Collagen and peptides: what do they really do for our skin?

In the world of skincare, collagen and peptides are among the most talked-about ingredients. They can be found in creams, serums and facial treatments, often associated with benefits such as firmer, smoother and more radiant skin.

But what do they really do? And why are they so important in a daily skincare routine?

Collagen: the structure of the skin

Collagen is a fundamental protein naturally present in our skin. It plays a key role in keeping it:

• Elastic

• Firm

• Resilient

Over time, however, collagen production decreases. This natural process leads to the appearance of:

• Wrinkles and fine lines

• Loss of firmness

• Thinner, less even-looking skin

This is where skincare comes into play.

Peptides: small actives, big benefits

Peptides are short chains of amino acids that act as “messengers” for the skin.

When applied topically through cosmetic products, they can help:

• Support a firmer-looking complexion

• Improve skin texture

• Make the skin look visibly smoother

They are particularly popular because they are generally well tolerated and suitable for different skin types.

Collagen in cosmetics: what to expect

When you find collagen listed among the ingredients in a cream, it is important to know that its main functions are to:

• Hydrate the skin

• Improve the feeling of elasticity

• Create a film-forming effect that leaves the skin feeling softer and smoother

Collagen in cosmetics does not directly penetrate deep into the skin to “rebuild” natural collagen, but it can help visibly improve the skin’s appearance.

How to incorporate them into your skincare routine

To get the most out of these ingredients, collagen and peptides can be incorporated into a simple yet effective routine:

• Peptide serum: ideal for application after cleansing

• Moisturising cream with collagen: to maintain skin softness and elasticity

• Sun protection: essential for preserving natural collagen

  
  

Collagen and peptides work best as part of a complete skincare routine, alongside proper cleansing and protection from UV rays, one of the main factors contributing to skin ageing.

Taking care of your skin also means choosing targeted active ingredients and using them consistently, without expecting immediate solutions but focusing instead on gradual, natural-looking results.
