Touted as the key ingredient to combat the signs of aging , peptides are renowned for their powerful action on skin aging . Explore all the visible results of peptides on the skin : firmness, repair, hydration, and wrinkle reduction. Nooance-paris reveals its beauty tips for incorporating this anti-aging active ingredient into your skincare routine and revealing your skin's natural radiance.
What is the role of peptides in cosmetics?
What is a peptide and how does it work on the skin?
Peptides are molecules composed of chains of amino acids. They promote the formation of proteins essential for healthy skin: collagen, elastin, and keratin. Without the effects of peptides, the skin loses its elasticity, texture, and radiance.
Why use peptides?
In the field of cosmetic care, peptides are increasingly used as an anti-aging ingredient to slow the signs of aging. Topical application of peptides helps compensate for the natural decline in their production with age.
Integrating peptides into cosmetics has many benefits: they stimulate the production of collagen and hyaluronic acid, they improve the elasticity and firmness of the skin, they prevent the appearance of wrinkles by accelerating cell renewal, they preserve suppleness and smooth the skin's texture.
The different types of peptides in cosmetics
- Signal peptides: These stimulate the production of certain proteins such as collagen and elastin.
- Enzymatic peptides, or enzyme inhibitors : they slow down the breakdown of collagen linked to skin aging.
- Transporter peptides or oligopeptides : they transport the active ingredients and metals essential for maintaining healthy skin (copper, zinc, silicon).
- Neurotransmitter inhibitor peptides : they act on muscle contractions with a "botox-like" effect by reducing the release of toxins that cause expression lines (crow's feet around the eyes, frown lines between the eyebrows and nasolabial folds around the mouth).
What are the benefits of peptides for the skin?
Polypeptides are scientifically recognized for their effectiveness in cosmetics, particularly in anti-aging treatments. Here are the most observed benefits.
Reduction of wrinkles and fine lines
Studies show that regular use of peptides in skin care can reduce the visible signs of skin aging and improve the appearance of wrinkles by 30% in 12 weeks.
Improved elasticity and firmness
By stimulating the production of collagen and elastin, strengthening the skin's support structures, peptides strengthen the skin's support structures. They help restore skin tone and prevent sagging, for improved firmness and a more youthful appearance.
Enhanced hydration
Certain peptides promote water retention in the epidermis, thus sustainably improving the hydration and suppleness of the skin. The hydrolipidic film is strengthened, the skin is better protected against external aggressions.
“Botox-like” effect
Peptides relax the micro-muscle contractions responsible for expression lines, for a natural smoothing effect on the forehead, eye contour and nasolabial folds. Studies show a visible reduction in forehead wrinkles and crow's feet after regular use of skincare products containing specific peptides such as Argireline (“ acetyl hexapeptide-8 ”).
Appeasement and repair
Thanks to their restorative properties, peptides help calm sensitive or irritated skin while supporting cell regeneration.
How to choose a cosmetic treatment containing peptides?
To use peptides effectively, it is essential to know how to recognize them and choose a suitable cosmetic product.
Formulation
First of all, it's important to know that not all types of peptides are created equal. To apply the right care for your needs, it's essential to know how to read labels. Here are the INCI names of the most effective peptides in the cosmetics field:
- Palmitoyl Tripeptide-1: Increases collagen and hyaluronic acid production, reduces signs of aging and improves the appearance of wrinkles.
- Matrixyl 3000 (Palmitoyl Tripeptide-1 & Palmitoyl Tetrapeptide-7): a powerful anti-aging duo to be found in the Nooance-Paris multi-active serum to smooth the skin, hydrate and even out the complexion.
- Copper peptide (copper tripeptide-1): increases collagen and elastin, healing, anti-redness, cell regeneration. The concentrated anti-aging formula of Nooance-Paris Youth Serum with copper peptides intensely stimulates collagen production for firmer and plumper skin.
- Argireline (Acetyl Hexapeptide-8): Botox-like effect, reduction of expression lines. Nooance-Paris Youthful Eye Balm, composed of argireline, effectively targets wrinkles around the eyes and reduces signs of fatigue and aging such as dark circles, puffiness, and fine lines.
Concentration
A peptide concentration between 0.5 and 2% is generally well tolerated by the skin and allows for effective results.
Some peptides like Matrixyl 3000 or Argireline show visible results from 1 to 2.5%, according to clinical studies.
Association with other assets
The benefits of peptides can vary depending on the other ingredients present in skincare products. Some active ingredients are very complementary:
- Vitamin C: skin radiance, reduction of pigment spots (brown spots), fights against free radicals and oxidative stress thanks to its antioxidant power.
- Ceramides: strengthen the skin barrier, maintain hydration and protect the skin from external aggressions.
- Retinol: cell renewal, complete anti-aging action.
Incorporating Peptides into Your Skincare Routine: A Practical Guide
Peptides: for what skin type?
Peptides are well tolerated by all skin types:
- Sensitive skin: Peptides have restorative and soothing properties that are suitable for dry or irritated skin.
- Mature skin: it is a valuable ally in fighting the appearance of signs of aging, regaining firm and visibly rejuvenated skin.
- Normal skin: it may be interesting to integrate peptides into your skincare routine to prevent skin aging.
When to apply a peptide?
Use your peptide-based skincare on clean, dry skin before moisturizer. Apply to skin twice a day, morning and night, for best results.
Peptides in cosmetics: are they safe for the skin?
As with any product, it is essential to follow the instructions for use (concentration, frequency) to avoid unnecessarily overloading the skin. Test the product on a small area before first use.
Peptide is a safe and effective ingredient, with no specific contraindications when the formula is properly concentrated. Consult a dermatologist if you experience side effects such as redness or irritation.
How do peptides differ from other anti-aging active ingredients?
Peptides are true biological messengers: they send signals to boost the natural production of collagen and elastin, and promote skin repair. Unlike retinol or salicylic acid, which can be irritating, they act on the skin deep down without damaging it, making them an ideal anti-aging active ingredient for sensitive or dehydrated skin.
Peptides are a gentle yet effective anti-aging solution. They are suitable for all skin types and can target several needs: wrinkles, loss of firmness, dehydration, and skin barrier repair. Easy to incorporate into a routine, whether for prevention or treatment, peptides help the skin regenerate naturally.
