Known for its ability to promote cell regeneration, potassium helps keep skin hydrated and balanced. A vital ally of vitality, potassium helps stimulate skin microcirculation.

Sodium [Na]
An active ingredient with antiseptic and anti-inflammatory properties, sodium boosts hydration and rebalances the skin's PH. Sodium helps keep skin smooth and healthy.

Chondrus Crispus
This active ingredient helps protect the skin and reduce feelings of tightness and discomfort. Nicknamed "Red Algae", Chondrus Crispus is rich in essential fatty acids and phenols.
Potassium [K] and the skin?
An essential mineral for skin well-being, Potassium offers multiple benefits for the skin:
- Balance : Maintains hydration levels by regulating the transfer of water and nutrients between cells.
- How it works : It supports healthy cell function, essential for skin repair and renewal.
- Health : It combats dry skin, contributing to soft, supple skin.
- Defense : Playing a role in the skin's barrier function, it protects against irritation and external aggression.
Potassium is key to keeping skin hydrated and healthy.
Questions / Answers
Who is this serum for?
Repulpant Serum is for all skin types, from the first signs of fatigue, loss of firmness or dehydration.
It is ideal if you :
- Start to notice fine lines or loss of tone;
- Have a dull, lacklustre complexion;
- Look for a skin care product that moisturizes, plumps and smoothes.
💡 Its natural, concentrated formula is just as suitable as a preventive treatment from the age of 25, as it is as a base treatment for mature skin. And it's perfectly tolerated by sensitive skin.
What type of wrinkles does this serum treat?
Repulpant Serum targets the first wrinkles as well as established ones, thanks to its complex of natural active ingredients with global action:
- It plumps dehydration lines;
- It smoothes expression lines thanks to organic rye extract and hyaluronic acid;
- It firms skin and stimulates elasticity with Potassium PCA and Sodium PCA.
💡 A fter 28 days, 95% of users found their skin visibly smoother, and 92% firmer and plumper.
What's the difference with a moisturizer?
The serum acts deep down, where the cream acts on the surface.
Its fluid texture, ultra-concentrated in active ingredients, enables it to target precise needs such as loss of firmness, fine lines or lack of radiance.
The Replumping Serum intensely moisturizes, plumps and smoothes skin texture.
But it does not replace a cream, which forms a protective shield to preserve moisture and shield skin from external aggressors.
💡 Serum + cream = the ideal combo for visibly more supple, toned and luminous skin.
Why has water been replaced in the formula?
At IUM, we replace "inert" water with active, skin-benefiting ingredients.
In the Plumping Serum, water is mostly replaced by :
- Organic Orange Blossom hydrolate, recognized for its soothing, toning and brightening properties;
- Water from the Iroise Sea, rich in minerals and trace elements, remineralizes, protects and rebalances the skin.
💡 A 100% active base, for enhanced efficacy from the very first drop.
Is it suitable for sensitive skin?
Yes, absolutely. Repulpant Serum has been formulated to suit all skin types, including the most sensitive.
💬 97% of users reported suppler, smoother skin, with no sensation of irritation or tightness.
Why does the formula contain Potassium and Sodium?
Because these two trace elements are essential for skin vitality and balance.
- Potassium PCA helps maintain optimal hydration and promotes skin balance, supporting the skin's natural barrier;
- Sodium PCA, naturally present in the skin, improves suppleness, reinforces the moisture barrier and protects against external aggression.
💡 This duo works synergistically to plump, smooth and illuminate the skin, while respecting its natural ecosystem.
