Composed of chains of amino acids, peptides are the building blocks of proteins. Perhaps you’ve already heard that collagen is one of the most important proteins in our skin because it helps our skin to maintain young and energetic. Influenced by age and environmental factors like the sun and stress, collagen would decrease, which accounts for the emergence of wrinkles. Peptides to be used in skin care can send a signal to collagen and prompt the formation of new collagen. Guided by this principle, various types of cosmetic peptide products have been designed and marketed. Next, we are going to focus on anti-pigmentation peptide and eye care peptide.
Anti-pigmentation peptideOur skin color is determined by the melanocyte which produce melanin in dermis layer of our skin. To be more specific, melanin is formed by the oxidation and polymerization of the amino acid tyrosine. When people becomes older, more melanin would be found. Anti-pigmentation peptide is therefore the best natural dark spot corrector that can greatly lighten the spots without damaging your skin.
Researches proved that some polypeptides delivered into human skin might have certain anti-pigmentation effects. For example, a tetrapeptides PKEK (Pro-Lys-Glu-Lys) has been found to have skin whitening potentials. In a study where 39 Caucasian women were enrolled, facial pigment spots significantly faded after 6 weeks under a combined therapy of PKEK another skin whitener called sodium ascorbyl phosphate (SAP).
Using a lightening hyperpigmentation cream is necessary for nearly everyone, even those who don’t have spots yet. Sometimes you might not notice that your skin has already been damaged. In most cases, your face is especially vulnerable to age spots as it is more frequently exposed to the elements than any other part of your body. With the help of anti-pigmentation peptides, a more even, youthful complexion would be maintained in spite of the aging issue.
Other ingredients that could be combinedly used in anti-pigmentation management are dipeptide and hexapeptide. Dipeptide can even the skin tone and make your skin look lighter and younger. Hexapeptide fights wrinkles that are caused by facial muscle movement. Both are helpful in preventing pigmentation from forming.
Eye Care peptideIn skin care, eye care is of great importance as the skin around eye area is particularly fragile. Without proper care, problems like circles, eyelid bags, and puffiness, as well as fine lines and deep wrinkles would occur. All these are common signs of periorbital skin aging. To reduce wrinkles, Botox has been widely administered in the United States. It’s effective and more than 2.6 million people tried in 2014. However, its serious side effects could not be neglected. Therefore, the application of Botox is often questioned regarding to safety issues. In fact, there are some alternative products that could be chosen for periorbital skin rejuvenation in skin care, such as Acetyl hexapeptide-3, a safer replacement of Botox.
In addition to Acetyl hexapeptide-3, there are some other eye care peptides such as Acetyl Tetrapeptide-5, Dipeptide-2 and Palmitoyl Tetrapeptide-7. Acetyl Tetrapeptide-5 behaves well in reducing puffiness under the eyes. It is also believed that Acetyl tetrapeptide-5 can help skin maintain a smooth resilience and ultimately contribute to a more youthful appearance. Dipeptide-2 is composed of valine and tryptophan and often serves as a skin conditioning agent. It is believed to be capable of improving lymphatic circulation.
