Have you heard of peptides ? They are the latest generation ingredients in the world of anti-aging cosmetics, true allies for younger and more toned skin.
Peptides are naturally found in our bodies and play a key role in keeping skin toned, elastic and firm.
What are peptides?
Think of peptides as tiny messengers that communicate with your skin cells. When multiple peptides join together, they form proteins like collagen, elastin, and keratin. These proteins are essential to our skin because they give it tone and elasticity, fighting wrinkles and sagging skin.
Why include peptides in cosmetics?
Applied to the skin, peptides act in several ways:
- They stimulate the production of collagen and elastin: these two elements are responsible for the structure and support of the skin. With age, their production decreases, causing wrinkles and skin laxity. Peptides help stimulate the production of these proteins, making the skin firmer and more compact.
- Reduce wrinkles and fine lines: Peptides can help smooth out wrinkles and fine lines, giving skin a smoother, more even appearance.
- Improve skin elasticity and tone: peptides help make the skin more elastic and toned, counteracting the signs of aging.
- Protects skin from free radical damage: Free radicals are unstable molecules that can damage skin cells. Peptides help protect skin from free radical damage, preventing premature aging.
Peptides in cosmetics: classification and functions
The ones you find in cosmetics are called biomimetic peptides , which imitate the action of natural peptides produced by our body.
Signal Peptides
They stimulate or inhibit processes such as the production of collagen and elastin, making the skin firmer and more toned.
- Palmitoyl Tripeptide-1 and Palmitoyl Tripeptide-5 : Stimulate collagen synthesis and inhibit the enzymes that degrade it.
- Palmitoyl Tetrapeptide-3 : Stimulates the synthesis of collagen and glycosaminoglycans.
- Palmitoyl Pentapeptide-4 : Stimulates the production of collagen and elastin, making the skin firmer.
- Palmitoyl Heptapeptide-5 : Stimulates collagen synthesis.
Enzyme inhibitory peptides
They slow down collagen degradation or reduce pigmentation.- Oligopeptide-20 : Activates wound healing mechanisms.
- Dipeptide-2 and Acetyl Tetrapeptide-5 : Improve lymphatic drainage, reducing bags and dark circles.
Neurotransmitter inhibitory peptides
By reducing communication between nerves and muscles, they reduce expression lines.- Palmitoyl Hexapeptide-19 : Reduces the contraction of mimic muscles, diminishing expression wrinkles.
- Acetyl-hexapeptide-8 : Works as a muscle relaxant, reducing the visibility of wrinkles after a few days of use.
- Palmitoyl Pentapeptide-3 : Reduces muscle contraction and stimulates the production of collagen and hyaluronic acid.
- Dipeptide Diaminobutyroyl Benzylamide Diacetate : Penetrates deeply into the skin, acting on wrinkles caused by facial movements.
How to choose a cosmetic with peptides?
As we have seen, there are different types of peptides available, each with its own function.
For an even more effective action on the skin, I recommend you choose a product that combines different peptide technologies, so that it can act on multiple fronts for the well-being of your skin.
B-Like Serum Yuniwa Cosmetics is a face serum with 4 different peptide technologies for:
- reduce the depth of wrinkles
- stimulate collagen synthesis
- inhibit muscle contractions to relax the face
In addition to peptides, this anti-aging face serum contains precious hydrating, plumping and protective ingredients such as:
- cross-linked hyaluronic acid, with plumping and hydrating action
- mix of amino acids, which keep the skin healthy and luminous by protecting it from free radicals
- brewer's yeast extracts , which protect the skin barrier to reduce blemishes and imperfections
B-Like Serum is a serum suitable for all skin types, oil-free, fragrance-free, plumps and smoothes the skin for a healthier and brighter appearance.
