Global Anti-Ageing Serum
Benefits
The Demain Beauty Global Anti-Ageing Serum is a lightweight, bi-phase treatment designed to restore skin balance, strengthen the barrier and support long-term skin longevity, combining microbiome-rebalancing ferments, prebiotic actives and deep hydration to improve resilience, reduce inflammation and protect against premature ageing.
Lactobacillus Ferment, Alpha-Glucan & Yacon Root acts as the hero postbiotic complex — helping to rebalance the skin’s microbiome, strengthen its natural defence mechanisms and reduce inflammation, supporting healthier, more resilient skin while contributing to long-term anti-ageing through improved skin function.
Radish Root Ferment acts as the microbiome protector — reinforcing the skin’s natural bacterial defences, helping to inhibit harmful microorganisms and supporting clarity, calmness and overall skin integrity.
Glycerin and Sodium Hyaluronate form the hydrating complex — drawing hydration into the skin, improving water retention and visibly enhancing plumpness, suppleness and comfort, helping to soften the appearance of fine lines caused by dehydration.
Milk Thistle Oil creates the antioxidant lipid foundation — rich in essential fatty acids and protective compounds, it helps defend against oxidative stress, reduce inflammation and reinforce the skin barrier, supporting a slower, more balanced ageing process.

Ingredients
SteviosideAnti-Wrinkle · Skin Barrier Strengthening
Stevioside has soothing, antioxidant and skin-conditioning properties. It helps to reduce low-grade inflammation and oxidative stress within the skin, supporting a calmer, more balanced complexion while contributing to long-term skin resilience. Although sometimes associated with mild muscle-relaxing properties, its role is primarily to comfort, protect and support overall skin functionLactobacillus FermentMicrobiome Balancing · Balancing the Skin pH · Anti-Inflammatory
Lactobacillus Ferment, a probiotic derived from the fermentation of Lactobacillus bacteria that focuses on microbiome balancing. A balanced microbiome is crucial for healthy skin as it strengthens the skin's barrier, reduces inflammation, and improves hydration, resulting in healthier and more resilient skin. It also helps maintain optimal pH levels and protects against infections.Milk Thistle OilSkin Barrier Strengthening · Antioxidant · Nourishing
Milk Thistle Oil actively supports cellular reconstitution and barrier repair, replenishing the skin's hydrolipidic film and restoring elasticity and suppleness to skin that has become dry, depleted or visibly aged. Its high Vitamin E content neutralises free radical damage and protects against environmental oxidative stress, while its omega 6 fatty acids deeply nourish and strengthen the skin's natural resilience over time.GlycerinHydrating
Glycerin is a potent humectant commonly used in skincare for its powerful hydrating properties. It works by attracting water molecules from the atmosphere and retaining them in the deeper layers of the skin, effectively boosting hydration reservoir. This helps to plump up the skin, resulting in reduced dehydration lines and a soft, supple complexion.Alpha GlucanMicrobiome Balancing
Alpha-Glucan works to support and rebalance the skin’s microbiome rather than act as a direct corrective active. It selectively nourishes beneficial bacteria while limiting the growth of undesirable microorganisms, helping to restore microbial equilibrium, reduce sensitivity and strengthen the skin barrier over time. By reinforcing this ecosystem, it improves the skin’s resilience, supports clearer, calmer skin and enhances overall functionRadish Root FermentMicrobiome Balancing
Radish Root Ferment acts as a targeted prebiotic — selectively feeding and strengthening beneficial bacteria on the skin's surface while simultaneously inhibiting the growth of pathogenic microorganisms. This dual action supports a more balanced, diverse and resilient skin microbiome, creating the conditions in which the skin's own natural defence and repair mechanisms can function optimally.Yacon RootSkin Barrier Strengthening · Microbiome Balancing · Anti-Redness
A prebiotic-rich extract derived from the Yacon plant, exceptionally high in fructooligosaccharides (FOS) — naturally occurring sugars that selectively feed and diversify beneficial bacteria on the skin's surface. By nourishing the skin's microbiome rather than introducing new bacteria directly, it creates the ideal environment for a balanced, resilient skin ecosystem, helping to regulate excess sebum, calm reactivity and reinforce the barrier function.Low Molecular Weight Hyaluronic AcidHydrating · Plumping
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. Additionally, it 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.
