Description

Acetyl Heptapeptide-4 is a synthetic peptide used in cosmetic formulations for its potential anti-aging and skin-rejuvenating properties. It consists of a chain of seven amino acids, with an acetyl group attached to enhance stability and skin penetration.

Chemical Composition and Structure

Acetyl Group: A chemical modification that enhances the peptide’s stability and penetration through the skin.
Heptapeptide: Composed of seven amino acids. The specific sequence of these amino acids can vary depending on the peptide’s design, providing unique properties.

Physical Properties

Appearance: Usually a white or off-white powder, though it may be formulated into a liquid depending on the product.
Odor: Typically odorless or slightly aromatic depending on the formulation.
Solubility: Generally soluble in water or specific solvents used in cosmetic formulations.

Production Process

Chemical Synthesis: The heptapeptide is synthesized through a chemical process that links seven amino acids with an acetyl group.
Purification: After synthesis, the peptide is purified to remove any impurities and ensure the product's potency.
Formulation: The purified peptide is incorporated into cosmetic products such as creams, serums, and lotions.

Applications

Cosmetics: Used in anti-aging products to enhance skin firmness and reduce the appearance of fine lines and wrinkles.
Skincare Treatments: Included in serums and treatments to improve skin texture and elasticity.
Personal Care: Found in a variety of beauty products for its potential skin-rejuvenating benefits.

Cosmetic Benefits

Anti-Aging: Helps to reduce the appearance of wrinkles and fine lines by promoting skin firmness and elasticity.
Skin Rejuvenation: Improves skin texture and tone, making the skin appear smoother and more youthful.
Firming: Contributes to the tightening and toning of the skin, enhancing overall skin appearance.

Safety

Acetyl Heptapeptide-4 is generally regarded as safe for use in cosmetics and personal care products when used as directed.

Environmental and Safety Considerations

Sustainability: Production processes should consider environmental impacts and adopt sustainable practices.
Regulation: The use of Acetyl Heptapeptide-4 must comply with cosmetic regulations to ensure safety and efficacy.

INCI:


Humectant. Hygroscopic compound used to minimise water loss in the skin and to prevent it from drying out by facilitating faster and greater absorption of water into the stratum corneum of the epidermis. The epidermis is the most superficial of the three layers that make up human skin (epidermis, dermis and hypodermis) and is the layer that maintains hydration in all three layers. In turn, the epidermis is composed of five layers: horny, the most superficial, granular, spinous, shiny, and basal. Humectants have the ability to retain the water they attract from the air in the stratum corneum and have the function of moisturising the skin. They are best used before emollients, which are oil-based.

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.
