Pentapeptide-3 (Vialox) is a synthetic bioactive polypeptide composed of five amino acids. Favored for its mild yet potent properties, it is widely incorporated into high-end cutaneous repair and anti-aging skincare formulations. This ingredient exerts dual mechanisms of action: neuromodulation and cutaneous repair. On one hand, it competitively binds to acetylcholine receptors in cutaneous nerves to gently mitigate cutaneous neurogenic stress responses. On the other hand, it mimics fragments of cutaneous matrix proteins, activating dermal fibroblast activity and stimulating the synthesis of collagen and hyaluronic acid. Additionally, it features excellent water solubility, strong formulation stability and superior compatibility. It can be combined with moisturizing, age-defying and oil-controlling actives. It delivers independent anti-wrinkle and repairing benefits, and can also serve as a formulation buffer to enhance the gentleness of skincare products. It is an all-round skincare peptide balancing cutaneous repair, homeostasis maintenance and age-defying effects.

Additional Benefits by Skin Type
Sensitive, Thin Complexion & Fragile Periorbital Skin: Neuronal soothing, alternative to harsh skincare actives
The primary concerns of sensitive thin complexion and fragile periorbital complexion lie in low neuronal sensitivity thresholds and impaired cutaneous barrier function. Such complexion is highly susceptible to external irritants, developing redness, stinging, burning, dry itch and other discomforts. Furthermore, the periorbital region contains very few sebaceous glands; its cutaneous thickness is merely one-third of that on other facial areas, resulting in extremely low tolerance to highly active and irritating skincare ingredients.Conventional age-defying and brightening actives carry notable drawbacks: retinoids tend to compromise the cutaneous barrier and trigger dryness, peeling, redness and stinging; high-concentration vitamin C possesses strong acidity that irritates cutaneous nerve endings and aggravates sensitivity. Pentapeptide-3 acts as an ideal substitute for these harsh ingredients, catering to the daily care demands of fragile complexion.
Boasting a unique neuromodulatory mechanism, vialox precisely blocks cutaneous neurogenic stress responses and lowers cutaneous neuronal sensitivity thresholds. It relieves sensitive symptoms including redness, stinging and burning at the source, alleviating persistent flushing triggered by heat, wind and seasonal shifts in sensitive complexion. For fragile periorbital complexion, this mild, non-irritating peptide imposes no osmotic pressure. It effectively improves redness and dryness induced by nervous tension and external stimuli around the eyes, eases micro-contractions of periorbital muscles, and prevents the formation of dryness-related and stress-induced fine lines.Compared with barrier-repairing ingredients such as panthenol and ceramides, vialox repairs not only the physical cutaneous barrier but also the neural barrier, achieving dual effects of barrier restoration and neuronal stabilization. It fundamentally ameliorates hypersensitivity and intolerance in fragile complexion. Long-term use gradually elevates cutaneous tolerance, enabling gentle age-defying, brightening and repair without the risk of cutaneous damage caused by high-potency aggressive formulations.
Oily & Acne-Prone Complexion: Anti-inflammatory stabilization, compatible with oil-control and anti-wrinkle formulations
Oily and acne-prone complexion is characterized by overactive sebaceous secretion, elevated inflammatory factors and predisposition to pore clogging. Meanwhile, most individuals with this cutaneous type face challenges in age-defying care: traditional oil-controlling ingredients are often drying and irritating, while common age-defying actives may induce breakouts and worsen inflammation. This creates a dilemma in balancing oil regulation, acne control and wrinkle reduction.It is free from comedogenic risks, delivers mild anti-inflammatory effects and synergizes oil control and age-defying benefits, making it an ideal functional ingredient to resolve skincare conflicts for oily and acne-prone complexions.
In terms of cutaneous compatibility, it has a stable molecular structure and a lightweight, non-greasy texture. It does not clog pores or trigger closed comedones and breakouts, matching the metabolic characteristics of oily and acne-prone complexion. It effectively suppresses the activity of cutaneous inflammatory factors, relieves inflammatory redness and post-acne erythema, alleviates swelling and burning after acne flare-ups, and accelerates recovery of inflamed complexion.In formulation design, vialox works seamlessly in oil-controlling anti-wrinkle serums. When combined with niacinamide, zinc ions, salicylic acid and other oil-regulating and anti-acne agents, it neutralizes part of the irritation of co-ingredients, preventing barrier damage caused by excessive exfoliation from oil-control actives, and compensates for the lack of age-defying efficacy in conventional oil-regulating products.Long-term use of skincare products containing vialox helps balance sebum levels and stabilize cutaneous inflammation. It also improves rough texture, fine lines and enlarged pores stemming from lipid oxidation and cutaneous laxity, realizing integrated oil control, anti-inflammation and age-defying effects suited for long-term refined skincare routines for oily and acne-prone complexion.
