The Holiderm Complex explained by Dr. Jérôme Paris

Question 1 – What is the Holiderm® Complex, the brand’s patented active and antioxidant signature?
Filmed answer (Dr. Jérôme Paris)

The Holiderm® Complex is our scientific and antioxidant signature, which I developed together with Mélanie.

It combines three complementary natural extracts: grape berries from Château Toulouse-Lautrec, rich in polyphenols; maritime pine bark, known for its powerful antioxidant properties; and calendula flowers, which are soothing and regenerating.

Together, they protect the skin from oxidative stress, stimulate cellular regeneration, and help preserve skin radiance.

It is a unique synergy that acts both against premature aging and to improve overall skin quality.

Question 2 – Why is this combination of actives so effective?

Because it brings together three essential mechanisms of action:

Grape and pine polyphenols neutralize free radicals.
Calendula helps the skin regenerate and regain comfort.
Together, they form a global antioxidant shield, effective in both skincare and food supplements.

This truly represents the common thread of the brand: a holistic beauty approach, Inside & Out.

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.
