Kombu algae, to repair

Kombu algae, to repair

Used in cosmetics, Kombu seaweed tones, protects and repairs the skin while fighting against premature aging by boosting collagen production.
The skin is smoother and revitalized. It is the winning Kombu! #humourhumourquandtunoustiens

It is the natural protective power of this algae that we have chosen to formulate I'm Not a Mermaid for the body and hands.
A repairing gel, it relieves skin that is tight from repeated contact with water and temperature changes.

👋 CO-CREATION 👋

It is time to give the power back to those who use cosmetics: you!

So we did that! For you, we have created the cosmetic co-creation model: a unique concept that revolutionises the historical model of cosmetics that you already know. The concept: you tell us what you need, what is missing in current products. Then we co-create with you, and the whole community, this product that will finally meet your needs.

It's about time!

Nideco - Co creation cosmetique

🌱 CLEAN BEAUTY 🌱

Just because we are breaking the rules doesn't mean we can't be gentle (for your skin) 💛 We only have clean formulas and that's what matters.

We start from your needs and find the best possible formula and choose the right active natural ingredients: there are only a few but they are all rigorously selected. The formula is clean, without harmful or controversial ingredients and with a minimum of 95% natural ingredients.

💛 BLOOM 💛

Beyond cosmetics, our mission is to share the values that mean a lot to us: accepting ourselves as we are, learning to love ourselves, saying no to beauty standards and other preconceived ideas, shed light on taboo subjects, defending the freedoms of everyone…

And we want to do it with you, we want to talk with you, to exchange with you, to understand you and give you some good mood in your daily life.
