Hyaluronic acid serum hydrates the skin to reduce wrinkles, with varying HA molecular weights impacting penetration and potential irritation.
Hyaluronic acid serum is a topical product designed to hydrate and plump the skin. It contains hyaluronic acid, a naturally occurring substance in the body that acts as a humectant, drawing moisture into the skin. This leads to improved hydration, reduced appearance of wrinkles, and potentially faster wound healing. Serums typically contain varying molecular weights of HA, impacting their penetration depth and effect. Side effects are generally mild, involving potential irritation, but allergic reactions are possible.

Common Dosage
Concentrations in serums typically range from 0.1% to 2% Hyaluronic Acid, applied topically once or twice daily.

hybrid
Production Process
Hyaluronic acid (HA) for serums is typically produced through microbial fermentation, often using *Streptococcus zooepidemicus* bacteria. These bacteria are cultured in a nutrient-rich broth. The HA produced is then extracted, purified, and processed to various molecular weights for different applications. Some smaller HA molecules might be produced synthetically.

Outside BodyPotential Benefits
Skin hydration is essential for maintaining skin elasticity, barrier function, and overall appearance. It reduces fine lines, protects against environmental stressors, and improves skin smoothness and suppleness.
Accelerates and supports the body's natural wound repair processes. This includes reducing inflammation, promoting collagen synthesis, increasing cell proliferation, and facilitating angiogenesis, leading to faster wound closure, reduced scarring, and decreased infection risk.
Wrinkle reduction is achieved through Matrixyl stimulating collagen production and Argireline inhibiting facial muscle contractions. This combination aims to minimize the appearance of fine lines and wrinkles, offering a more youthful complexion.
Hyaluronic acid hydrates the skin, improving its elasticity and making it appear firmer and more supple. This is achieved through water retention, which enhances the skin's ability to stretch and recoil, reducing the appearance of fine lines and wrinkles.
Possible Side Effects
Skin irritation involves symptoms like redness, itching, and rashes due to contact with irritants, allergens, or environmental factors. Severity varies based on the cause, individual sensitivity, and affected area; persistent cases may lead to secondary infections.
Allergic reactions are hypersensitivity responses to allergens, ranging from mild skin irritation to life-threatening anaphylaxis. Symptoms vary widely and are caused by an immune response.
