Peptides and cellular regeneration: the secrets to firm and radiant skin

With age, stress, and external aggressions, the production of collagen and elastin decreases, leading to a loss of skin firmness. By stimulating cellular regeneration and strengthening the extracellular matrix, peptides help preserve skin structure and maintain firmer, more resilient skin.

At Ad CAELIA, we are committed to optimizing your skin’s health daily by incorporating targeted active ingredients and highly efficient synergies into our skincare formulations. Today, we explain why we have chosen to include peptides in our product line and their numerous benefits for your skin.

 

What is a peptide?

Peptides are protein fragments made up of several amino acids linked together. In skincare, they are often used for their ability to send signals to skin cells, stimulating the natural production of collagen, elastin, and other essential components for overall skin health.

Different types of peptides used in cosmetics

In the world of cosmetics, peptides are widely used for their anti-aging, hydrating, firming, and repairing properties. Here is a classification of the most commonly used peptides and their key effects on the skin:

 

1. Signaling peptides:

• These stimulate the production of collagen, elastin, and other skin proteins. They are the most widely used in cosmetics as they send signals to cells to boost collagen and elastin production, thereby improving skin firmness and elasticity.
• Effects: Anti-aging and firming; they enhance skin tone and texture.

 

2. Neurotransmitter-Inhibiting Peptides (Botox-like effect):

• These work by blocking neuronal signals responsible for muscle contractions, thereby reducing the appearance of expression lines.
• Effects: Smoothing, anti-wrinkle; they provide an immediate tightening effect.

 

3. Carrier Peptides:

• They transport essential trace elements such as copper or magnesium to skin cells, enhancing regeneration by improving the penetration and efficacy of active ingredients.
• Effects: Repairing and healing.

 

4. Anti-inflammatory and Repair Peptides:

• These peptides help soothe inflammation, reduce redness, and promote skin healing.
• Effects: Soothing and repairing; they also help reduce pigmentation spots.

 

5. Hydration-Boosting Peptides:

• They stimulate hyaluronic acid production, improving skin hydration.
• Effects: Hydrating and plumping.

 

A key role in collagen stimulation

Peptides play a crucial role in stimulating the natural production of collagen, a protein essential for skin structure and firmness. These molecules, composed of short chains of amino acids, act as biological messengers capable of signaling fibroblasts—the cells responsible for collagen production—to intensify their activity.

Among them, signaling peptides are particularly effective in boosting collagen and elastin synthesis, reducing the appearance of wrinkles and improving skin elasticity. Additionally, carrier peptides promote tissue repair and strengthen the extracellular matrix by delivering essential trace elements.

Ad CAELIA’s patented peptides: excellence in skincare

Ad CAELIA incorporates innovative and patented peptides into its skincare products, specially designed to enhance your skin and fight signs of aging.

Our iconic Multipurpose power eye cream "Sparkle of Joy", features a highly efficient synergy, in which IPeptide - Good Night’s Sleep plays a key role. This signaling peptide promotes relaxation and optimizes regeneration around the eye contour—the most sensitive and delicate area of our skin. It helps maintain hydration, stimulates collagen production, and reduces redness, inflammation, and irritation. With its decongesting and refreshing action, the skin regains suppleness, elasticity, and radiance upon waking.

For an optimized skincare routine, our Ultra moisturizing smoothing cream "Like a Dream" includes Tri-Peptide - Matrixyl Morphomics, a patented anti-aging active ingredient that works deep within the skin to improve texture and density. This peptide stimulates collagen production and supports extracellular matrix restructuring, visibly reducing wrinkles and firming facial contours.

Through these high-performance peptide synergies, Ad CAELIA offers an advanced beauty approach, combining the best of science and nature for visibly firmer and more radiant skin.

 

How to maximize the effectiveness of peptides in your skincare routine

To enhance the benefits of peptides, it is essential to combine them with antioxidants and hydrating agents, reinforcing their regenerating and protective actions.

• Integrate peptide-rich treatments with complementary active ingredients :
  Our Multipurpose power eye cream "Sparkle of Joy" combines IPeptide - Good Night’s Sleep with triple-weight hyaluronic acid, black crowberry, ash extract, and rose extract, all known for their antioxidant properties, helping to revitalize and protect the skin from oxidative stress.
• Apply peptide-enriched serums and creams morning and night :
  For visible results, peptides should be incorporated into your daily beauty routine. Our Ultra moisturizing smoothing cream "Like a Dream" contains a highly effective tripeptide that deeply stimulates skin regeneration.
• Combine peptides with other active ingredients for a synergistic action :
  Whether in our serum or eye contour treatment, both feature complex formulations, combining peptides with superactive hydrating and antioxidant agents for visibly firmer, more radiant skin.

Are there any contraindications to using peptide-based skincare?

The peptides used by Ad CAELIA have been carefully sourced, primarily from Scandinavian countries and Europe, and selected for their high quality and biomimetic profile (they have an identical structure to protein fragments already present in the body). As a result, there are no contraindications to the topical use of peptide-based skincare. Pregnant and/or breastfeeding women can also use them safely.

Thanks to their exceptional properties, peptides have become essential active ingredients, offering an innovative and targeted approach to preserving youthful, firm, and toned skin. Integrating peptides into your skincare routine can be an effective strategy for maintaining a firm, elastic, and radiantly healthy complexion.
