum UV protection. Antioxidants stimulate the skin’s natural repairing process and improve skin texture. As well as being hypoallergenic, this product is also non-comedogenic, meaning it won't contribute to blocked pores and subsequent blackheads and pimples.

Hyalu B5 Aquagel SPF30 should be applied to the face and neck in the morning after cleansing and serums, 30 minutes before sun exposure. It is massaged easily into the skin without leaving any stickiness behind.

Frequently asked questions

What is the difference between dry skin and dehydrated skin?

Dry skin is a skin type. People with dry skin produce less sebum than those with normal skin, and sebum is essential for retaining moisture and protecting the skin against external aggressors. Dry skin tends to be itchy and flaky.

Dehydrated skin is a condition. Skin becomes dehydrated due to a lack of water, often as a result of external stressors such as extreme weather, exposure to pollutants, poor diet and high caffeine consumption. Dehydrated skin tends to be dull, inflamed or congested, with wrinkles and lines being more pronounced.

What skincare ingredients should I avoid if I have dehydrated skin?

If you have dehydrated skin you should avoid ingredients with drying or astringent effects, such as alcohol, salicylic acid and glycolic acid.

How does hyaluronic acid benefit the skin?

Hyaluronic acid helps the skin to retain moisture. Hyaluronic acid penetrates different layers of the skin depending on its molecular size. The most effective products, such as those in the Hyalu B5 range from La Roche-Posay, contain large hyaluronic acid molecules to hydrate the surface of the skin and reduce the appearance of fine lines and wrinkles, as well as smaller molecules to penetrate more deeply into the skin to improve volume.
