The Benefits

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.

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.

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.

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.

Brightening

Brightening your skin means restoring its natural glow. One of the best ways to do this is through exfoliation. By exfoliating, you promote faster skin cell turnover, replacing old, damaged cells with fresh, radiant ones. This keeps your skin looking vibrant and healthy.

Anti-Pigmentation

Dealing with pigmentation means targeting melanin overproduction to reduce dark spots and prevent new ones. Melanin production can be triggered by UV exposure, pollution, hormonal changes (like during pregnancy), and inflammation (from acne or cuts). This excess pigment is then transferred to surrounding cells in epidermis called keratinocytes, which then moves to the skin's surface, causing visible dark spots.

To treat hyperpigmentation, a personalised and consistent approach is needed. Our anti-pigmentation products include lightening agents to block tyrosinase (the enzyme that creates melanin), antioxidants to fight free radicals, and ingredients to speed up skin cell turnover, removing pigmented cells. Using broad-spectrum sun protection is crucial to prevent new pigmentation during treatment.

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.

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.

Microbiome Balancing

Microbiome Balancing involves maintaining a healthy balance of microorganisms (bacteria, fungi, viruses) that live on your skin. Your skin's microbiome is crucial for protecting against pathogens, regulating pH, maintaining a healthy barrier, and ensuring optimal hydration. A balanced microbiome leads to clearer, healthier skin that’s more resilient to irritation and inflammation. Probiotics, prebiotics, and postbiotics are key ingredients that support a healthy microbiome. Probiotics introduce beneficial bacteria, prebiotics fuel the growth of good bacteria and help balance pH, and postbiotics enhance hydration and strengthen the skin barrier. This combination helps your skin stay healthy and vibrant.

Active Ingredients

LIFTISS®

LIFTISSÆ delivers a facial lifting and firming action. Its high molecular weight and film-forming properties allow it to effectively tighten facial contours, increase hydration by retaining water in the skin, and fill in wrinkles, visibly reducing their appearance. Additionally, LIFTISSÆ is rich in antioxidants, which help to protect the skin from environmental stressors and promote a youthful, radiant complexion.

Resveratrol

Resveratrol is a powerful antioxidant naturally found in red grapes. It contains high levels of polyphenols that help protect the skin from UV damage and environmental stressors by neutralising free radicals. By safeguarding cell DNA, it reduces inflammation and accelerates the skin's natural repair processes. Studies have shown that Resveratrol effectively reduces wrinkles, evens out skin tone, and improves skin firmness, leading to a brighter and more youthful complexion.

Cyclopeptide-5

Cyclopeptide-5 is a biomimetic peptide that mimics natural cellular communication to enhance skin repair and regeneration functions. it works by mimicking the natural signalling processes within skin cells, which are essential for repair and regeneration. When applied topically, it penetrates into the skin and interacts with receptors on cell surfaces, triggering mechanisms that enhance collagen and elastin production. These proteins are crucial for maintaining skin structure, firmness, and elasticity. By protecting collagen and elastin from degradation caused by ageing and UV exposure, Cyclopeptide-5 helps to preserve skin density and smoothness. It also supports the restructuring of the extracellular matrix, which can reduce the appearance of wrinkles, tighten facial contours, and restore youthful volume to the skin. Overall, Cyclopeptide-5 promotes a more resilient, rejuvenated complexion with improved elasticity and a reduction in visible signs of ageing.

SYN®-AKE

SYN®-AKE is a synthetic Tripeptide (a small molecule made up of three amino acids) designed to mimic the muscle-relaxing effects of snake venom. It works by inhibiting facial muscle contractions, which are responsible for forming expression lines like those around the eyes, forehead, and mouth. Similar to injectable treatments, SYN®-AKE smooths wrinkles and provides a noticeable lifting effect, particularly on sagging skin. This peptide is revolutionary in skincare for its ability to reduce the appearance of fine lines and wrinkles without the need for invasive procedures, helping to achieve a more youthful and rejuvenated complexion.

Auteur Hyaluronic Complex

Auteur's supercharged Hyaluronic Complex includes 5 different molecular weights of Hyalurons ranging from ultra-low too high for and instant boost of hydration, increased skin firmness and elasticity and long-lasting plumping results.

