Superlative Serum Phi
Benefits
The Auteur Superlative Serum Phi is a high-performance anti-ageing treatment that restores firmness, smooths wrinkles and improves skin resilience. It uses regenerative bio-reprogramming peptides to activate youthful cell behavior, support structured matrix repair and reduce internal skin stress.
Lifting peptides soften expression lines, while stabilising actives including Niacinamide optimise hydration, calm inflammation and balance pigment responses. The serum delivers these signals into the upper epidermis, improving communication between renewal cells and collagen-producing fibroblasts, resulting in firmer, smoother, brighter and optimally hydrated skin.

Ingredients
Tridecapeptide‑1Active Delivery · Regenerating · Anti-Wrinkle
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.LecithinSkin Barrier Strengthening · Anti-Redness · Nourishing
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.Hydrolyzed CollagenFirming & Lifting · Plumping
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.ArgirelineFirming & Lifting · Plumping · Injectable Effect
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.Biologically Optimised GuavaRegenerating · Anti-Wrinkle · Skin Barrier Strengthening
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 AcidPlumping · Hydrating
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.Vitamin B3 (Niacinamide)Skin Barrier Strengthening · Anti-Inflammatory
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.
