Holidermie antioxidant protection: our cellular shield.

The blog explains that oxidation is a natural phenomenon that can be intensified by stress, pollution, or UV exposure, which can weaken skin cells. To address this, Holidermie developed the Holiderm® Complex, a synergy of antioxidant active ingredients (maritime pine, grape berries, and calendula) that protects the skin from oxidative stress and helps preserve its balance.

Invisible, continuous, natural: oxidation is part of life.

However, under the effects of stress, UV exposure, pollution, or lifestyle factors, it can weaken cells and alter their optimal functioning.

At Holidermie, antioxidant protection has been considered from the very beginning as the foundation of every formula. Even before adding targeted active ingredients, we built a base designed to sustainably support cellular balance.

It is within this approach that the Holiderm® Complex was created, an exclusive and patented antioxidant architecture developed alongside Dr. Jérôme Paris, the brand’s Scientific Director.

Today, he sheds light on the mechanisms of oxidative stress and how to address it in the most effective way.

What is cellular oxidation?

“Oxidation is a natural cellular aggression, intensified by our environment. When it becomes excessive, it disrupts the proper functioning of cells. The goal is not to prevent time from passing, but to preserve their ability to adapt.”

At the skin level, this can result in:
– a less radiant complexion
– more sensitive skin
– a loss of comfort
– weakened natural defense mechanisms.

Can we act against oxidation?

“Yes, by providing active ingredients capable of neutralizing free radicals and strengthening the skin’s natural protection systems.”

This is precisely the role of the Holiderm® Complex, the protective core of our formulas.

The Holiderm® Complex: a protective synergy.

At the heart of our treatments, the Holiderm® Complex combines three highly concentrated active ingredients, selected for their complementarity.

→ Maritime pine bark polyphenols: Known for their powerful protective action against oxidative stress.

→ Grape berry extract: Naturally rich in antioxidants, sourced from vines grown under High Environmental Value agriculture at Château Toulouse-Lautrec.

→ Calendula flower extract: With soothing and smoothing properties, it helps calm inflammatory reactions linked to external aggressions.

Scientific insight

“Grape berries are particularly rich in polyphenols.

Maritime pine enhances their effectiveness.

Calendula completes this synergy with its soothing action.

Together, these active ingredients help protect the skin and support its balance in the face of oxidative stress.”

Protection at the heart of the Holidermie approach

Inside as well as outside, supporting the skin against daily aggressions is a founding principle of our holistic vision.

Protect today.
Maintain balance tomorrow.
Support the skin with precision.

Collagen: your questions, our answers

Everything you need to know about collagen

Is oral collagen really effective?

Yes. According to Dr. Jérôme Paris, several clinical studies and meta-analyses have shown that regular collagen intake improves skin hydration, density, and quality. Results become visible after 8 to 12 weeks of daily use.

What is the difference between marine collagen and vegetarian collagen?

Marine collagen is mainly composed of type I collagen, which supports firmness and helps prevent wrinkles.

Vegetarian collagen, such as Ovoderm®, comes from the inner membrane of the eggshell and contains several types of collagen (I, V, and X), as well as hyaluronic acid and glycosaminoglycans, which strengthen the dermis and improve skin hydration.

What makes Holidermie’s collagen unique?

Holidermie’s formulas combine three essential active ingredients: collagen, vitamin C, and hyaluronic acid. This trio works in synergy to strengthen the skin’s structure and maintain its hydration. The brand offers both marine collagen and a vegetarian Ovoderm® alternative to suit all lifestyles.

How can collagen be incorporated into your beauty routine?

For optimal results, it is recommended to consume about 10 g of hydrolyzed collagen each morning for at least 8 to 12 weeks. Holidermie offers several formats to suit every habit: powder, sticks to mix into a drink, or vegetarian capsules — all within a holistic Inside & Out approach.