Auteur Hyaluronic Complex includes:

Cross-linked Hyaluronic Acid or Sodium Hyaluronate Crosspolymer, forms a three-dimensional mesh-like structure on the skin's surface. This unique structure acts as a breathable hydration barrier, helping to increase water retention by blocking trans epidermal water loss (TEWL). Cross-linked hyaluronic acid also has wrinkle-filling and skin-softening effect.

Medium Molecular Weight Hyaluronic Acid or Sodium Acetylated Hyaluronate (70-1,000 kDa?), occupies a unique position between high and low molecular weight hyaluronic acids, boosting skin hydration in the middle layers of the skin. It complements and enhances hydrating plumping results from famous Low and High Hyaluronic Acids, giving the skin even more suppleness and volume. It's in particularly good for those who have hollow faces due to density loss.

Low Molecular Weight Hyaluronic Acid or Sodium Hyaluronate, is a salt for derived from 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 desquamation, supporting the skin's natural renewal cycle.

Ultra-Low Molecular Weight? or Hydrolyzed Hyaluronic Acid? (<10 kDa), penetrates the skin the faster and the deepest compared to other forms. This provide ultra hydrating and plumping results. Additionally it can enhance collagen and elastin synthesis by stimulating fibroblast activity, resulting in firmer, denser and smoother looking skin.

Bioplasma™ FA

Bioplasma™ FA is a proprietary blend of Phytoplankton Extract and Arginine Ferulate aimed at detoxifying skin cells and protecting against environmental stressors. By effectively reducing Trans epidermal Water Loss (TEWL), it strengthens the skin's protective barrier, retains moisture, and diminishes the depth of wrinkles.

Saccharide Isomerate (PENTAVITIN)

Saccharide Isomerate, also known as PentavitinÆ, is a carbohydrate complex derived from plants that closely resembles the natural carbohydrates found in human skin. It serves multiple functions in skincare: first, it acts as a prebiotic, supporting a healthy balance of microorganisms on the skin's surface, which is crucial for maintaining skin health.

Secondly, Saccharide Isomerate functions as a powerful humectant. This means it attracts moisture from the environment and binds it to the skin, acting like a "water magnet." This ability helps to deeply hydrate the skin, making it appear plump, smooth, and intensely moisturised.

Studies have shown that Saccharide Isomerate can increase skin hydration levels for up to 72 hours after application, making it an effective ingredient for providing long-lasting hydration and maintaining skin moisture balance.

Complex of Peach Tree Leaf, Apple & Raspberry Extracts

Complex of Peach Tree Leaf, Apple & Raspberry Extract also known as is rich in Vitamin C & Alpha Hydroxy Acids, combining anti-pigmentation activity with lightening and exfoliating actions, to combat sun and age pigmentation. The marriage of these ingredients not only results in a more even complexion where future pigmentation is reduced, but existing pigmentation is lightened.

Arginine

Arginine, a naturally occurring Amino Acid in the skin, facilitates skin healing and the repair processes. It is used as a hydrating and collagen-boosting active, supporting collagen synthesis for firmer, plumper skin. Additionally, Arginine's antioxidant properties help neutralise free radicals, effectively combating signs of premature ageing.

Ectoin

Ectoin, alternatively spelled "ectoine," is a derivative of amino acids—organic compounds that serve as the fundamental building blocks of proteins and peptides. It functions to protect cellular structures in organisms exposed to extreme environmental conditions such as high salinity, extreme pressure, and severe temperature fluctuations. It achieves this by stabilising critical biomolecules, including enzymes, proteins, and nucleic acids. Ectoin forms a protective barrier around the skin, shielding it from environmental stressors such as ultraviolet (UVA) radiation and pollution. Furthermore, ectoin mitigates transepidermal water loss (TEWL) by reducing stress on the stratum corneum, the outermost layer of the skin, even in arid and challenging environments. Ectoin provides several scientifically backed benefits for skin health, including: - Its ability to reduce TEWL contributes to softer, smoother skin by maintaining optimal moisture levels and supporting a balanced skin microbiome. - It helps protect against UVA-induced damage, reducing hyperpigmentation and photoaging. - Ectoin alleviates skin sensitivity and stress, making it suitable for irritated or compromised skin.

    True magic in a bottle

    I got this for use on some fine lines on my forehead that have just begun to form but also my mother has been using it aswell. The difference for me is feeling more plump and hydrated and generally smoother in my face. The difference for my mother has been exceptional, the immediate lifting effects are noticable and the continued use has created lasting results. A tiny bit of this product goes a very long way i am excited to see the results over the next few months.
