Acetyl Tetrapeptide-22 is a synthetic peptide used in cosmetics for its anti-aging and skin-enhancing properties. This peptide is known for its role in strengthening the skin's defenses and improving its resilience.

Chemical Composition and Structure

Structure: Acetyl Tetrapeptide-22 consists of a chain of four amino acids with an acetyl group attached to the N-terminal end, which enhances its stability and efficacy.
Chemical Formula: The specific sequence of amino acids and the acetyl group give the peptide unique properties for skin care.

Physical Properties

Appearance: Typically available as a white or clear powder, depending on the formulation.
Odor: Generally neutral, does not affect the final fragrance of the cosmetic product.

Production Process

Synthesis: Produced through solid-phase peptide synthesis (SPPS), a method that allows precise creation of the peptide sequence.
Purification: Purified using advanced techniques such as high-performance liquid chromatography (HPLC) to ensure high purity and activity.
Formulation: Incorporated into cosmetic products to maintain its stability and achieve maximum skin benefits.

Applications

Skincare: Used in creams, serums, and lotions to strengthen the skin barrier, improve skin elasticity, and reduce signs of aging.
Cosmetics: Included in products aimed at enhancing skin resilience and providing additional protection against environmental factors.

Cosmetic Benefits

Strengthening the Skin Barrier: Helps improve the skin's barrier function, increasing its protection against environmental stressors.
Anti-Aging: Contributes to visibly reducing signs of aging and improving skin firmness.
Improving Elasticity: Promotes more elastic and toned skin, enhancing its texture and comfort.

Safety

This ingredient is generally regarded as safe for use in cosmetics and personal care products when used as directed. Individuals with allergies or sensitivities to peptides should carefully check ingredient lists.

Environmental and Safety Considerations

Sustainability: As a synthetic peptide, it has a reduced environmental impact compared to natural extracts.
Regulation: Compliant with cosmetic safety regulations to ensure safe use in topical applications.

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.
