Regenerating

Regenerative benefits work to restore and renew your skin at a cellular level. By stimulating cell turnover and boosting collagen and elastin production, they help repair damage, diminish fine lines and wrinkles, and improve overall skin texture. The result is a rejuvenated, firmer, and more youthful complexion that radiates vitality.

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.

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.

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.

Skin Barrier Strengthening

Strengthening your skin barrier involves replenishing the key elements in the top layer of your skin (stratum corneum), leading to a stronger and healthier barrier. These essential elements include lipids (ceramides, fatty acids, and cholesterol) and Natural Moisturizing Factors (amino acids, hyaluronic acid, etc.). Various factors, such as incorrect skincare use, seasonal changes, and aesthetic treatments, can damage your skin barrier. When this happens, your skin loses excess water through Trans Epidermal Water Loss (T.E.W.L) and becomes less capable of defending against environmental stressors, resulting in dryness, sensitivity, and irritation.

A healthy skin barrier is crucial for overall skin health as it helps prevent hydration loss, protects against environmental damage, and reduces the risk of skin conditions like eczema and acne. By strengthening your skin barrier, you ensure your skin remains well-hydrated, resilient, and protected.

Soothing

When your skin is sensitive or weakened due to genetics, skin conditions, using incorrect skincare products, or harsh weather, it needs extra care to repair and strengthening. Soothing ingredients with anti-inflammatory properties can reduce redness and irritation while strengthening the skin barrier, making it more resilient and protected against external aggressors.

Anti-Redness

Anti-Redness skincare is all about reducing and preventing facial or body redness, which can result from irritation, skin conditions, compromised barriers, and hormonal changes. A targeted approach with multiple strategies works best for tackling redness. Anti-Redness formulations include active ingredients that soothe and strengthen your skin barrier. Their anti-inflammatory and antioxidant properties calm inflammation and protect against environmental irritants. Additionally, these ingredients have vasoconstrictive properties, meaning they reduce blood vessel dilation to lessen redness. Together, these actions help achieve a more even-toned, balanced complexion that's less prone to redness flare-ups.

Tridecapeptide‑1

A Bio-Reprogramming Peptide is an advanced cell-signaling active that helps aging skin behave more like young skin by “talking” to skin cells; it works by binding to cell receptors and activating gene pathways that control skin repair, collagen production, inflammation. It also improves the efficacy of other actives, instead of just sitting on the surface, it sends instructions that help cells regenerate and reduce internal stress. The results are firmer, smoother, brighter, better-hydrated skin with improved elasticity and visible reduced wrinkles.

Biomimetic Peptide & Red Clover Extract

Biomimetic Peptide & Red Clover Extract help minimise hair loss by stabilising hormonal fluctuations, specifically in Dihydrotestosterone (DHT) levels, which are linked to hair loss. They also reduce scalp irritation and enhance cell renewal processes to normalise hair growth cycles, thereby reducing excessive hair loss and stimulating new hair growth.

Hydrolyzed Collagen

Hydrolyzed Collagen refers to collagen that has been broken down by enzymatic hydrolysis into amino acids and smaller peptides for deeper and better absorption. Amino Acids and Peptides assist in skin repair processes and encourage collagen synthesis resulting in firmer and more resilient skin. Hydrolyzed Collagen also act as a potent humectant, attracting and retaining water in the skin for hydrated, plump complexion.

Argireline

Argeriline also known as Acetyl Hexapeptide-8 is a neurotransmitter-inhibiting peptide, meaning it can minimise muscle contractions to provide injection-free wrinkle smoothing results. It can also support collagen in the skin, helping to persevere skin firmness.

Vitamin B3 (Niacinamide)

Vitamin B3 also known as Niacinamide, is versatile and highly effective ingredient with many benefits. It helps to strengthen skin barrier function and increase water retention by increasing natural ceramide production. It's anti-inflammatory and sebum regulating properties soothe, repair and balance irritated, weakened and acne prone skins. Niacinamide is also a potent antioxidant with protective and brightening properties helping to restore skin's natural glow.

Biologically Optimised Guava

A bioactive extract engineered to counteract cellular senescence—one of the primary drivers of skin ageing. By targeting and reducing the accumulation of senescent cells, it minimises chronic inflammation, a key factor in skin dullness and degradation. In addition, its anti-inflammatory properties help calm sensitised or stressed skin, reducing visible redness while strengthening the skin’s natural defence and resilience for healthier-looking skin over time.

Low Molecular Weight Hyaluronic Acid (Sodium Hyaluronate)

Low Molecular Weight Hyaluronic Acid (LMW-HA) is a smaller, more penetrative form of hyaluronic acid. Unlike high molecular weight forms that primarily hydrate the skin’s surface, LMW-HA has the ability to penetrate deeper into the epidermis, where it attracts and binds water to maintain optimal moisture levels from within. This deep hydration helps improve skin elasticity, firmness, and smoothness, while reducing the appearance of fine lines and dehydration-induced wrinkles. Additionally, LMW-HA supports skin barrier repair and enhances overall suppleness, making the complexion look plumper and more resilient. It is ideal for dehydrated, dull, or mature skin, and especially those in need of long-lasting hydration and improved texture.

Lecithin

Lecithin is a deeply soothing ingredient that helps strengthen the skin’s barrier and protects against dryness and irritation. Rich in nourishing Fatty Acids, Glycerol, and Phospholipids (the building blocks of healthy cells) it also helps to repair weakened and damaged skins while locking hydration.

Spotlight

Hydrolysed Collagen

Hydrolysed Collagen is a form of collagen broken into smaller peptides for easier absorption into the skin, offering enhanced elasticity and hydration. Collagen is a naturally occurring protein in our bodies, responsible for maintaining skin’s structure, firmness and elasticity. Utilising it as a bioavailable ingredient helps to reduce fine lines and wrinkles while promoting a smoother, youthful complexion. By supporting the skin’s natural collagen production, it improves firmness and resilience with enhanced skin texture, tone and an overall radiant glow. An effective solution in maintaining skin health, it’s a vital component in anti-ageing skincare formulations for firmer, fresher skin.
