Description

Acetyl sh-Tetrapeptide-1 is a synthetic peptide used in cosmetic formulations, valued for its anti-aging and skin-reinforcing properties. This peptide is designed to stimulate collagen production and improve skin elasticity, contributing to a more youthful and toned appearance.

Chemical Composition and Structure

Structure: Acetyl sh-Tetrapeptide-1 consists of a sequence of four amino acids with an acetyl group attached to the N-terminal end of the peptide chain. This acetyl group enhances the peptide's stability and efficacy in cosmetic formulations.
Chemical Formula: Chemical modifications include an alteration of the peptide's structure to increase its affinity and activity in skin tissues.

Physical Properties

Appearance: Typically appears as a white or off-white powder, or in solution, depending on the formulation.
Odor: Generally neutral, with slight variations possible based on other ingredients in the formulation.

Production Process

Synthesis: Created through solid-phase peptide synthesis (SPPS), which involves assembling the peptide chain amino acid by amino acid.
Purification: The peptide is purified using techniques such as high-performance liquid chromatography (HPLC) to ensure purity and effectiveness.
Formulation: The purified peptide is incorporated into cosmetic products, maintaining stability and efficacy in various formulations.

Applications

Skin Care: Used in anti-aging serums, creams, and lotions to support collagen production and enhance skin firmness and elasticity. Ideal for products aimed at reducing wrinkles and improving overall skin appearance.
Cosmetics: Included in formulations to improve skin hydration and structure.

Cosmetic Benefits

Anti-Aging: Promotes collagen production, visibly reducing wrinkles and fine lines.
Firming: Enhances skin elasticity, improving firmness and tone.
Hydrating: Contributes to maintaining skin hydration and improves the skin barrier function.

Safety

This ingredient is generally regarded as safe for use in cosmetics and personal care products when used as directed. Individuals allergic to peptides or with very sensitive skin should be cautious.

Environmental and Safety Considerations

Sustainability: As a synthetic peptide, it has no direct impact on natural resources and is produced with attention to environmental standards.
Regulation: Acetyl sh-Tetrapeptide-1 is regulated under cosmetic safety standards to ensure it is safe for topical use.

INCI Functions:


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
