What is cell renewal and why is it important for the skin?

Skin, our largest organ, naturally regenerates itself to stay healthy and resist external aggressions. This fascinating process is called cell renewal . It plays a key role not only in the appearance of our skin, but also in its function as a protective barrier. Let's take a closer look at what this mechanism is, why it's so important, and how to optimize it.

What is cell renewal?

Cell renewal is a natural cycle in which new skin cells are produced in the deeper layers of the epidermis and then gradually migrate to the surface. Once they reach the surface, they replace the dead cells that naturally shed. It is this process that allows the skin to maintain its radiance, softness, and vitality.

But beyond the aesthetic aspect, this renewal is essential for the skin's defense function . Fresh cells ensure better hydration, protect against external aggressions such as UV rays or pollution, and help maintain a strong skin barrier.

A cycle that slows down over time

In a young person, it takes about 28 days for a cell born in the basal layer to reach the surface of the skin. However, this cycle can lengthen with age, stress, excessive sun exposure, or certain hormonal imbalances. From the age of 40-50, renewal can take up to 60 days , or even longer.

A slower cycle leads to a buildup of dead skin cells on the surface, which can lead to dullness, uneven texture, and a weakened skin's ability to defend itself. It also exacerbates signs of aging, such as fine lines and hyperpigmentation.

Why support cell renewal in your beauty routine?

Proper skin renewal means healthy, bright, and smooth skin . When it's disrupted or slowed down, dead skin cells build up, pores can become clogged, and skin loses its radiance. That's where the right skincare comes in.

• Exfoliation , whether chemical (fruit acids, AHA, BHA) or mechanical (scrubs), helps to remove dead cells and restart the process.

• Hydration allows new cells to function better and promotes regeneration.

• Anti-aging active ingredients such as retinol or peptides directly stimulate the production of new cells.

And what about acne?

In acne-prone skin, cell turnover can be too rapid or disorganized, which promotes clogged pores . Dead cells can become trapped in follicles, leading to blackheads and inflammation . A targeted routine aimed at regulating sebum production, gently exfoliating, and supporting renewal is therefore crucial to prevent breakouts.

How do VIBRE Paris treatments stimulate cell renewal?

Each treatment in the VIBRE Paris routine contains a targeted combination of active ingredients that work in harmony to create an optimal environment for skin regeneration. Among these active ingredients, you can find:

🧫 Probiotics

These beneficial microorganisms help strengthen the skin barrier and balance the microbiome. Microbially healthy skin is better equipped to defend and renew itself naturally, without inflammation or imbalances.

🧬 Peptides

As true cellular messengers, peptides stimulate the production of collagen and elastin , while activating cell regeneration. The result: firmer, smoother skin and a revitalized renewal process.

🧱 Ceramides

These lipids, naturally present in the skin, are essential for maintaining hydration and restoring barrier function. By protecting the skin from external aggressions, ceramides allow new cells to settle in a stable and soothed environment.

🌿 P-Refinyl

This innovative plant-based active ingredient, derived from the mastic tree, visibly tightens pores and improves skin texture. By refining skin texture, it promotes a more even surface that better reflects light—a sign of renewed skin.
