Cosmetic Peptides

Cosmetic peptides are used in many cosmetic lotions and creams to promote anti-wrinkling and anti-aging. Utilizing over 15 years experience in peptide production, AAPPTec provides research- and cGMP-grade cosmetic peptides in any scale from milligrams to multi-kilograms. In addition to our catalog cosmetic peptides, AAPPTec can custom synthesize cosmetic peptides to a customer’s specifications.   

Signal Peptides

Cosmetic peptides typically can be classified into four categories: signal peptides, carrier peptides, neurotransmitter inhibitors and enzyme inhibitors. Signal peptides stimulate skin fibroblasts to produce more structural proteins, including elastin and collagen. Since aged skin has reduced levels of collagen and elastin, signal peptides helps the skin to look firmer and fuller.

Carrier Peptides

Carrier peptides deliver copper, magnesium, and other trace elements which aid in wound repair and enzymatic processes. These peptides are also called “penetrating peptides” and “membrane transduction peptides.” The trace elements they deliver improve collagen synthesis, skin elasticity and skin appearance, resulting in a reduction of fine lines and wrinkles.

Neurotransmitter Inhibitors

Neurotransmitter inhibitor peptides inhibit the release of acetylcholine through a variety of interactions. By inhibiting the release of the neurotransmitter, these peptides attenuate the contraction of facial muscles causing wrinkles to relax. Some types of wrinkles may be reduced by appoximately 30%. One example of a neurotransmitter inhibiting peptide utilized in cosmetics is Argreline which inhibits synthesis of the SNARE receptor.

Enzyme Inhibitors

ACE inhibitor peptides relax blood vessels and can increase lymphatic drainage. In cosmetic formulations, they may reduce the accumulation of fluid and relieve puffiness, as under the eyes.