Dry complexion: Boosted moisturization, improvement of dry lines and tightness
Core issues of dry complexion include insufficient stratum corneum hydration, inadequate sebum secretion and impaired water retention capacity. Dryness, tightness, flaking and frequent fine dry lines are common complaints, especially during seasonal transitions and dry autumn and winter conditions. Dehydration-induced cutaneous stress turns transient dry lines into permanent wrinkles and accelerates cutaneous aging. Most standalone moisturizers only hydrate the cutaneous surface without enhancing endogenous water retention. Pentapeptide-3 assists in optimizing dry cutaneous conditions by nurturing the stratum corneum, and generates long-lasting moisturizing and anti-dry-line effects when paired with hyaluronic acid.
It gently conditions the stratum corneum, moderately enhancing its water storage capacity, repairing dry, damaged corneal structures and reducing transepidermal water loss to ease baseline dryness and tightness in dry complexion. It exhibits outstanding formulation synergy with hyaluronic acid: hyaluronic acid rapidly delivers hydration to both superficial and deep complexion layers, while vialox stabilizes the stratum corneum barrier to lock in supplemented moisture and avoid rapid evaporation, significantly prolonging cutaneous water retention.Combined application targets typical concerns of dry complexion such as seasonal peeling, morning tightness, expression-related dry lines and periorbital dry lines. It softens rough keratin and restores a smooth, hydrated complexion. Furthermore, it is mild and free from drying or defatting side effects that worsen barrier impairment. It satisfies daily moisturization, repair and entry-level age-defying demands for extremely dry and combination dry complexion, tackling the root cause of dehydration-associated aging.
Mature Tolerant Complexion: Synergistic enhancement in formulations for dual anti-aging effects
Mature tolerant cutaneous features intact barriers and high resistance. Its primary skincare priority is potent age-defying, targeting dynamic wrinkles, static fine lines, complexion sagging and collagen depletion. Single age-defying ingredients deliver limited results. It demonstrates remarkable formulation compatibility. When combined with collagen peptides, retinoid derivatives and other mainstream anti-aging actives, it enables complementary mechanisms to achieve powerful dual age-defying outcomes: muscle relaxation plus collagen neo-synthesis, perfectly meeting mature skin's age-defying requirements.
From the perspective of age-defying mechanisms, vialox focuses on wrinkle reduction via neuromuscular soothing.
It blocks abnormal signal transmission between cutaneous nerves and muscles, inhibits frequent micro-contractions of facial muscles, rapidly fades dynamic expression lines including forehead lines, crow's feet and nasolabial folds, and prevents dynamic wrinkles from developing into static creases.Collagen peptides primarily supply exogenous collagen and stimulate dermal collagen synthesis; retinoid derivatives accelerate keratin turnover, promote collagen regeneration, diminish static fine lines and firm sagging complexion.The ternary combination establishes a comprehensive age-defying system: It relaxes tense facial muscles and intercepts wrinkle formation at the source; retinoid derivatives slough off aged keratin and activate cutaneous regeneration; collagen peptides replenish collagen deficits and lift lax complexion. Their synergistic action quickly improves superficial fine lines and expression wrinkles in mature complexion, replenishes collagen in the dermis, elevates cutaneous elasticity, and alleviates deep aging signs such as sagging, dullness and rough texture. For tolerant complexion, this composite formulation carries minimal over-stimulation risks while remaining highly effective and gentle. Consistent use markedly decelerates cutaneous aging and supports refined, full-spectrum anti-aging care.
Discovery History
Research and development of the product took place amid the boom of bioactive peptide studies in the early 21st century. It is a functional skincare peptide developed by researchers using biomimetic synthesis technology to address complexion anti-aging and repair demands.
Early age-defying skincare ingredients mostly relied on irritating chemical agents, limited by severe side effects and narrow cutaneous compatibility.
After 2000, European and American bioscience teams launched research into skincare applications of mild biomimetic peptides. By simulating active fragments of native human cutaneous proteins, researchers screened a pentapeptide structure compatible with cutaneous cells that combines neuromodulatory activity and collagen-stimulating functions, successfully synthesizing vialox.
In 2007, relevant research teams officially published experimental data verifying its skincare efficacy, confirming its core functions of collagen promotion, soothing, anti-inflammation and gentle age-defying. The ingredient was gradually commercialized afterwards and widely adopted in high-end repair and age-defying skincare formulas, establishing itself as one of the classic ingredients in peptide skincare.
