The Benefits

Nourishing

Nourishing skincare focuses on providing a deeply comforting, soothing, and softening experience with richer product formats. Ingredients like oils and ceramides nourish your skin barrier, replenishing essential lipids and hydration to boost resilience and suppleness. These formulas leave your skin feeling nurtured and instantly improve rough texture. Well-nourished skin is less prone to dryness, dehydration, and sensitivity, giving you a more radiant and healthy appearance.

Hydrating

Hydration is all about the water content in your skin that keeps it supple and healthy. Humectants, ingredients with water-binding properties, deliver this hydration by attracting water molecules from the atmosphere. For the best results, apply hydrating serums right after a shower. Humectants not only replenish your skin's hydration but also enhance its water retention, creating a long-lasting hydration reservoir. Adding humectants like hyaluronic acid to your routine will restore your skin's healthy glow, minimize fine lines, and provide a plumping effect.

Brightening (Oxygenation)

Brightening your skin means restoring its natural glow. One way to do this is through oxygenation, which helps skin cells "breathe" better by delivering more oxygen. Perfluorocarbons are key ingredients that carry oxygen into the skin cells. This process also boosts blood circulation and removes skin cell waste, resulting in brighter, more radiant skin.

Plumping

Skin plumping involves using active ingredients to boost the production of key structural components like collagen, the dermal-epidermal junction, and glycosaminoglycans (GAGs), giving your skin more volume and density. Collagen provides structural support and firmness, while the dermal-epidermal junction, a thin connective layer, ensures smooth, wrinkle-free skin by facilitating cell communication. GAGs, like hyaluronic acid, keep your skin hydrated and plump from within. By stimulating these components, active ingredients help restore your skin's plumpness and radiance.

Anti-Wrinkle

Anti-wrinkle products work to smooth out fine lines and wrinkles by boosting collagen and elastin, essential proteins that keep your skin glowing. Collagen helps reduce wrinkle depth, while elastin shortens their length. Keeping your skin hydrated is crucial, as dehydration can make wrinkles more noticeable. For smooth, bouncy skin, ensure you stay well-hydrated and use products that promote collagen and elastin production.

Firming

Skin firming focuses on boosting your skin's elasticity and tightness to reduce sagging and wrinkles, leaving your skin looking firmer. This is done by stimulating fibroblasts to produce more elastin, the protein that helps your skin stretch and bounce back. To keep your skin firm longer, antioxidants protect these elastin fibres from free radical damage, which can cause early breakdown. This combined action helps maintain a youthful, resilient complexion.

Lifting

Lifting is all about visibly firming and tightening skin that shows signs of sagging. As we age, our skin produces less collagen and elastin, the proteins that keep it firm and elastic. Sun exposure and pollution make this worse, leading to a sagging appearance. Lifting products work by creating a tightening film on your skin for an immediate lift, while also rejuvenating it over time. These actives stimulate collagen production and improve skin tone and elasticity, helping to restore facial contours and enhance overall firmness.

Repairing

Repairing your skin means restoring cells damaged by external factors like UV rays and free radicals, which can harm cell DNA and slow regeneration. Although our cells naturally repair themselves, this ability weakens over time due to ageing and repeated environmental exposure. Active ingredients can boost this natural process, preserving your skin's health, elasticity, and radiance. By supporting skin cell repair, these ingredients combat premature ageing and help maintain a firm, plump, and toned complexion.

Antioxidant

Antioxidant Protection shields your skin and preserves its youthful glow. It refers to a defence system that protects against harmful molecules and keeps your complexion healthy and radiant. Free radicals, those incredibly reactive molecules, come from everyday sources like sunlight, diet, smoking, and pollution. They attack healthy cells, accelerating skin ageing, causing wrinkles, loss of firmness, pigmentation, and dullness.

Incorporating antioxidants, such as vitamins C and E, into your skincare routine creates a protective shield on your skin. These powerful ingredients neutralise free radicals, preventing them from causing damage. The result is skin that stays youthful, firm, and luminous.

Active Ingredients

Low Molecular Weight Hyaluronic Acid

Low Molecular Weight Hyaluronic Acid or Sodium Hyaluronate, is a salt form of naturally occurring hyaluronic acid. Sodium Hyaluronate has a low molecular size (<70 kDa), which allows it to penetrate the skin deeper and more effectively. Sodium Hyaluronate has superior hydrating and skin-plumping benefits. Increased skin hydration also contributes to efficient natural skin exfoliation, supporting the skin's natural renewal cycle.

Low Molecular Weight Hyaluronic Acid (Sodium Hyaluronate)

Low Molecular Weight Hyaluronic Acid or Sodium Hyaluronate, is a salt form of naturally occurring hyaluronic acid. Sodium Hyaluronate has a low molecular size (<70 kDa), which allows it to penetrate the skin deeper and more effectively. Sodium Hyaluronate has superior hydrating and skin-plumping benefits. Increased skin hydration also contributes to efficient natural skin exfoliation, supporting the skin's natural renewal cycle.

Trio of Polysaccharides

The trio of Polysaccharides, a string of glucose molecules, include high molecular weight Hyaluronic Acid, Alginate, and Pullulan. Together, they create a breathable film on the skin, enhancing the barrier function and boosting water retention for deeply hydrated skin.

Biologique Recherche Oxygenating Complex

Biologique Recherche's "Oxygenating Complex" utilises Perfluorodecalin to enhance cellular respiration by delivering oxygen deep into the skin. This ingredient effectively carries oxygen to the skin's deepest layers, promoting wound healing, rejuvenation, plumping, reducing wrinkles, and brightening the complexion.

Walnut Extract

Walnut Extract counteracts skin ageing by stimulating fibroblast activity and inhibiting elastase. Meaning that it prevents the natural elastin in our skin from degrading, promoting a more elastic and smoother skin, whilst reducing fine lines & wrinkles and promoting a more toned skin. This ingredient also has powerful antioxidant properties which prevents cells from oxidative stress.

Chaperone Proteins

Chaperone Proteins, produced by microorganisms from the Valaus Glacier, have adapted to survive in extremely harsh conditions. In skincare, they support Elastin & Collagen activity, offering firming and plumping benefits. Additionally, they boost cellular energy, resulting in a brighter complexion.

High Moleclular Weight Hyaluronic Acid (Hyaluronic Acid)

High Moleclular Weight Hyaluronic Acid has a larger molecular size (>1000kDA), which tends to sit on the top layer of the skin, providing surface hydration and improving water retention. It acts as a potent humectant, drawing hydration from the environment into the skin, which helps to plump and smooth the skin's surface texture. Its larger size limits its ability to penetrate deeply into the skin compared to lower molecular weight Hyalurons, making it ideal for providing surface-enhancing hydration provided from other forms of hyalurons and maintaining skin suppleness.

Red Seaweed & Tara Fruit Extract Complex

Red Seaweed & Tara Fruit Extract Complex supercharges the skin's hydration reservoirs and improves its water retention capabilities. It also has a strong lifting effect helping to tighten facial contours and reduce the appearance of fine lines and wrinkles.
