Body Serum-in-Oil - HOLIDERMIE | Firmness & Nourishment

How does Collageneer® truly stimulate collagen production?

Collageneer® is a biomimetic active ingredient derived from White Lupin, an innovative upcycling process that recovers plant by-products to extract highly effective molecules. Its mechanism of action relies on stimulating fibroblasts, the skin cells responsible for synthesizing collagen and elastin. By activating these cells, Collageneer® restarts the natural skin regeneration process that aging has slowed down. Result: skin progressively becomes firmer, more toned, more elastic. Unlike other active ingredients that give a temporary illusion of firmness, Collageneer® acts deeply, in the long term. Results are particularly visible after 3 to 4 weeks of regular use, when collagen production has truly increased.

Why a "dry oil" and how does it really work?

A dry oil is formulated with light, volatile oils that instantly penetrate the skin without leaving a greasy residue. Unlike classic oils that remain on the surface and create a persistent oily finish, Holidermie's body Serum-in-Oil absorbs completely in a few seconds. How? The combination of Grape, Maritime Pine, and Jojoba oils — all relatively light and rich in essential fatty acids — is formulated with subtle emulsifiers and nanoparticle technology that facilitates penetration. Result: you get the intense nourishment of oils (rich in lipids, antioxidants, vitamins) without the cosmetic compromise of a greasy finish. Upon absorption, skin is nourished, smoothed, satiny — guilt-free luxury.

What is the best time to apply the Body Serum-in-Oil?

The Body Serum-in-Oil can be used morning and/or evening on clean, dry skin. For maximum effectiveness and complete sensory pleasure, here is the ideal protocol: after showering (morning or evening), apply the serum to the entire body or to targeted areas (thighs, hips, buttocks, arms, décolleté). Massage in upward movements — move from the knee to the hip, from the lower abdomen to the chest — for 2 to 3 minutes. These movements promote the penetration of active ingredients while stimulating circulation and lymphatic drainage. If desired, combine it with the Body Sculpting Gua Sha for an amplified lifting effect. Wait 30 seconds to one minute for complete absorption before dressing. For optimal results (greater firmness and elasticity), use the serum twice a day for at least 28 days.

How do Ceramides strengthen the skin barrier?

Ceramides are natural lipids found in the stratum corneum (the superficial layer of the skin) that play a crucial structural role: they act as a "cement" between skin cells, maintaining their cohesion and preventing dehydration. With age, sun exposure, and environmental factors, Ceramide levels naturally decrease, weakening the skin barrier. The Body Serum-in-Oil incorporates Ceramides to restore this structural integrity. By strengthening this barrier, transepidermal water loss (TEWL) is prevented, which keeps the skin hydrated, protected, and visibly smoother. Combined with nourishing oils and Collageneer®, Ceramides create an optimal skin ecosystem: firm, nourished, hydrated, and resilient skin against external aggressions. 90% of users confirm this preservation of the hydrolipidic film and this overall protection.
