Natural peptides have become one of the most studied and effective anti-aging active ingredients. These short chains of amino acids act as messengers that stimulate key processes in the skin, offering visible results in elasticity and firmness from the first application.
What are natural peptides?
Peptides are molecules made up of chains of amino acids that, when applied topically, send signals to skin cells to promote collagen and elastin production. Because they are biotechnologically derived or derived from plant sources, they offer high compatibility and minimal irritation.
Origin and obtaining
They are obtained through plant fermentation or enzymatic synthesis, processes that guarantee purity and optimal concentration without resorting to aggressive synthetic ingredients.
Common types in formulations
Among the most used are:
| Molecule | Molecular size | Function |
|---|---|---|
| Matrixyl | ~800 Da | Stimulates collagen |
| Copper peptides | ~1,000 Da | Cellular repair |
| Nonapeptide-1 | ~1,000 Da | Internal clock stimulation, Illumination and even tone ( TEIA peptide serum ) |
Main benefits of peptides on the skin
Collagen stimulation
Peptides send signals to fibroblasts to increase collagen formation, improving firmness and reducing sagging in just a few weeks.
Hydration and firmness
They act as moisturizing agents that strengthen the skin barrier, retaining water and providing a denser, more uniform appearance.
Reduction of wrinkles and expression lines
With continued use, skin texture is smoothed and fine lines are softened thanks to the improvement of the extracellular matrix.
How to integrate peptides into your anti-aging routine
- Step 1: Gentle Cleansing: Remove impurities with a sulfate-free cleanser to prepare skin and optimize absorption.
- Step 2: Applying peptide serum: Apply 2–3 drops to your face and neck, massaging gently in upward motions.
- Step 3: Hydration and Protection: Seal the serum with your favorite moisturizer and apply sunscreen every morning.
Additional tips to boost results
Combine peptides with vitamin C in the morning to protect against free radicals, and with niacinamide at night to strengthen the lipid barrier. Alternate its use with mild retinoids to maximize cell renewal without irritation.
Frequently Asked Questions
Can I use peptides day and night?
Yes, peptides are compatible with both schedules: in the morning they protect and stimulate collagen, and at night they support cell repair.
Are they safe for sensitive skin?
Being natural and low in irritant concentration, they are usually very well tolerated, although it is recommended to do a test on the inner area of the forearm.
How long does it take to see results?
Visible improvements in firmness and texture are observed between 4 and 6 weeks of constant use.
